Summary of Significant Accounting Policies | 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited condensed consolidated financial statements of ADTRAN ® In the opinion of management, all adjustments necessary to fairly state these interim statements have been recorded and are of a normal and recurring nature. The results of operations for an interim period are not necessarily indicative of the results for the full year. The interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in ADTRAN’s Annual Report on Form 10-K for the year ended December 31, 2018, filed with the SEC on February 28, 2019 (as amended on September 20, 2019, the “2018 Form 10-K”). Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Our more significant estimates include the excess and obsolete inventory reserves, warranty reserves, customer rebates, determination of the deferred and accrued revenue components of multiple performance obligations sales agreements, estimated costs to complete obligations associated with deferred and accrued revenue, estimated income tax provision and income tax contingencies, the fair value of stock-based compensation, impairment of goodwill, valuation and estimated lives of intangible assets, estimated pension liability, fair value of investments and the evaluation of other-than-temporary declines in the value of investments. Actual amounts could differ significantly from these estimates. During the three months ended June 30, 2019, the Company revised the methodology used in estimating its excess and obsolete inventory reserves. Under the revised methodology, we establish reserves for estimated excess and obsolete inventory equal to the difference between the cost of the inventory and the estimated net realizable value of the inventory based on historical usage, known trends, inventory age, and market conditions. When we dispose of excess and obsolete inventories, the related disposals are charged against the inventory reserves. See Note 8 for additional information. Correction of Immaterial Misstatements During the three months ended June 30, 2019, the Company determined that there was an immaterial misstatement of its excess and obsolete inventory reserves in its previously issued annual and interim financial statements. The Company corrected this misstatement by recognizing a $0.8 million out-of-period adjustment during the three months ended June 30, 2019, which increased its excess and obsolete inventory reserves and cost of goods sold for the period. For the six months ended June 30, 2019, the out-of-period adjustment was a cumulative $0.2 million reduction in the Company’s excess and obsolete inventory reserves and cost of goods sold. In addition, the Company determined that a $1.0 million cash inflow related to an insurance recovery was incorrectly classified as a cash flow from operations instead of a cash flow from investing activities within the unaudited Condensed Consolidated Statement of Cash Flows for the three months ended March 31, 2019. The Company has corrected this misstatement in the Unaudited Condensed Consolidated Statement of Cash Flows for the nine months ended September 30, 2019 to correctly reflect the $1.0 million insurance recovery as a cash inflow from investing activities. Management has determined that these misstatements were not material to any of its previously issued financial statements and that correction of the misstatements is also not material to the current or estimated annual 2019 financial results on either a quantitative and qualitative basis.

Recently Adopted Accounting Pronouncements During 2019, we adopted the following accounting standards, which had the following impacts on our consolidated financial statements: In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), Codification Improvements to Topic 842 Leases Leases (Topic 842), Targeted Improvements Leases (Topic 840) Leases (Topic 842) Codification Improvements The Company adopted the new standard on January 1, 2019, the effective date of our initial application, using the optional transition method. At that time, the Company elected to carry forward the legacy ASC 840 disclosures for comparative periods and, therefore, did not adjust the comparative period financial information prior to January 1, 2019. In addition, the Company elected the package of practical expedients which allows for companies to not reassess whether any expired or existing contracts are or contain leases, not reassess historical lease classifications for expired or existing contracts and not reassess initial direct costs for existing leases. Additionally, the Company elected the practical expedients which allow the use of hindsight when determining the lease term, the short-term lease recognition exemption and the option to not separate lease and non-lease components. The adoption of this standard resulted in the recognition of a right-of-use asset and corresponding right-of-use liability on our Condensed Consolidated Balance Sheet of $10.3 million as of January 1, 2019, primarily related to our operating leases for office space, automobiles and other equipment. As a lessee, the adoption of this standard did not have a material impact on our Condensed Consolidated Statement of Income or Statement of Cash Flows. See Note 12 for additional information. As a lessor, the adoption of this standard did not have a material impact on the Company’s Condensed Consolidated Balance Sheet, Condensed Consolidated Statement of Income or Condensed Consolidated Statement of Cash Flows. Prior to and after adoption, all of our leases in which we are the lessor were classified as sales-type leases.

Business Combinations [Abstract] | |
Business Combinations | 2. BUSINESS COMBINATIONS On November 30, 2018, we acquired SmartRG, Inc. (“SmartRG”), a provider of carrier-class, open connected home platforms and cloud services for broadband service providers in exchange for cash consideration. This transaction was accounted for as a business combination. We have included the financial results of this acquisition in our consolidated financial statements since the date of acquisition. The revenue from the SmartRG portfolio is included in the Subscriber Solutions & Experience category within the Network Solutions and Services & Support reportable segments. Contingent liabilities with a fair value totaling $1.2 million were recognized at the acquisition date, the payments of which were dependent upon SmartRG achieving future revenue, EBIT or customer purchase order milestones during the first half of 2019. The required milestones were not achieved and, therefore, we recognized a gain of $1.2 million upon the reversal of these liabilities during the second quarter of 2019. An escrow in the amount of $2.8 million was set up at the acquisition date to fund post-closing working capital settlements and to satisfy indemnity obligations to the Company arising from any inaccuracy or breach of representations, warranties, covenants, agreements or obligations of the sellers. The escrow is subject to arbitration with final settlement expected during the fourth quarter of 2020. The minimum and maximum potential release of funds to the sellers ranges from zero to $2.8 million. We recorded goodwill of $3.5 million as a result of this acquisition, which represents the excess of the purchase price over the fair value of net assets acquired. We assessed the recognition and measurement of the assets acquired and liabilities assumed based on historical and forecasted data for future periods and concluded that our valuation procedures and resulting measures were appropriate. The final allocation of the purchase price to the estimated fair value of the assets acquired and liabilities assumed at the acquisition date for SmartRG are as follows: (In thousands) Assets Tangible assets acquired $ 8,594 Intangible assets 9,960 Goodwill 3,476 Total assets acquired 22,030 Liabilities Liabilities assumed (6,001 ) Total liabilities assumed (6,001 ) Total purchase price $ 16,029 The details of the acquired intangible assets from the SmartRG acquisition are as follows: (In thousands) Value Life (in years) Developed technology $ 7,400 7 Customer relationships 1,790 3 Licensing agreements 560 5 – 10 Trade name 210 3 Total $ 9,960 For the three and nine months ended September 30, 2019, we incurred acquisition and integration related expenses and On March 19, 2018, we acquired Sumitomo Electric Lightwave Corp.’s North American EPON business and entered into a technology license and OEM supply agreement with Sumitomo Electric Industries, Ltd. This transaction was accounted for as a business combination. We have included the financial results of this acquisition in our consolidated financial statements since the date of acquisition. This revenue is included in the Access & Aggregation and Subscriber Solutions & Experience categories within the Network Solutions reportable segment. We recorded a bargain purchase gain, net of income taxes, of $11.3 million during the first quarter of 2018, which represents the difference between the fair value of the net assets acquired over the cash paid. We assessed the recognition and measurement of the assets acquired and liabilities assumed based on historical and forecasted data for future periods and concluded that our valuation procedures and resulting measures were appropriate. The following unaudited supplemental pro forma information presents the financial results of the Company for the nine months ended September 30, 2018 as if the acquisition of the Sumitomo EPON business had occurred on January 1, 2018. This unaudited supplemental pro forma information does not purport to be indicative of what would have occurred had the acquisition been completed on January 1, 2018, nor is it indicative of any future results. There were no material, non-recurring adjustments to this unaudited pro forma information.

Revenue | 3. REVENUE The following is a description of the principal activities from which we generate our revenue by reportable segment. Network Solutions Segment Network Solutions includes hardware products and software-defined next-generation virtualized solutions used in service provider or business networks, as well as prior generation products. The majority of the revenue from this segment is from hardware sales. In certain transactions, we are also the lessor in sales-type lease arrangements for network equipment. These arrangements typically include network equipment, network implementation services and maintenance services. Network implementation services and maintenance services are included in the Services & Support segment discussed below. See Note 12 for additional information. Services & Support Segment To complement our Network Solutions segment, we offer a complete portfolio of maintenance, network implementation, solutions integration and managed services, which include hosted cloud services and subscription services. Sales by Category In addition to our reporting segments, we also report revenue in the following three categories – Access & Aggregation, Subscriber Solutions & Experience and Traditional & Other Products. The following table disaggregates our revenue by reportable segment and revenue category for the three months ended September 30, 2019 and 2018: Three Months Ended September 30, 2019 September 30, 2018 (In thousands) Network Solutions Services & Support Total Network Solutions Services & Support Total Access & Aggregation $ 48,902 $ 16,212 $ 65,114 $ 76,046 $ 15,855 $ 91,901 Subscriber Solutions & Experience (1) 40,382 2,094 42,476 37,313 1,239 38,552 Traditional & Other Products 4,734 1,768 6,502 7,684 2,198 9,882 Total $ 94,018 $ 20,074 $ 114,092 $ 121,043 $ 19,292 $ 140,335 (1) The following table disaggregates our revenue by reportable segment and revenue category for the nine months ended September 30, 2019 and 2018 : Nine Months Ended September 30, 2019 September 30, 2018 (In thousands) Network Solutions Services & Support Total Network Solutions Services & Support Total Access & Aggregation $ 230,837 $ 43,476 $ 274,313 $ 220,653 $ 37,670 $ 258,323 Subscriber Solutions & Experience (1) 113,545 6,186 119,731 99,396 3,817 103,213 Traditional & Other Products 14,625 5,605 20,230 21,310 6,343 27,653 Total $ 359,007 $ 55,267 $ 414,274 $ 341,359 $ 47,830 $ 389,189 (1) Revenue is measured based on the consideration we expect to receive in exchange for transferring goods or providing services to a customer and as performance obligations under the terms of the contract are satisfied. For transactions where there are multiple performance obligations, we account for individual products and services separately if they are distinct (if a product or service is separately identifiable from other items and if a customer can benefit from it on its own or with other resources that are readily available to the customer). As of September 30, 2019, we did not have any significant performance obligations related to customer contracts that had an original expected duration of one year or more, other than maintenance services, which are satisfied over time. The following table provides information about receivables, contract assets and unearned revenue from contracts with customers: (In thousands) September 30, 2019 December 31, 2018 Accounts receivable, net $ 90,647 $ 99,385 Contract assets (1) $ 2,434 $ 3,766 Unearned revenue $ 14,022 $ 17,940 Non-current unearned revenue $ 4,581 $ 5,296 (1) Of the outstanding unearned revenue balance at December 31, 2018, $1.2 million and $11.7 million was recognized as revenue during the three and nine months ended September 30, 2019, respectively. |

Income Taxes | 4. INCOME TAXES Our effective tax rate increased from a benefit of 34.9%, excluding the tax effect of the bargain purchase gain, in the nine months ended September 30, 2018, to an expense of 197.1% in the nine months ended September 30, 2019. The increase in the effective tax rate between the two periods was primarily driven by the establishment of a valuation allowance against our domestic deferred tax assets in the amount of $37.1 million during the three months ended September 30, 2019, offset by a 9.38% rate reduction related to a transfer pricing study completed during the second quarter of 2019 that resulted in the assignment of operating expenditures to specific company locations, and the effective income tax rates among the respective jurisdictions. As of September 30, 2019, the Company had deferred tax assets totaling $49.4 million. As of September 30, 2019, a valuation allowance totaling $42.9 million has been established against our deferred tax assets. Of this amount, $37.1 million was established during the third quarter of 2019 relating to our domestic deferred tax assets. The remaining $5.8 million that was established in prior periods relates to state research and development credit carryforwards, and foreign net operating loss and research and development credit carryforwards, where we lack sufficient activity to realize those deferred tax assets. The remaining $6.5 million in deferred tax assets not offset by a valuation allowance are located in various foreign jurisdictions where the Company believes it is more likely than not we will realize these deferred tax assets. Supplemental balance sheet information related to deferred tax assets is as follows: September 30, 2019 (In thousands) Deferred Tax Assets Valuation Allowance Deferred Tax Assets, net Domestic $ 40,496 $ (40,496 ) $ — International 8,909 (2,417 ) 6,492 Total $ 49,405 $ (42,913 ) $ 6,492 The Company continually reviews the adequacy of our valuation allowance and recognizes the benefits of deferred tax assets only as the reassessment indicates that it is more likely than not that the deferred tax assets will be realized in accordance with ASC 740, Income Taxes |

Unrecognized compensation expense will be adjusted for actual forfeitures. All of the options above were issued at exercise prices that approximated fair market value at the date of grant. The aggregate intrinsic value of stock options represents the total pre-tax intrinsic value (the difference between ADTRAN’s closing stock price on the last trading day of the quarter and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on September 30, 2019. The amount of aggregate intrinsic value will change based on the fair market value of ADTRAN’s stock and was zero as of September 30, 2019. The total pre-tax intrinsic value of options exercised during the nine months ended September 30, 2019 was $0.1 million. The fair value of our stock options is estimated using the Black-Scholes model. The determination of the fair value of stock options on the date of grant using the Black-Scholes model is affected by our stock price, as well as assumptions regarding a number of complex and subjective variables that may have a significant impact on the fair value estimate. These variables include, but are not limited to, the volatility of our stock price and employee exercise behaviors. There were no stock options granted during the three and nine months ended September 30, 2019 and 2018. PSUs, RSUs and Restricted Stock The following table is a summary of our PSUs, RSUs and restricted stock outstanding as of December 31, 2018 and September 30, 2019 and the changes that occurred during the nine months ended September 30, 2019. Number of Shares (in thousands) Weighted Avg. Grant Date Fair Value (per share) Unvested PSUs, RSUs and restricted stock outstanding, December 31, 2018 1,570 $ 18.52 PSUs, RSUs and restricted stock granted 63 $ 12.81 PSUs, RSUs and restricted stock vested (22 ) $ 17.13 PSUs, RSUs and restricted stock forfeited (175 ) $ 18.69 Unvested PSUs, RSUs and restricted stock outstanding, September 30, 2019 1,436 $ 18.27 The fair value of our PSUs with market and performance conditions is calculated using a Monte Carlo simulation valuation method. The fair value of RSUs and restricted stock is equal to the closing price of our stock on the business day immediately preceding the grant date. At September 30, 2019, total unrecognized compensation expense related to the non-vested portion of market-based PSUs, RSUs and restricted stock was approximately $11.6 million, which is expected to be recognized over an average remaining recognition period of 2.4 years. In addition, there was $8.2 million of unrecognized compensation expense related to unvested 2017 performance-based PSUs, which will be recognized over the remaining requisite service period of 0.3 years if achievement of the performance obligation becomes probable. For the three and nine months ended September 30, 2019 and 2018, no compensation expense was recognized related to these 2017 performance-based PSUs. Unrecognized compensation expense will be adjusted for actual forfeitures. |

Realized gains and losses on sales of debt securities are computed under the specific identification method. The following table presents gross realized gains and losses related to our debt securities: Three Months Ended Nine Months Ended September 30, September 30, (In thousands) 2019 2018 2019 2018 Gross realized gains on debt securities $ 36 $ 24 $ 85 $ 49 Gross realized losses on debt securities (7 ) (50 ) (40 ) (365 ) Total gain (loss) recognized, net $ 29 $ (26 ) $ 45 $ (316 ) Our investment policy provides limitations for issuer concentration, which limits, at the time of purchase, the concentration in any one issuer to 5% of the market value of our total investment portfolio. At September 30, 2019, we held a $25.6 million restricted certificate of deposit that is carried at cost and matures on January 8, 2020. This investment serves as a collateral deposit against the principal amount outstanding under loans made to ADTRAN pursuant to an Alabama State Industrial Development Authority revenue bond (the “Bond”), which totaled $25.6 million at September 30, 2019 and December 31, 2018. At September 30, 2019 and December 31, 2018, the estimated fair value of the Bond using a level 2 valuation technique was approximately $25.6 million and $25.4 million, respectively, based on a debt security with a comparable interest rate and maturity and a Standard and Poor’s credit rating of AA+. We have the right to offset the balance of the Bond with the collateral deposit in order to reduce the balance of the indebtedness. The Bond matures on January 1, 2020, and bears interest at the rate of 2% per annum. In conjunction with this program, we are eligible to receive certain economic incentives from the State of Alabama that reduce the amount of payroll withholdings we are required to remit to the state for those employment positions that qualify under this program. We are required to make payments in the amounts necessary to pay the interest on the amounts currently outstanding. We have made annual principal payments in addition to the interest amounts that are due. The restricted funds held as collateral against the outstanding principal amount of the Bond will be used to pay the outstanding principal and interest upon the Bond’s maturity. Marketable Equity Securities Our marketable equity securities consist of publicly traded stock, funds and certain other investments measured at fair value or cost (where appropriate). On January 1, 2018, we adopted ASU 2016-01, which requires us to measure all equity investments that do not result in consolidation and are not accounted for under the equity method at fair value, with any changes in fair value recognized in net investment gain (loss). Upon adoption, we reclassified $3.2 million of net unrealized gains related to marketable equity securities from accumulated other comprehensive income (loss) to retained earnings. ASU 2016-01 also provides a measurement alternative for equity investments that do not have a readily determinable fair value in which investments can be recorded at cost less impairment, if any, adjusted for observable price changes for an identical or similar investment. We elected to record our equity investment that does not have a readily determinable fair value using the measurement alternative method. As of December 31, 2018, the Company had a note receivable of approximately $4.3 million, which was included in other receivables on the Condensed Consolidated Balance Sheet. During the three months ended March 31, 2019, this amount was repaid and reissued in the form of debt and equity. Approximately $3.4 million was issued as an equity investment, which represented a non-cash investing activity. The carrying value of this investment under the measurement alternative was $3.4 million as of September 30, 2019. The remaining amount, approximately $0.9 million, was converted into a new note receivable, which is included in other receivables on the Condensed Consolidated Balance Sheet and represents a non-cash operating activity. Realized and unrealized gains and losses for our marketable equity securities for the three and nine months ended September 30, 2019 and 2018 were as follows: Three Months Ended Nine Months Ended September 30, September 30, (In thousands) 2019 2018 2019 2018 Realized gains (losses) on equity securities sold $ (20 ) $ 1,240 $ (83 ) $ 1,587 Unrealized gains (losses) on equity securities held (225 ) 3,293 8,233 4,129 Total gain (loss) recognized, net $ (245 ) $ 4,533 $ 8,150 $ 5,716 As of September 30, 2019 and 2018, gross unrealized losses related to individual investments in a continuous loss position for twelve months or longer were not material. We have categorized our cash equivalents and our investments held at fair value into a three-level fair value hierarchy based on the priority of the inputs to the valuation technique for the cash equivalents and investments as follows: Level 1 - Values based on unadjusted quoted prices for identical assets or liabilities in an active market; Level 2 - Values based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly; Level 3 - Values based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs include information supplied by investees.

We review long-lived assets used in operations for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable and the undiscounted cash flows estimated to be generated by the asset are less than the asset’s carrying value. During the three and nine months ended September 30, 2019, the Company recognized impairment charges of $3.9 million related to the abandonment of certain information technology projects in which we had previously capitalized costs related to these projects. The impairment charges were determined based on actual costs incurred as part of the projects. |

Goodwill Disclosure [Abstract] | |
Goodwill | 10. GOODWILL Goodwill, all of which relates to our acquisitions of Bluesocket, Inc. in 2011 and SmartRG in 2018, was $7.0 million and $7.1 million at September 30, 2019 and December 31, 2018, respectively, of which $6.6 million and $0.4 million was allocated to our Network Solutions and Services & Support reportable segments, respectively, as of September 30, 2019, and of which $6.7 million and $0.4 million was allocated to our Network Solutions and Services & Support reportable segments, respectively, as of December 31, 2018. Goodwill related to our SmartRG acquisition was reduced by $0.1 million during the nine months ended September 30, 2019 as a result of a measurement period adjustment. We evaluate the carrying value of goodwill during the fourth quarter of each year and between annual evaluations if events occur or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. We have elected to first assess the qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit to which the goodwill is assigned is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step impairment test. If we determine that it is more likely than not that its fair value is less than its carrying amount, then the two-step impairment test will be performed. Based on the results of our qualitative assessment in the fourth quarter of 2018 , we concluded that it was not necessary to perform the two-step impairment test. No events or circumstances occurred during the nine months ended September 30, 2019 that would more likely than not reduce the fair value of goodwill below its carrying value. |

Leases [Abstract] | |
Leases | 12. LEASES Operating Leases We have operating leases for office space, automobiles, and various other equipment in the United States and in certain international locations in which we do business. We also have other contracts, such as manufacturing agreements and service agreements, which we reviewed to determine if they contain any embedded leases. We specifically reviewed these other contracts to determine whether we have the right to substantially all of the economic benefit from the use of any specified assets or the right to direct the use of any specified assets, either of which would indicate the existence of a lease. As of September 30, 2019, our operating leases have remaining lease terms of two months to six years, some of which include options to extend the leases for up to five years, and some of which include options to terminate the leases within three months Supplemental balance sheet information related to operating leases is as follows: September 30, January 1, (In thousands) Classification 2019 2019 (1) Assets Operating lease asset Other assets $ 18,529 $ 10,322 Total lease assets $ 18,529 $ 10,322 Liabilities Current operating lease liability Accrued expenses $ 3,063 $ 2,948 Non-current operating lease liability Other non-current liabilities 15,659 7,374 Total lease liability $ 18,722 $ 10,322 (1) The components of lease expense included in the Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2019 were as follows: (in thousands) Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 Selling, general and administrative expenses $ 352 $ 1,050 Research and development expenses 847 1,731 Cost of sales 16 49 Total operating lease expense $ 1,215 $ 2,830 As of September 30, 2019, operating lease liabilities included on the Condensed Consolidated Balance Sheet by future maturity were as follows: (In thousands) Amount Remainder of 2019 $ 1,044 2020 3,417 2021 3,071 2022 2,672 2023 2,350 Thereafter 8,258 Total lease payments 20,812 Less: Interest (2,090 ) Present value of lease liabilities $ 18,722 Future o perating lease payments include $7.6 million related to options to extend lease terms that are reasonably certain of being exercised. There are no legally binding leases that have not yet commenced A s of December 31, 2018, future minimum rental payments under non-cancelable operating leases, including renewals determined to be reasonably assured as of December 31, 2018, with original maturities of greater than 12 months, were as follows: (In thousands) Amount (1) 2019 $ 3,873 2020 3,580 2021 2,771 2022 2,053 2023 1,317 Thereafter 762 Total $ 14,356 (1) Certain renewal options were subsequently determined to not be reasonably assured of renewal upon the Company’s adoption of the new lease accounting standard on January 1, 2019. Our leases do not provide an implicit borrowing rate and therefore we use an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We used the incremental borrowing rate on January 1, 2019, for operating leases that commenced on or prior to that date. The incremental borrowing rate was determined on a portfolio basis by grouping leases with similar terms as well as grouping leases based on a U.S. dollar or Euro functional currency. The actual rate is then determined based on a credit spread over LIBOR as well as the Bloomberg Curve Matrix for the U.S. Communications section. The following table provides information about our weighted average lease terms and weighted average discount rates as of September 30, 2019: September 30, 2019 Weighted average remaining lease term (years) Operating leases with USD functional currency 8.4 Operating leases with Euro functional currency 4.6 Weighted average discount rate Operating leases with USD functional currency 3.22 % Operating leases with Euro functional currency 1.84 % Supplemental cash flow information related to operating leases is as follows: Nine Months Ended (In thousands) September 30, 2019 Cash paid for amounts included in the measurement of operating lease assets / liabilities Cash used in operating activities related to operating leases $ (775 ) Right-of-use assets obtained in exchange for lease obligations $ 21,418 Sales-Type Lease s We are the lessor in sales-type lease arrangements for network equipment, which have initial terms of up to five years. Our sales-type lease arrangements contain either a provision whereby the network equipment reverts back to us upon the expiration of the lease or a provision that allows the lessee to purchase the network equipment at a bargain purchase amount. In addition, our sales-type lease arrangements do not contain any residual value guarantees or material restrictive covenants. The allocation of the consideration between lease and non-lease components is determined by standalone sales price by component. The net investment in sales-type leases consists of lease receivables less unearned income. Collectability of sales-type leases is evaluated periodically at an individual customer level. At September 30, 2019 and December 31, 2018, we had no allowance for credit losses for our net investment in sales-type leases. As of September 30, 2019 and December 31, 2018, the components of the net investment in sales-type leases were as follows: September 30, December 31, (In thousands) 2019 2018 Current minimum lease payments receivable (1) $ 3,643 $ 11,339 Non-current minimum lease payments receivable (2) 1,073 1,670 Total minimum lease payments receivable 4,716 13,009 Less: Current unearned revenue 445 631 Less: Non-current unearned revenue 210 473 Net investment in sales-type leases $ 4,061 $ 11,905 (1) Included in other receivables on the Condensed Consolidated Balance Sheet.

These stock options were excluded because their exercise prices were greater than the average market price of the common shares, during the quarter, therefore making them anti-dilutive under the treasury stock method. As a result of the net loss for the three months ended September 30, 2019, and for the nine months ended September 30, 2019 and 2018, 4.1 million, 3.0 million and 2.3 million, respectively, shares of unvested stock options, PSUs, RSUs and restricted stock were excluded from the calculation of diluted EPS due to their anti-dilutive effect. |

Segment Reporting [Abstract] | |
Segment Information | 15. SEGMENT INFORMATION We operate in two reportable segments: (1) Network Solutions and (2) Services & Support. Network Solutions includes hardware products and software defined next-generation virtualized solutions used in service provider or business networks, as well as prior-generation products. Services & Support includes our suite of ProCloud managed services, network installation, engineering and maintenance services and fee-based technical support and equipment repair/replacement plans. We evaluate the performance of our segments based on gross profit; therefore, selling, general and administrative expenses, research and development expenses, interest and dividend income, interest expense, net investment gain (loss), other income (expense) and (provision) benefit for income taxes are reported on a company-wide, functional basis only. There is no inter-segment revenue. The following table presents information about the sales and gross profit of our reportable segments for the three and nine months ended September 30, 2019 and 2018. We do not produce asset information by reportable segment; therefore, it is not reported.

Product Warranties Disclosures [Abstract] | |
Liability for Warranty Returns | 16. LIABILITY FOR WARRANTY RETURNS Our products generally include warranties of 90 days to five years for product defects. We accrue for warranty returns at the time revenue is recognized based on our estimate of the cost to repair or replace the defective products. We engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers. Our products continue to become more complex in both size and functionality as many of our product offerings migrate from line card applications to total systems. The increasing complexity of our products will cause warranty incidences, when they arise, to be more costly. Our estimates regarding future warranty obligations may change due to product failure rates, material usage and other rework costs incurred in correcting a product failure. In addition, from time to time, specific warranty accruals may be recorded if unforeseen problems arise. Should our actual experience relative to these factors be worse than our estimates, we will be required to record additional warranty expense. Alternatively, if we provide for more reserves than we require, we will reverse a portion of such provisions in future periods. The liability for warranty obligations totaled $8.7 million and $8.6 million at September 30, 2019 and December 31, 2018, respectively, which amounts are included in accrued expenses in the accompanying Condensed Consolidated Balance Sheets. During the three months ended September 30, 2018, we had a reversal of prior provisions, the impact of which is reflected in the table below.

Commitments and Contingencies | 17. COMMITMENTS AND CONTINGENCIES Securities Class Action Lawsuit On October 17, 2019, a purported stockholder class action lawsuit, captioned Burbridge v. ADTRAN, Inc. et al. Other Legal Matters In addition to the litigation described above, from time to time we are subject to or otherwise involved in various lawsuits, claims, investigations and legal proceedings that arise out of or are incidental to the conduct of our business (collectively, “Legal Matters”), including those relating to employment matters, patent rights, regulatory compliance matters, stockholder claims, and contractual and other commercial disputes. Such Legal Matters, even if not meritorious, could result in the expenditure of significant financial and managerial resources. Additionally, an unfavorable outcome in a legal matter, including in a patent dispute, could require the Company to pay damages, entitle claimants to other relief, such as royalties, or could prevent the Company from selling some of its products in certain jurisdictions. While the Company cannot predict with certainty the results of the Legal Matters in which it is currently involved, the Company does not expect that the ultimate outcome of such Legal Matters will individually or in the aggregate have a material adverse effect on its business, results of operations, financial condition or cash flows. Investment Commitment We have committed to invest up to an aggregate of $7.9 million in two private equity funds, of which $7.7 million has been applied as of September 30, 2019. |

Restructuring And Related Activities [Abstract] | |
Restructuring | 18. RESTRUCTURING In October 2019, the Company announced its plans to reduce its operating expenses, including global restructuring. During the three and nine months ended September 30, 2019, the Company incurred approximately $1.1 million and $1.9 million, respectively, related to these plans. In February 2019, we announced the restructuring of certain of our workforce predominantly in Germany, which included the closure of our office location in Munich, Germany accompanied by relocation or severance benefits for the affected employees. We also offered voluntary early retirement to certain other employees, which was announced in March 2019. The restructuring is expected to be completed in the fourth quarter of 2019. In January 2018, we announced an early retirement incentive program for employees that met certain requirements. The cumulative amount incurred during the year ended December 31, 2018 related to this restructuring program was $7.3 million, of which $0.3 million and $7.2 million was incurred during the three and nine months ended September 30, 2018, respectively. We do not expect to incur any additional expenses related to this restructuring program. A reconciliation of the beginning and ending restructuring liability, which is included in accrued wages and benefits in the Condensed Consolidated Balance Sheets, is as follows: Three Months Ended Nine Months Ended (In thousands) September 30, 2019 September 30, 2019 Balance at beginning of period $ 2,655 $ 185 Plus: Amounts charged to cost and expense 1,195 4,658 Less: Amounts paid (252 ) (1,245 ) Balance at end of period $ 3,598 $ 3,598 The components of restructuring expense in the Condensed Consolidated Statements of Income are as follows: Three Months Ended Nine Months Ended September 30, September 30, (In thousands) 2019 2018 2019 2018 Selling, general and administrative expenses $ 531 $ 261 $ 2,078 $ 2,661 Research and development expenses 602 — 1,833 1,814 Cost of sales 62 — 747 2,761 Total restructuring expenses $ 1,195 $ 261 $ 4,658 $ 7,236 The following table represents the components of restructuring expense by geographic area for the three and nine months ended September 30, 2019 and 2018: Three Months Ended Nine Months Ended September 30, September 30, (In thousands) 2019 2018 2019 2018 Domestic $ 1,116 $ 256 $ 1,941 $ 7,096 International 79 5 2,717 140 Total restructuring expenses $ 1,195 $ 261 $ 4,658 $ 7,236 |

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements of ADTRAN ® In the opinion of management, all adjustments necessary to fairly state these interim statements have been recorded and are of a normal and recurring nature. The results of operations for an interim period are not necessarily indicative of the results for the full year. The interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in ADTRAN’s Annual Report on Form 10-K for the year ended December 31, 2018, filed with the SEC on February 28, 2019 (as amended on September 20, 2019, the “2018 Form 10-K”). |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Our more significant estimates include the excess and obsolete inventory reserves, warranty reserves, customer rebates, determination of the deferred and accrued revenue components of multiple performance obligations sales agreements, estimated costs to complete obligations associated with deferred and accrued revenue, estimated income tax provision and income tax contingencies, the fair value of stock-based compensation, impairment of goodwill, valuation and estimated lives of intangible assets, estimated pension liability, fair value of investments and the evaluation of other-than-temporary declines in the value of investments. Actual amounts could differ significantly from these estimates. During the three months ended June 30, 2019, the Company revised the methodology used in estimating its excess and obsolete inventory reserves. Under the revised methodology, we establish reserves for estimated excess and obsolete inventory equal to the difference between the cost of the inventory and the estimated net realizable value of the inventory based on historical usage, known trends, inventory age, and market conditions. When we dispose of excess and obsolete inventories, the related disposals are charged against the inventory reserves. See Note 8 for additional information. |
Correction of Immaterial Misstatements | Correction of Immaterial Misstatements During the three months ended June 30, 2019, the Company determined that there was an immaterial misstatement of its excess and obsolete inventory reserves in its previously issued annual and interim financial statements. The Company corrected this misstatement by recognizing a $0.8 million out-of-period adjustment during the three months ended June 30, 2019, which increased its excess and obsolete inventory reserves and cost of goods sold for the period. For the six months ended June 30, 2019, the out-of-period adjustment was a cumulative $0.2 million reduction in the Company’s excess and obsolete inventory reserves and cost of goods sold. In addition, the Company determined that a $1.0 million cash inflow related to an insurance recovery was incorrectly classified as a cash flow from operations instead of a cash flow from investing activities within the unaudited Condensed Consolidated Statement of Cash Flows for the three months ended March 31, 2019. The Company has corrected this misstatement in the Unaudited Condensed Consolidated Statement of Cash Flows for the nine months ended September 30, 2019 to correctly reflect the $1.0 million insurance recovery as a cash inflow from investing activities. Management has determined that these misstatements were not material to any of its previously issued financial statements and that correction of the misstatements is also not material to the current or estimated annual 2019 financial results on either a quantitative and qualitative basis. |

Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements During 2019, we adopted the following accounting standards, which had the following impacts on our consolidated financial statements: In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), Codification Improvements to Topic 842 Leases Leases (Topic 842), Targeted Improvements Leases (Topic 840) Leases (Topic 842) Codification Improvements The Company adopted the new standard on January 1, 2019, the effective date of our initial application, using the optional transition method. At that time, the Company elected to carry forward the legacy ASC 840 disclosures for comparative periods and, therefore, did not adjust the comparative period financial information prior to January 1, 2019. In addition, the Company elected the package of practical expedients which allows for companies to not reassess whether any expired or existing contracts are or contain leases, not reassess historical lease classifications for expired or existing contracts and not reassess initial direct costs for existing leases. Additionally, the Company elected the practical expedients which allow the use of hindsight when determining the lease term, the short-term lease recognition exemption and the option to not separate lease and non-lease components. The adoption of this standard resulted in the recognition of a right-of-use asset and corresponding right-of-use liability on our Condensed Consolidated Balance Sheet of $10.3 million as of January 1, 2019, primarily related to our operating leases for office space, automobiles and other equipment. As a lessee, the adoption of this standard did not have a material impact on our Condensed Consolidated Statement of Income or Statement of Cash Flows. See Note 12 for additional information. As a lessor, the adoption of this standard did not have a material impact on the Company’s Condensed Consolidated Balance Sheet, Condensed Consolidated Statement of Income or Condensed Consolidated Statement of Cash Flows. Prior to and after adoption, all of our leases in which we are the lessor were classified as sales-type leases. In March 2017, the FASB issued ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (“SOFR”) Overnight Index Swap (“OIS”) Rate as a Benchmark Interest Rate for Hedge Accounting, In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Comprehensive Income.
