Notes to Financial Statements
Share-Based Payment Arrangement [Text Block]	(2) Stock Incentive Plans and Other Share Based Compensation On March 29, 2022, the Company’s shareholders approved the First Amendment (the “First Amendment”) to the Optical Cable Corporation 2017 Stock Incentive Plan (the “2017 Plan”) that was recommended for approval by the Company’s Board of Directors. The First Amendment reserves an additional 350,000 common shares of the Company for issuance under the 2017 Plan. As a result, there were approximately 355,000 shares available for grant under the 2017 Plan as of April 30, 2022 (including the 350,000 new shares added to the 2017 Plan). Share-based compensation expense for employees, a consultant and non-employee Directors recognized in the condensed consolidated statements of operations for the three months and six months ended April 30, 2022 was $113,212 and $237,651, respectively, and for the three months and six months ended April 30, 2021 was $101,762 and $142,367, respectively. Share-based compensation expense is entirely related to expense recognized in connection with the vesting of restricted stock awards or other stock awards. Stock Compensation The Company has granted, and anticipates granting from time to time, restricted stock awards subject to approval by the Compensation Committee of the Board of Directors. Since fiscal year 2004, the Company has exclusively used restricted stock awards for all share-based compensation of employees and consultants, and restricted stock awards or stock awards to non-employee members of the Board of Directors. The restricted stock awards granted to employees under the 2017 Plan vest over time if certain operational performance-based criteria are met. Failure to meet the criteria required for vesting will result in a portion or all of the shares being forfeited. During the three months ended April 30, 2022, a restricted stock award for an employee under the 2017 Plan totaling 17,500 shares were approved by the Compensation Committee of the Board of Directors of the Company. All of the restricted shares granted are operational performance-based shares vesting over approximately four During the three months ended April 30, 2022, OCC also granted restricted stock awards totaling 27,364 shares to non-employee Directors under the 2017 Plan. The shares are subject to a one-year Restricted stock award activity during the six months ended April 30, 2022 consisted of restricted stock grants totaling 44,864 shares, restricted shares forfeited totaling 25,313 shares and restricted shares withheld for taxes in connection with the vesting of restricted shares totaling 22,166. OCC restricted stock grants provide the participant with the option to surrender shares to pay for withholding tax obligations resulting from any vesting restricted shares, or to pay cash to the Company or taxing authorities in the amount of the withholding taxes owed on the value of any vesting restricted shares in order to avoid surrendering shares. As of April 30, 2022, the estimated amount of compensation cost related to unvested equity-based compensation awards in the form of service-based and operational performance-based shares that the Company will recognize over a 3.5 year weighted-average period is approximately $1.2 million.

Note 7 - Leases

Note 7 - Leases	Apr. 30, 2022
Notes to Financial Statements
Lessee, Operating and Finance Leases Disclosure [Text Block]	(7) Leases The Company has an operating lease agreement for approximately 34,000 square feet of office, manufacturing and warehouse space in Plano, Texas (near Dallas). The lease term expires on November 30, 2024. The Company has an operating lease agreement for approximately 36,000 square feet of warehouse space in Roanoke, Virginia. The lease term expires on April 30, 2023. The Company also leases certain office equipment under operating leases with initial 60 month terms. The lease terms expire in February and April of 2025. OCC leases printers that are used in the Roanoke, Virginia manufacturing facility. The lease term expires on August 22, 2026. The right-of-use asset is being amortized on a straight line basis over seven years. When the lease term ends, the remaining net book value of the right-of-use asset will be classified as property and equipment. The Company’s lease contracts may include options to extend or terminate the leases. The Company exercises judgment to determine the term of those leases when such options are present and include such options in the calculation of the lease term when it is reasonably certain that it will exercise those options. The Company includes contract lease components in its determination of lease payments, while non-lease components of the contracts, such as taxes, insurance, and common area maintenance, are expensed as incurred. At commencement, right-of-use assets and lease liabilities are measured at the present value of future lease payments over the lease term. The Company uses its incremental borrowing rate based on information available at the time of lease commencement to measure the present value of future payments. Operating lease expense is recognized on a straight-line basis over the lease term. Short term leases with an initial term of 12 months or less are expensed as incurred. The Company’s short term leases have month-to-month terms.

Note 9 - Net Income (Loss) Per Share	Apr. 30, 2022
Notes to Financial Statements
Earnings Per Share [Text Block]	Net Income (Loss) Per Share Basic net income (loss) per share excludes dilution and is computed by dividing net income (loss) available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted net income (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the net income (loss) of the Company. The following is a reconciliation of the numerators and denominators of the net income (loss) per share computations for the periods presented: Three months ended Six months ended April 30, April 30, 2022 2021 2022 2021 Net income (loss) (numerator) $ (227,991 ) $ 3,385,159 $ (1,163,784 ) $ 1,243,679 Shares (denominator) 7,487,337 7,536,116 7,464,862 7,536,121 Basic and diluted net income (loss) per share $ (0.03 ) $ 0.45 $ (0.16 ) $ 0.17 Weighted average unvested shares for the three months and six months ended April 30, 2022 totaling 373,751 and 403,114, respectively, while issued and outstanding, were not included in the computation of basic and diluted net loss per share for the three months and six months ended April 30, 2022 (because to include such shares would have been antidilutive, or in other words, to do so would have reduced the net loss per share for those periods).

Note 11 - Revenue Recognition

Note 11 - Revenue Recognition	Apr. 30, 2022
Notes to Financial Statements
Revenue from Contract with Customer [Text Block]	(11) Revenue Recognition Revenues consist of product sales that are recognized at a specific point in time under the core principle of recognizing revenue when control transfers to the customer. The Company considers customer purchase orders, governed by master sales agreements or the Company’s standard terms and conditions, to be the contract with the customer. For each contract, the promise to transfer the control of the products, each of which is individually distinct, is considered to be the identified performance obligation. The Company evaluates each customer’s credit risk when determining whether to accept a contract. In determining transaction prices, the Company evaluates whether fixed order prices are subject to adjustment to determine the net consideration to which the Company expects to be entitled. Contracts do not include financing components, as payment terms are generally due 30 to 90 days after shipment. Taxes assessed by governmental authorities and collected from the customer including, but not limited to, sales and use taxes and value-added taxes, are not included in the transaction price and are not included in net sales. The Company recognizes revenue at the point in time when products are shipped or delivered from its manufacturing facility to its customer, in accordance with the agreed upon shipping terms. Since the Company typically invoices the customer at the same time that performance obligations are satisfied, no contract assets are recognized. The Company’s contract liability represents advance consideration received from customers prior to transfer of the product. This liability was $221,194 as of April 30, 2022 and $308,406 as of October 31, 2021. Sales to certain customers are made pursuant to agreements that provide price adjustments and limited return rights with respect to the Company’s products. The Company maintains a reserve for estimated future price adjustment claims, rebates and returns as a refund liability. The Company’s refund liability was $128,343 as of April 30, 2022 and $159,125 as of October 31, 2021. The Company offers standard product warranty coverage which provides assurance that its products will conform to contractually agreed-upon specifications for a limited period from the date of shipment. Separately-priced warranty coverage is not offered. The warranty claim is generally limited to a credit equal to the purchase price or a promise to repair or replace the product for a specified period of time at no additional charge. The Company accounts for shipping and handling activities related to contracts with customers as a cost to fulfill its promise to transfer control of the related product. Shipping and handling costs are included in selling, general and administrative expenses in the accompanying Condensed Consolidated Statements of Operations. The Company incurs sales commissions to acquire customer contracts that are directly attributable to the contracts. The commissions are expensed as selling expenses during the period that the related products are transferred to customers. Disaggregation of Revenue The following table presents net sales attributable to the United States and all other countries in total for the three months and six months ended April 30, 2022 and 2021: Three months ended Six months ended April 30, April 30, 2022 2021 2022 2021 United States $ 14,792,289 $ 12,381,735 $ 26,936,668 $ 22,085,345 Outside the United States 2,408,289 3,359,379 4,704,205 5,532,342 Total net sales $ 17,200,578 $ 15,741,114 $ 31,640,873 $ 27,617,687

Note 12 - Employee Retention Tax Credit	Apr. 30, 2022
Notes to Financial Statements
Employee Retention Tax Credit [Text Block]	(12) Employee Retention Tax Credit The Employee Retention Tax Credit (“ERTC”), created in the March 2020 CARES Act and then subsequently amended by the Consolidated Appropriation Act (“CAA”) of 2021, the American Rescue Plan Act (“ARPA”) of 2021 and the Infrastructure Investment and Jobs Act (“IIJA”) of 2021, is a refundable payroll credit for qualifying businesses keeping employees on their payroll during the COVID-19 pandemic. Under CAA, ARPA and IIJA amendments, employers can claim a refundable tax credit against the employer share of social security tax equal to 70% of the qualified wages (including certain health care expenses) paid to employees after December 31, 2020 through September 30, 2021. Qualified wages were limited to $10,000 per employee per calendar quarter in 2021 so the maximum ERTC available was $7,000 per employee per calendar quarter. OCC is an eligible small employer under the gross receipts decline test when comparing the first calendar quarter of 2021 to the same quarter in calendar year 2019, which qualified the Company to claim ERTC in both the first and second calendar quarters of 2021 under the amended ERTC program. The Company qualified for a refundable payroll tax credit totaling $3,375,815 during its second fiscal quarter and $964,550 during its third fiscal quarter of 2021 for a total of $4,340,365. There is $2,162,391 of the ERTC remaining in other receivables on the Company’s condensed consolidated balance sheet as of April 30, 2022. Subsequent to April 30, 2022, the remaining ERTC receivable was received by the Company.

Note 13 - Contingencies	Apr. 30, 2022
Notes to Financial Statements
Commitments and Contingencies Disclosure [Text Block]	(13) Contingencies From time to time, the Company is involved in various claims, legal actions and regulatory reviews arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Company’s financial position, results of operations or liquidity. The COVID-19 pandemic has had a significant impact on businesses and individuals in the United States and globally. Actions taken by governments and private industry to limit the spread of the disease (including its variant strains) have resulted in an unprecedented disruption of normal activities as businesses have been forced to shut down or operate on a limited basis. The Company is obligated and continues to operate during the COVID-19 pandemic because the Company’s workforce is classified a “Defense Industrial Base Essential Critical Infrastructure Workforce” under guidelines from the U.S. Department of Defense and an “Essential Critical Infrastructure Workforce” under guidelines by the U.S. Department of Homeland Security, Cybersecurity and Infrastructure Security Agency (CISA). In response to the changing dynamics of the COVID-19 pandemic and endemic, the Company continues to focus on employee well-being so it closely monitors the Centers for Disease Control and Prevention recommendations and community levels for each of its facilities in order to react quickly with appropriate safety protocols such as increased masking and/or social distancing as warranted. The extent to which the COVID-19 pandemic will directly and indirectly affect the Company in the future will depend on ongoing developments, which are highly uncertain and cannot be reasonably predicted, including, but not limited to, the duration and severity of future outbreaks; the timing and extent of the imposition or easing of restrictions on businesses and individuals in various markets; the impact on product demand in certain of the Company’s markets; the potential for a resurgence of the virus (including its variant strains); supply chain and labor constraints impacting production volumes and costs directly or indirectly resulting from the pandemic and after effects of the pandemic; as well as a variety of other unknowable factors. The longer the various direct and indirect impacts of COVID-19 persist, the greater the potential negative financial effects on the Company.
