Cash And Cash Equivalents	Cash and Cash Equivalents All of the Company’s bank accounts are insured by the Federal Deposit Insurance Corporation (FDIC). As of October 31, 2013, the Company had bank deposits in excess of the insured limit totaling $405,232. As of October 31, 2012, all of the Company’s bank deposits were insured.

Trade Accounts Receivable And Allowance For Doubtful Accounts	Trade Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount and do not typically bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company reviews outstanding trade accounts receivable at the end of each quarter and records allowances for doubtful accounts as deemed appropriate for (i) certain individual customers and (ii) for all other trade accounts receivable in total. In determining the amount of allowance for doubtful accounts to be recorded for individual customers, the Company considers the age of the receivable, the financial stability of the customer, discussions that may have occurred with the customer and management’s judgment as to the overall collectibility of the receivable from that customer. In addition, the Company establishes an allowance for all other receivables for which no specific allowances are deemed necessary. This portion of the allowance for doubtful accounts is based on a percentage of total trade accounts receivable with different percentages used based on different age categories of receivables. The percentages used are based on the Company’s historical experience and management’s current judgment regarding the state of the economy and the industry. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers.
Inventories	Inventories Inventories are stated at the lower of cost or market, or net realizable value. The determination of cost includes raw materials, direct labor and manufacturing overhead. The cost of optical fibers, included in raw materials, is determined using specific identification for optical fibers. The cost of other raw materials and production supplies is generally determined using the first-in, first-out basis. The cost of work in process and finished goods inventories is determined either as average cost or standard cost, depending upon the product type. A standard cost system is used to estimate the actual costs of inventory for certain product types. Actual costs and production cost levels may vary from the standards established and such variances are charged to cost of goods sold or capitalized to inventory. Also see note 3.
Property And Equipment	Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided for using both straight-line and declining balance methods over the estimated useful lives of the assets. Estimated useful lives are thirty to thirty-nine years for buildings and three to seven years for building improvements, machinery and equipment and furniture and fixtures. Also see note 4.
Patents And Trademarks	Patents and Trademarks The Company records legal fees associated with patent and trademark applications as intangible assets. Such intangible assets are not amortized until such time that the patent and/or trademark is granted. The Company estimates the useful life of patents and trademarks based on the period over which the intangible asset is expected to contribute directly or indirectly to future cash flows. If patents and/or trademarks are not granted, the capitalized legal fees are expensed during the period in which such notification is received.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when products are shipped or delivered to the customer and the customer takes ownership and assumes risk of loss (based on shipping terms), collection of the relevant receivable is probable, persuasive evidence of an arrangement exists and sales price is fixed or determinable. Customers generally do not have the right of return unless a product is defective or damaged and is within the parameters of the product warranty in effect for the sale. The Company recognizes royalty income, net of related expenses, on an accrual basis and estimates royalty income earned based on historical experience.
Shipping And Handling Costs	Shipping and Handling Costs Shipping and handling costs include the costs incurred to physically move finished goods from the Company’s warehouse to the customers’ designated location. All amounts billed to a customer in a sales transaction related to shipping and handling are classified as sales revenue. Shipping and handling costs of approximately $2.2 million, $2.6 million and $2.2 million are included in selling, general and administrative expenses for the fiscal years ended October 31, 2013, 2012 and 2011, respectively.
Research And Development	Research and Development Research and development costs are expensed as incurred. Research and development costs totaled approximately $1.4 million, $1.3 million and $1.1 million for the fiscal years ended October 31, 2013, 2012 and 2011, respectively, and are included in selling, general and administrative expenses in the consolidated statements of operations.

Advertising costs totaled approximately $546,000, $741,000 and $570,000 for the fiscal years ended October 31, 2013, 2012 and 2011, respectively, and are included in selling, general and administrative expenses in the consolidated statements of operations.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss, capital loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest and penalties related to unrecognized tax benefits as a component of income tax expense. Also see note 12.
Long-Lived Assets	Long-Lived Assets Long-lived assets, such as property and equipment and acquired intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. When applicable, assets to be disposed of are reported separately in the consolidated balance sheet at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated.
