Summary of Significant Accounting Policies	'
	1. Summary of Significant Accounting Policies
	The Company
	Alliance Fiber Optic Products, Inc. (the "Company") was incorporated in California on December 12, 1995 and reincorporated in Delaware on October 19, 2000. The Company designs, manufactures and markets fiber optic components for communications equipment manufacturers. The Company's headquarters are located in Sunnyvale, California, and it has operations in Taiwan and China.
	Basis of Presentation
	The accompanying condensed consolidated balance sheet as of December 31, 2013, which has been derived from audited financial statements, and the unaudited interim condensed consolidated financial statements as of June 30, 2014 and for the three months and six months ended June 30, 2014 have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") and include the accounts of Alliance Fiber Optic Products, Inc. and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations.
	These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013. The unaudited condensed consolidated financial statements as of June 30, 2014, and for the three and six months ended June 30, 2014 and 2013, reflect, in the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to state fairly the financial information set forth herein. The results of operations for the interim periods are not necessarily indicative of the results to be expected for any subsequent interim period or for an entire year.
	There have been no significant changes in the Company's critical accounting policies during the six months ended June 30, 2014 as compared to what was previously disclosed in the Company's Form 10-K for the fiscal year ended December 31, 2013.
	Revenue Recognition
	The Company recognizes revenue upon shipment of its products to customers, provided that it has received a purchase order, the price is fixed, collection of the resulting receivable is reasonably assured and transfer of title and risk of loss has occurred. Subsequent to the sale of products, the Company has no obligation to provide any modification or customization upgrades, enhancements or post contract customer support.
	Allowance for Doubtful Accounts
	Allowances are provided for estimated returns and potential uncollectable trade receivables. Provisions for return allowances are recorded at the time revenue is recognized based on historical returns, current economic trends and changes in customer demand. Such allowances are adjusted periodically to reflect actual and anticipated experience. The Company also identifies specific accounts considered to have a high risk of un-collectability and reserves the full amount. Material differences may result in the amount and timing of revenue for any period than if management had made different judgments or utilized different estimates.
	Cash and Cash Equivalents
	The Company considers all highly liquid instruments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents consist primarily of market rate accounts, corporate bonds, and certificates of deposit.
	Short-Term and Long-Term Investments
	The Company generally invests its excess cash in certificates of deposit and corporate bonds. Such investments are made in accordance with the Company's investment policy, which establishes guidelines relative to diversification and maturities designed to maintain safety and liquidity. These guidelines are periodically reviewed and modified to take advantage of trends in yields and interest rates.
	Concentrations of Risk
	Connectivity products contributed 68.7% and 75.9% of the Company's revenues for the three months ended June 30, 2014 and 2013, respectively. Optical passive products contributed 31.3% and 24.1% of the Company's revenues for the three months ended June 30, 2014 and 2013, respectively.
	Connectivity products contributed 73.8% and 75.1% of the Company's revenues for the six months ended June 30, 2014 and 2013, respectively. Optical passive products contributed 26.2% and 24.9% of the Company's revenues for the six months ended June 30, 2014 and 2013, respectively.
	In the three months ended June 30, 2014 and 2013, the Company's 10 largest customers comprised 77.8% and 72.9% of the Company's revenues, respectively. For the three months ended June 30, 2014, two customers accounted for 34.7% and 15.6% of the Company's revenues, respectively. Amounts due from these customers were $4.8 million and $3.0 million, respectively, at June 30, 2014. For the three months ended June 30, 2013, two customers accounted for 33.3% and 12.8% of the Company's revenues, respectively.
	In the six months ended June 30, 2014 and 2013, the Company's 10 largest customers comprised 78.5% and 70.6% of the Company's revenues, respectively. For the six months ended June 30, 2014, two customers accounted for 42.3% and 11.3% of the Company's revenues.

Recent Accounting Pronouncements	'
	2. Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board ("FASB") issued a new financial accounting standard which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance. The accounting standard is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016. Early adoption is not permitted. The Company is currently evaluating the impact of this accounting standard on its consolidated financial statements.
	In July 2013, the FASB issued guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, similar tax loss or tax carryforward exists. The FASB concluded that an unrecognized tax benefit should be presented as a reduction of a deferred tax asset except in certain circumstances the unrecognized tax benefit should be presented as a liability and should not be combined with deferred tax assets. The amendment is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013, with early adoption permitted. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.
	In March 2013, the FASB issued guidance to clarify when to release cumulative foreign currency translation adjustments when an entity ceases to have a controlling financial interest in a subsidiary or group of assets within a foreign entity. The amendment is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013 and should be applied prospectively to derecognition events occurring after the effective date. Early adoption is permitted. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.
	In February 2013, the FASB issued guidance requiring presentation of amounts reclassified from each component of accumulated other comprehensive income. In addition, disclosure is required of the effects of significant reclassifications on income statement line items either on the face of the statement where net income is presented or as a separate disclosure in the notes to the financial statements. For public entities, this guidance is effective prospectively for reporting periods beginning after December 15, 2012. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.

Stock-based Compensation [Abstract]	'
Stock-based Compensation	'
	3. Stock-based Compensation
	The Accounting Standards Codification ("ASC") 718 requires companies to record compensation expense for stock options measured at fair value, on the date of grant, using an option-pricing model. The fair value of stock options granted and stock purchased pursuant to the Employee Stock Purchase Plan ("ESPP") was determined using the Black-Scholes Model.
	Pursuant to the Company's 2000 Stock Incentive Plan, participants may be granted restricted stock units ("RSUs"), representing an unfunded, unsecured right to receive shares of the Company's common stock on the date specified in the recipient's award. The RSUs granted under the plan generally vest over two years at a rate of 50 percent per year, over three years at a rate of 33.3 percent per year, or over five years at a rate of 20 percent per year. The Company recognizes compensation expense on a straight-line basis over the vesting term of each award.
	Options granted under the 2000 Stock Incentive Plan generally vest over four years. Options are exercisable for not more than ten years.
	The following information relates to stock option activity for the six months ended June 30, 2014:
						Weighted
				Weighted		Average
				Average		Remaining		Aggregate
				Exercise		Contractual		Intrinsic
	Options	Shares		Price		Life		Value
	Outstanding at December 31, 2013	565,640		$	5.28
	Granted	274,400			12.5
	Exercised	(70,340	)		3.51
	Forfeited	(90,000	)		4.45
	Outstanding at June 30, 2014	679,700		$	8.48	8.56 Years		$	6,536,238
	Vested and expected to vest at June 30, 2014	617,760		$	8.43	8.52 Years		$	5,976,085
	Exercisable at June 30, 2014	81,760		$	4.46	5.25 Years		$	1,114,896
	The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company's closing stock price on the last trading day of the second quarter of fiscal 2014 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 June 30, 2014. This amount changes based on the fair market value of the Company's stock. The total intrinsic value of options exercised was $0.7 million and $0.9 million for the three and six months ended June 30, 2014, respectively. The total intrinsic value of options exercised was $2.7 million and $2.8 million for the three and six months ended June 30, 2013, respectively.
	Cash received from option exercises during the six months ended June 30, 2014 and 2013 were $0.2 million and $1.4 million, respectively, and are included within the financing activities section in the accompanying condensed consolidated statements of cash flows.
	During the three months ended June 30, 2014, a total of 21,579 shares were issued under the Company's ESPP and cash received from the purchases was $0.3 million. Compensation expense recorded in the quarter ended June 30, 2014 was $0.1 million. As of June 30, 2014, there was $0.08 million of unrecognized compensation cost related to the ESPP which is expected to be realized over the next four months.
	No options were granted during the three months ended June 30, 2014. Options to purchase 274,400 shares of common stock were granted during the six months ended June 30, 2014. At June 30, 2014, there was $4.0 million of unrecognized compensation cost related to stock options and RSUs, all of which is expected to be realized over three years.
	The following table summarizes employee stock-based compensation expense resulting from stock options, RSUs, and the ESPP (in thousands):
		Three Months Ended				Six Months Ended

	5. Net Income Per Share
	Basic net income per share is computed by dividing net income for the period by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing net income for the period by the combination of dilutive common share equivalents, comprised of shares issuable under the Company's stock-based compensation plans, and the weighted-average number of shares of common stock outstanding during the period. There were no incremental dilutive common share equivalents in the periods presented.
	The following table sets forth the computation of basic and diluted net income per share for the periods indicated (in thousands, except per share data):

	6. Comprehensive Income
	Comprehensive income is defined as the change in equity of a company during a period resulting from transactions and other events and circumstances, excluding transactions resulting from investments by owners and distributions to owners. The difference between net income and comprehensive income for the Company is due to foreign exchange translations adjustments and unrealized loss on available-for-sale securities.

Income Taxes	'
	7. Income Taxes
	The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.
	The Company is subject to income tax in both the United States and various foreign jurisdictions. The effective tax rate is also affected by the taxable earnings in foreign jurisdictions with various different statutory tax rates. The Company reviews its expected annual effective income tax rates and makes changes on a quarterly basis as necessary based on certain factors such as forecasted annual operating income and valuation of deferred tax assets. The Company's effective tax rate was 34.2% and 5.8% for the six months ended June 30, 2014 and 2013, respectively. The Company's effective tax rate for the June 30, 2013 period differs from its expected federal statutory rate primarily as a result of state taxes, foreign tax rate differences, permanent items and the change in valuation allowance.
	The Company records net deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations.
	Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets. The Company reduced deferred tax assets by $2.1 million and $2.8 million for the three and six months ended June 30, 2014 as a result of net operating losses utilized against current taxable income.
	The impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more likely than not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. There have been no material changes in the Company's unrecognized tax benefits since December 31, 2013 and as such, disclosures included in the Company's 2013 Annual Report on Form 10-K continue to be relevant for the period ended June 30, 2014.

	Litigation:
	From time to time, the Company may be involved in litigation in the normal course of business. As of the date of these financial statements, the Company is not aware of any material legal proceedings pending or threatened against the Company.
	Indemnification and Product Warranty:
	The Company indemnifies certain customers, suppliers and subcontractors for attorney fees and damages and costs awarded against these parties in certain circumstances in which products are alleged to infringe third party intellectual property rights, including patents, trade secrets, trademarks or copyrights. In all cases, there are limits on and exceptions to the potential liability for indemnification relating to intellectual property infringement claims. The Company cannot estimate the amount of potential future payments, if any, that it might be required to make as a result of these agreements. As of June 30, 2014, the Company has not paid any claim or been required to defend any action related to indemnification obligations, and accordingly, the Company has not accrued any amounts for such indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations.
	The Company generally warrants products against defects in materials and workmanship and non-conformance to specifications for varying lengths of time. If there is a material increase in customer claims compared with historical experience, or if costs of servicing warranty claims are greater than expected, the Company may record a charge against cost of revenues. The Company accrued $0.1 million and $0.04 million for warranty reserves as of June 30, 2014 and 2013, respectively.
	Operating Leases:
	The Company leases office space under long-term operating leases expiring at various dates through 2018.

	10. Fair Value of Financial instruments
	U.S. GAAP defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which the Company would transact a purchase or sale and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability.
	The Company uses a fair value hierarchy established by U.S. GAAP that established a three-tiered fair value hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable to prioritize inputs used to measure fair value. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's market assumptions. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is available and significant to the fair value measurement. Those tiers are defined as follows:
		Level 1 -	inputs are quoted prices in active markets for identical assets or liabilities.
		Level 2 -	inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly.
		Level 3 -	inputs are unobservable and shall be used to the extent that observable inputs are not available in the overall fair value measurement.
	In accordance with the U.S. GAAP Codification Topic 820, the following table represents the fair value hierarchy for the Company's financial assets (investments) measured at fair value on a recurring basis as of June 30, 2014:
			Fair Value Measurements at
			Reporting Date Using
					Quoted Prices		Significant
					in Active		Other		Significant
