What is the price of an adjustable optical attenuator

Adjustable optical attenuators typically range from $17 to over $500 depending on type, attenuation range, and vendor.Price OverviewOnline retail prices for adjustable fiber optic attenuators vary widely based on specifications:Entry-level mechanical variable attenuators (0–30 dB, single-mode/multi-mode) are available for $17–$55 on platforms like FS, Amazon, and Walmart .Clip-on or air-gap variable attenuators for testing or lab use typically cost $60–$180 .High-precision or MEMS-based variable attenuators with wider ranges (up to 60 dB) or specialized features can range from $138 to $259, suitable for professional or DWDM applications .Premium or benchtop variable attenuator kits for laboratory or industrial use may exceed $500, offering precise control, low return loss, and high stability .Factors Affecting PriceAttenuation Range: Wider ranges (e.g., 0–60 dB) generally cost more than standard 0–30 dB units.Connector Type: LC, SC, FC, and APC connectors can influence cost; APC versions often carry a premium.Fiber Mode: Single-mode attenuators are typically more expensive than multimode due to higher precision requirements.Technology: Mechanical, MEMS, or motorized attenuators differ in price, with MEMS and motorized units being more costly.Quantity and Packaging: Bulk packs or multi-packs can reduce per-unit cost, while single units may be slightly higher .Recommended RetailersAmazon: Offers a wide range of adjustable attenuators from $17 to $259, including mechanical and MEMS types .DigiKey: Focused on professional-grade attenuators, prices from $138 to $375 for MEMS or ultra-mini variable attenuators .FS.com: Provides both mechanical and high-precision variable attenuators, ranging from $17 to $149 .eBay: Offers new and used attenuators, with prices from $20 to $490 depending on condition and specifications .Walmart: Entry-level adjustable attenuators around $19–$50 for single-mode/multi-mode applications .Specialized suppliers (OZ Optics, Fiber Instrument Sales, Fosco Connect) provide custom or high-performance attenuators, often requiring a quote for exact pricing .SummaryFor most standard single-mode adjustable optical attenuators, expect to pay $17–$55 for mechanical units suitable for general fiber optic applications. Professional or MEMS-based attenuators for precise laboratory or DWDM use can range from $138 to $500+. Prices vary based on attenuation range, connector type, fiber mode, and technology, so selecting the right type for your application is essential.
