Fiber optic attenuators typically range from $5 to $100+ depending on type, connector, and attenuation level.

Price Overview by Vendor

• FS (Fiberstore): Offers fixed and variable attenuators with attenuation ranges from 0 to 60 dB. Prices vary based on connector type (SC, FC, LC, ST) and attenuation value, generally starting around $10–$50 per unit for standard single-mode attenuators .
• Mouser Electronics: Provides a wide selection of fiber optic attenuators with inventory, datasheets, and pricing. Entry-level fixed attenuators can start at $5–$15, while higher-precision or specialty models may exceed $50 .
• DigiKey: Stocks single-mode, dual-window, and multimode attenuators with various connector types (FC, SC, ST, MU). Prices typically range from $7 for basic fixed attenuators to $80+ for high-precision or variable models .
• Amazon: Offers industrial and scientific fiber optic attenuators at everyday low prices, often in the $10–$60 range, depending on brand and specifications .
• Made-in-China: Lists factory-priced optical fiber attenuators, suitable for bulk or OEM purchases. Prices can be negotiated for wholesale orders, often lower than retail, with options for custom designs and higher attenuation ranges .

Factors Affecting Price

1. Attenuation Type: Fixed attenuators are generally cheaper than variable attenuators.
2. Connector Type: SC, FC, LC, ST, and APC variants can influence cost.
3. Mode Compatibility: Single-mode attenuators are usually more expensive than multimode.
4. Precision and Tolerance: High-precision attenuators with tight dB tolerances cost more.
5. Quantity: Bulk or OEM orders often reduce per-unit cost.

Recommendations

• For small-scale or individual use, Amazon, DigiKey, or Mouser provide convenient options with transparent pricing.
• For bulk or OEM procurement, consider FS or Made-in-China for factory pricing and customizable specifications.
• Always compare multiple vendors to ensure competitive pricing and check datasheets for compatibility with your fiber optic system. This overview provides a current market snapshot of fiber optic attenuator prices and purchasing options, helping you make informed procurement decisions.
