Adjustable fiber optic attenuators typically cost between $5 and $50 per piece, depending on type, connector, and supplier.

Adjustable fiber optic attenuators are used to precisely control optical signal strength in single-mode or multi-mode fiber systems. Prices vary based on attenuation range, connector type (FC, SC, LC, ST), and quality. For example, a single-mode FC/UPC adjustable attenuator with a 1–30dB range can cost around $5 per piece when purchased from suppliers like Made-in-China, though shipping and bulk orders may affect the final price . On platforms like Alibaba, adjustable attenuators are available in various types (manual screw-type, digital, stepped) and prices can range from $5 to $50 or more, depending on precision, brand, and order quantity . Retailers such as Amazon and DigiKey also offer fiber optic attenuators, often at slightly higher prices due to shipping and retail markup . Factors influencing cost include:

• Attenuation range: Wider ranges (e.g., 1–30dB) may be slightly more expensive.
• Connector type: FC, SC, LC, or ST connectors can affect compatibility and price.
• Build quality: High-precision, low return-loss models for lab or telecom use are more costly.
• Quantity: Bulk purchases often reduce per-unit cost. In summary, for most standard applications, expect to pay $5–$50 per adjustable fiber optic attenuator, with higher-end or specialized models costing more. For precise lab or telecom deployments, investing in quality attenuators ensures reliability, repeatability, and low signal loss .
