BlueOptics Singlemode LC/APC Simplex Fiber Optic Attenuator 1 dB

The BlueOptics SFA21BM1 is a high-quality singlemode fiber optic attenuator designed to reduce optical power in fiber optic networks. With a precise attenuation of 1 dB and LC/APC connectors, this simplex attenuator ensures reliable signal management in telecommunications, data centers, and FTTx applications. Manufactured with a zirconia ceramic ferrule and metal housing, it offers durability and consistent performance over more than 1000 mating cycles.

Advantages

This attenuator provides accurate and stable attenuation with a tolerance of ±0.5 dB, ensuring optimal signal levels. The angled physical contact (APC) polish minimizes back reflection, with a return loss of ≥60 dB, making it ideal for high-performance networks. Its wide operating temperature range (-40°C to +85°C) guarantees reliability in various environments.
