BlueOptics Singlemode LC/APC Simplex 9dB Fiber Optic Attenuator

The BlueOptics SFA21BM9 is a high-quality fixed in-line fiber optic attenuator designed for singlemode networks. It provides precise 9dB attenuation with LC/APC connectors in a simplex configuration, ensuring reliable signal reduction in optical communication systems.

Advantages

This attenuator offers excellent return loss (≥60 dB) and low insertion loss repeatability (≤0.2 dB), making it ideal for critical applications. The nickel-plated brass housing and zirconia ceramic ferrule ensure durability and stable performance over 500 matings. It operates across a wide temperature range (-20°C to +70°C) and complies with RoHS and IEC 61754-20 standards.
