BlueOptics Fiber Optic Attenuator Singlemode LC/APC Simplex 20 dB

The BlueOptics SFA21BM20 is a high-quality fiber optic attenuator designed for singlemode networks. It provides a precise 20 dB attenuation to optimize signal levels and prevent receiver overload in telecommunications, data centers, FTTx, LAN, and CATV applications. The LC/APC connector ensures low insertion loss and high return loss, making it ideal for high-performance optical systems.

Advantages

This attenuator offers reliable and stable attenuation with a tolerance of ±0.5 dB, ensuring consistent performance. The APC polish minimizes back reflection, and the durable metal alloy housing with zirconia ceramic ferrule guarantees long-term reliability over 500 mating cycles. It is RoHS and CE compliant, meeting industry standards for safety and environmental responsibility.
