BlueOptics Fiber Optic Attenuator Singlemode LC/APC Simplex 6dB

The BlueOptics SFA21BM6 is a high-quality fiber optic attenuator designed for singlemode networks. It provides a precise 6 dB attenuation to optimize signal levels and prevent receiver overload. With LC/APC connectors and a simplex configuration, this attenuator ensures low insertion loss and high return loss, making it ideal for FTTH, CATV, and telecommunication applications.

Advantages

This attenuator offers reliable performance with a wide wavelength range of 1260-1650 nm, ensuring compatibility with various singlemode systems. Its nickel-plated brass housing and zirconia ceramic ferrule provide durability and stable optical performance over many mating cycles. The angled physical contact (APC) polish minimizes back reflection, enhancing signal integrity.
