In-Line Fixed Fused PM Fiber Attenuator

In-Line Fixed Attenuators are mainly used for adjusting the Optical Power to a desired level. We manufacture our attenuators with various specifications such as different connector types or end face configurations. The Attenuation Level in dB ranges from 0dB to 40 dB at intervals of 0.5 dB.
