In-Line Fixed Attenuators
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 25 dB at intervals of 0.5 dB.
