MU/PC attenuator

Fiber optic attenuators are devices that reduces signal power in fiber optic links by fixed loss.
Fiber Attenuators are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters.
Fiber Attenuators are also used to test the linearity and dynamic range of photo sensors and photo detectors.
