Adaptor Type Fixed Attenuator

A fiber optic attenuator is a passive device used to reduce the amplitude of a light signal without significantly changing the wave form itself. This is often a requirement in Dense Wave Division Multiplexing ( DWDM) and Erbium Doped Fiber Amplifier ( EDFA) applications where the receiver cannot accept the signal generated from a high-power light source.
