LC UPC Flange attenuator
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.
