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. Product Facts LEDSOPTIC offers air-gap Bulkhead-type Fixed Value Attenuator suitable for 850nm or 1310nm or 1550nm. Available in FC ( Square Type) , SC ( Flange Type) and ST ( Thread Type) types.
