Product Description

Fiber Optical Attenuator with FC / SC / ST / LC Connector optional


Fiber Optic Attenuator is a component installed in a fiber optic transmission system that reduces the power in the optical signal. It is often used to limit the optical power received by the photo detector to within the limits of the optical receiver. Sopto can provide female to male (plug type), Bulkhead-fixed value attenuator, in-line attenuator and variable attenuators.
