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.
