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.
Features:
Low back reflection and Low PDL
High precision attenuation value
Precision control of attenuation range
Wide attenuation range
Precision ceramic ferrule
FC, SC, ST, LC ^ optional
Plastic or metal housing material
Application:
Fiber optical telecommunication system
Fiber optical CATV
Fiber optical sensor
Testing equipment.
