Variable optical attenuator
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 photodetector to within the limits of the optical receiver.
Features: High Precise attenuation value Perfect environmental stability and reliability Low additional loss Flawless end face Wide attenuation range (variable)
Application: Fiber optical telecommunication system FTTH, CATV, LAN Subscriber loop Fiber optical sensor Testing equipment
