Continuously Variable Attenuators,FC Variable Optical Fiber Attenuator

FC Variable Optical Fiber Attenuator

Fiber optic attenuator is used for reducing the power of the light in the fiber optic network.

Variable fiber optic attenuator could help simulate distance or actual attenuation in the fiber optic testing work by inserting a calibrated attenuation into the link. Important parameters of variable fiber attenuator include its insertion loss, reflection loss and attenuation range.
