Variable Optical Attenuator
CARY-VA3301B - UC Instruments, Corp.
The CARY-VA3301B handhold variable optical attenuator is used for continuously variable
optical signal attenuation. Since the variable optical attenuator is used in the laser system for the on-line testing, CARY-VA3301B can be used in the digital system of communication
devices (such as: PHD, SDH) and also can be used in the CATV system testing.
