RY-VA3301A Digital Handheld Optical Variable Attenuator 0~30dB

Introduction:

RY-VA3301 handhold optical variable attenuator is used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for the on-line testing, there, therefore RY-VA3301 can be used in the digital system of communication devices (such as: PHD, SDH) and also in the system of adopting analog modulation (CATV)

Applications:

•Telecom Maintenance
•CATV Maintenance
•Comprehensive cable construction system
•Optical instruments research and development
•Optical communication education and lab testing
•Other optical project

Features

•stepwise attenuating by circumgyrated dial: attenuating step 0.05dB
•Provide with the function of displaying dB and dBm attenuating value
•Alternative function of 10 minutes Auto-off without operation
•After off the instruments, the system will have the memorizing of the attenuating value and the attenuating step, in order to restore the system back to the previous shut down state when open the instruments next time
