Product Description

RUIYAN RY-VA3301A Optical Variable Attenuator

Descriptions

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)
Application
    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
