  • Thông tin chi tiết
    • RY-VA3301 handheld 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
