Uncertainty +5%
Telecom Maintenance
CATV Maintenance

RY-VA3301 handholdoptical variable attenuator is used for continuously variable opticalsignal attenuation. As the attenuator is used in the laser system forthe on-line testing, there, therefore RY-VA3301 can be used in thedigital 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 theattenuating value and the attenuating step, in order to restore thesystem back to the previous shut down state when open the instrumentsnext time
