FV-76903 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, therefore, FV-76903 can be used in the  digital system of communication devices (such as: PHD, SDH) and in the system of adopting analog modulation  (CATV)

➢    Stepwise attenuating by circumgyrated dial: attenuating step 0.05dB

➢    Provide with the function of displaying dB and dBm attenuating value
➢    10 minutes Auto-off function can be activated and deactivated with keypad operation.
➢    After the instrument turned off, the system will record the attenuating value and the step, it will automatically restore to the previous state when restart        the instruments.

➢    Portable, rugged, lightweight.

➢    Easy to use.
