This 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, it can be used
in the digital system of communication devices (such as: PHD, SDH)
and also in the system of adopting analog modulation (CATV)
Features
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 activate and deactivate with
keypad 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
Portable, rugged, lightweight; Easy to use.
