FVA-60D 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,
FVA-60D can be used in the digital system of communication devices (such as: PHD, SDH)
and also in the system of adopting analog modulation (CATV)
FVA-60D handhold optical variable attenuator Main Features
stepwise attenuating by circumgyrated dial: attenuating step 0.05dBProvide 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.
FVA-60D handhold optical variable attenuator Applications
Telecom Maintenance.
CATV Maintenance.
Comprehensive cable construction system.
Optical instruments research and development.
Optical communication education and lab testing.
Other optical project.
