Optical Variable Attenuator JW3303

JW3303 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, JW3303 can be used in the digital system of communication devices (such as: PHD, SDH) and also in the system of adopting analog modulation (CATV)

Main 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.

Applications:

Telecom Maintenance
CATV Maintenance
Comprehensive cable construction system
Optical instruments research and development
Optical communication education and lab testing
Other optical project
