JT3303 handhold optical variable attenuator is used for continuously variable optical signal attenuation.

JT3303 handheld optical variable attenuator

Description:

JT3303 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, JT3303 can be used in the digital system of communication devices (such as: PHD, SDH) and also in the system of adopting analog modulation (CATV)

Optical Variable Attenuator

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
