Product Description

General information

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)

Key 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, r ed, lightweight; Easy to use.
