Optical Variable Attenuator
Product Introduction
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.
Applications
- Telecom Maintenance
- CATV Maintenance
- Comprehensive cable construction system
- Optical instruments research and development
- Optical communication education and lab testing
- Other optical project
