Overview
GAOTek optical fiber tester 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, VOA-M1 can be used in the digital system of communication devices and in the system of adopting analog modulation (CATV).
Features
- Stepwise attenuating by circumgyrated dial attenuating step 0.05 dB
- Provide with the function of displaying dB and dBm attenuating value
- 10 minutes Auto-off function can be activated
- Deactivate with keypad operation.
- The system will have the memorizing of the attenuating value
- Portable, rugged, lightweight and Easy to use
