Description
Overview
GAOTek Light Fibre 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 (such as: PHD, SDH) and also in the system of adopting analogy modulation.
Features
- stepwise attenuating by circumgyrated dial
- Provide with the function of displaying dB and dBm value
- 10 minutes Auto-off function can be activated
- The system will have the memorizing of the attenuating value
- To restore the system back to the previous shut down
- Portable, rugged, lightweight; Easy to use
- Telecom Maintenance
- CATV Maintenance
- Comprehensive cable construction system
- Optical instruments research and development
- Optical communication education and lab testing
