Description
Overview
GAOTek telecom line testers are used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for online testing, therefore, can be used in the digital system of communication devices (such as: PHD, SDH) and in the system of adopting analog modulation.
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
- Activate and deactivate with keypad operation
- After off the instruments the system will have the memories
- Can restore the attenuating value and the attenuating step
