Description
Overview
GAOTek telecom line tester is used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for the on-line 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
- Auto-save settings for seamless restart on power-up
