Handheld Fibre Optical Attenuator allows continuous optical signal attenuation up to 60dB with precise 0.05dB step adjustments.
Description
Description
Overview
GAOTek handheld fibre 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, this device can be used in the digital system of communication devices (such as: PHD, SDH) and in the system of adopting analogue modulation (CATV).
Features
- Stepwise attenuation by circumgyrated dial: 0.05 dB steps
- Displays dB and dBm attenuating values
- 10-minute auto-off function, activated/deactivated with keypad
- Memorizes attenuating value and step for system restoration
- Displays dB and dBm attenuating values
