Description
Overview
GAOTek handheld variable optical tester (VOA-M1) allows for continuous adjustment of optical signal attenuation. Primarily used in laser systems for online testing, it is compatible with digital communication devices (e.g., PHD, SDH) and analog modulation systems.
Features
- Stepwise attenuating
- Displaying dB and dBm attenuating value
- Auto-off function
- Memorizing of the attenuating value
