Description
Overview
GAOTek Fiber Variable Attenuators are used for continuously variable optical signal attenuation. They are used in the laser system for the online testing, therefore they can be used in the digital system of communication devices (such as: PHD, SDH) and also in the system of adopting analog modulation (CATV).
Features
- Stepwise attenuating by circumgyrate dial: attenuating step 0.05 dB
- Provide with the function of displaying dB and dBm attenuation value
- Alternative function of 10 minutes Auto-off without operation
