VOA is a useful tool for the optical components and systems test. the Manual Variable Optical Attenuator is designed and manufactured to reduce the output optical power, get the power suitable. It is with low insertion loss, high extinction ration, high return loss and low Adjustment Precision, The Attenuator is widely applied at fiber laser, fiber CWDM/DWDM/OADM communication system, they can be used for power control and equalization for WDMs, FTTx, CATV and Test & Measurement instruments.
