电控可调光衰减器 MEMS VOA

L-series VOA is a VOA product family using the MEMS chip with a movable mirror on the silicon. The mirror

attenuates the laser light power by coupling the input beam onto the output fiber. The applied voltage

to the device controls the mirror tilt angle, thus the desired attenuation amount.
