Features
Specifitions
Applications
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.
