Product Detail Information


Multimode MEMES 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.
We offers the best value of miniature VOA product that is competitive with other VOA
