动态可调光衰减器 MEMS VOA光衰减器
Product Description
L-series VOA is a VOA product family using the MEMS chip with a movable mirror on the silicon. The mirrorattenuates the laser light power by coupling the input beam onto the output fiber. The applied voltageto the device controls the mirr
or tilt angle, thus the desired attenuation amount.
微机电可调光衰减器 MEMS VOA 是一种新型的低成本、小体积的电磁驱动微机电系统可调
光衰减器 , 可用于密集波分复用系统中各信道的动
态增平衡。
