MEMS optical attenuator module is a device used to attenuate optical power. It is mainly used for index measurement of optical fiber systems, signal attenuation of short-distance communication systems, and system testing. The optical attenuator is a very important fiber optic passive device. It can attenuate the optical signal energy as expected according to the user’s requirements. It is often used to absorb or reflect the optical power margin, evaluate the loss of the system and various tests. . At present, this series of optical attenuators has been widely used in the field of optical communications.
