Extra small size
MOA100 was based on MEMS process. The chip consists of an electrically movable mirror on a silicon support. A voltage applied to the MEMS chip causes the mirror to rotate, which changes the coupling of light between the input and output fibers is the MEMS attenuator.
MOA100 MEMS attenuator chip are used for distributed power equalization within OADMs, MUX/DMUXes, Band Equalizers, Channel Equalizers, Optical Cross-Connects, Line Cards and Transponders. MEMS Attenuators can also be used for input power adjustment in erbium-doped fiber amplifiers.
