PM MEMS ATTENUATOR DiCon's PM MEMS Attenuator is based on a micro-electromechanical system (MEMS) chip.The PM MEMS chip consists of an electrically movable mirror on a silicon support. A voltage applied to the PM MEMS chip causes the mirror to rotate, which changes the coupling of light between the input and output fibers of the PM MEMS Attenuator. FEATURES n n n n n Small attenuator package Based on DiCon's proven MEMS platform Available in opaque or transparent versions Qualified to GR-1221 High Extinction Ratio APPLICATIONS PM MEMS Attenuators are used for distributed power equalization within OADMs, MUX/DMUXes, Band Equalizers, Channel Equalizers, Optical Cross-Connects, Line Cards and Transponders. Polarization Maintaining Attenuators can also be used for power adjustment in polarization sensitive devices such as modulators. Specifications subject to change.
