` dicon?s pm mems attenuator is based on a micro-electro- mechanical system (mems) chip. the mems 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 of the mems attenuator. features small attenuator package high extinction ratio qualified to gr-1221 available in opaque or transparent versions available in both cylindrical and 14-pin dip packages applications 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. u.s. patented. specifications subject to change. copyright ?2004 dicon fiberoptics, inc. all rights reserved. pm mems attenuator attenuators cylindrical package
