MEMS ATTENUATOR DiCon's 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 n n n n Small attenuator package Based on DiCon's proven MEMS platform Available in opaque or transparent versions Qualified to GR-1221 APPLICATIONS MEMS Attenuators 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 erbiumdoped fiber amplifiers. Specifications subject to change. Copyright (c) 2010 DiCon Fiberoptics, Inc. All rights reserved.
