MEMS ATTENUATOR / ON-OFF SWITCH DiCon's Attenuator/On-Off Switch is based on a micro-electromechanical 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 Attenuator/ On-Off Switch. 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 Combines Variable Optical Attenuator and On-Off Switch APPLICATIONS Attenuator/On-Off Switches are used as safety shutters during laser transmitter power up as well as for channel equalization once the laser has stabilized. In its highest loss position, the Attenuator/ On-Off Switch provides greater than 45 dB of power isolation. Used as an Attenuator, it allows the output power of the laser to be continuously adjusted over a 40 dB range. Attenuator/On-Off Switches are ideally suited for use within line cards or transponders.
