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.


  • Small attenuator package
  • Qualified to GR-1221
  • Available in opaque or transparent versions
  • Available in both cylindrical and 14-pin DIP packages


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 erbium-doped fiber amplifiers.
