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.

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 erbium-
doped fiber amplifiers.
