PM
MEMS OPTICAL AT TENUATOR
DiCon’s PM MEMS Optical Attenuator is based on a micro-
electro-mechanical system (MEMS) chip. The PM MEMS chip
consists of an electrically movable mirror on a silicon support. A
voltage applied to the PM MEMS chip causes the mirror to rotate,
which changes the coupling of light between the input and output
fibers of the PM MEMS Optical Attenuator.

APPLICATIONS
PM MEMS Optical Attenuators are used for distributed power
equalization within OADMs, MUX/DMUXes, Band Equalizers,
Channel Equalizers, Optical Cross-Connects, Line Cards and
Transponders. Polarization Maintaining Optical Attenuators can also
be used for power adjustment in polarization sensitive devices such
as modulators.
