PM MEMS ATTENUATOR
DiCon’s PM MEMS 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 Attenuator.

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