Available in opaque or transparent versions
Qualied to GR-1221
High Extinction Ratio
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.
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 bers of the PM
MEMS Attenuator.
