Attenuators
Multi-Channel MEMS Attenuator Module
C
DiCon’s Multi-Channel MEMS Attenuator Module consists of an
array of 8 or less MEMS Attenuator components which are
used for multi-channel attenuation. DiCon’s MEMS Attenuator
is based on a micro-electro-mechanical system (MEMS) chip.
Multi-Channel MEMS Attenuator Modules create a significant
reduction in the amount of board space which needs to be
dedicated to attenuation.

Applications
Multi-Channel MEMS Attenuator
Modules are used to attenuate power
levels for multiple wavelength channels or bands. Primary applications
include dynamic gain equalizers, DWDM and MUX/DMUX module power
level control.
