MEMS VOA (Variable Optical Attenuator)

| DESCRIPTION

MEMS Variable Optical Attenuator is based on a micro-electro-mechanical system featuring compact
design, easy direct drive, and excellent optical performance.
The MEMS VOAs are used for distributed power equalization within ROADMs, MUX/DEMUX, Band
Equalizers, Channel Equalizers, Optical Cross-Connects, Line Cards and Transponders.
MEMS VOAs can be applied for all optical fields requiring input power adjustments of optical signals.
