Product Description

Low PDL WDM System MEMS Variable Optical Attenuator

Gezhi Photonics MEMS attenuators (MEMS VOAs) are based on a micro-electro-mechanical system (MEMS) technology. The MEMS attenuators design achieves highly repeatable optical attenuation over C and/or L band through an electrically movable mirror on silicon.

Product Features

Low insertion loss
Low polarization dependent
Compact size
Available in both normally open and normally closed states
Excellent reliability

Product Application

Power Management
Receiver protective
Channel Balance
Instrumentation
