MEMS Variable Optical Attenuator

UVOA Series

Oplink’s MEMS (Micro-Electro-Mechanical Systems) Variable Optical Attenuator

(μVOA) uses an electrostatic tilting mirror to change light coupling between input

and output fibers. Key features include low IL, fast response and compact size.

μVOA is available in Dark or Bright type. Applications include power equalization

before optical amplification in multi-channel WDM networks, power control, re-

ceiver protection or gain variation in EDFA. The μVOA is designed to withstand

diverse environmental conditions and fully comply with Telcordia GR-1221.

Oplink can provide customized designs to meet specialized feature applications.

Also, Oplink offers full function modules or subsystems by integrating other com-

ponents.
