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, receiver protection or gain variation in EDFA. The VOA 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 components.
