IntroductionDynamic Variable Optical Attenuator (DVOA) based on
MEMS is an important component for power regulation in all-optical
networks. DVOA can realize the full remote control of all optical
network. The main applications are: preset optical power balancing,
channel transmission balancing, optical automatic gain regulation,
optical receiver protection, etc. The DVOA product developed by our
company adopts MEMS control chip and unique optical design, which
makes the product more miniaturized, lower cost, and more rapid
response, with higher stability and reliability, and easy to
manufacture. FeaturesApplicationsHigh reliabilityHigh
