The dynamic variable optical attenuator (DVOA) based on microelectromechanical system (MEMS) is an important component for realizing power regulation in all-optical network. DVOA can realize comprehensive remote control of all-optical network. Mainly used in: preset optical power balance, channel transmission balance, optical automatic gain adjustment, protection of optical receiver, etc. The DVOA product developed by our company adopts MEMS control chip and unique optical design, making the product more miniaturized, lower cost, more responsive, more stable and reliable, and easy to manufacture.
