Product Details

The Dynamic Variable Optical Attenuator (DVOA) based on microelectromechanical systems (MEMS) is an important component to achieve power regulation in all-optical networks. DVOA can realize comprehensive remote control of all-optical networks. Mainly used in: preset optical power equalization, channel transmission equalization, optical automatic gain adjustment, optical receiver protection, etc. The DVOA products developed by our company use MEMS control chips and unique optical designs, making the products more compact, lower cost, faster in response, higher in stability and reliability, and easy to manufacture.
