Mini MEMS VOA (Reflection-type)
Dynamic Variable Optical Attenuator (DVOA) based on MEMS is an important component to realize power regulation in all-optical network. DVOA can realize the comprehensive remote control of all-optical network. Mainly used in: preset optical power equalization, channel transmission equalization, optical automatic gain adjustment, 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.
