Dynamic Variable Optical Attenuator (DVOA) is the important device for realizing full optical network power in the regulation and it based on the micro electrical mechanical system. DVOA can realize the long-distance control of optical network. The main applications of DVOA are: Light path power balance, channel transmission equilibrium, light automatic gain regulation, optic receiver protection etc. Our company's DVOA products use MEMS chips and unique optical design which make products smaller and the cost lower. Meanwhile, our products have fast reaction speed, high reliability and stability.
