MEMS Voltage Type Variable Optical Attenuator Products
Introduction: 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.
