MEMS Voltage Type Variable Optical Attenuator Products

 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.
