保偏PM MEMS光衰减器
PM MEMS VOA
〖简介Introduction〗
基于微机电系统（MEMS）的动态可调光衰减器(Dynamic Variable Optical Attenuator——简称DVOA)是实现全光网中功率调节的重要元件。 DVOA能够实现对全光网的全面远程控制。主要应用在：预置光功率均衡、 信道传输均衡、光自动增益调节、光接收器的保护等。我公司研发的DVOA产品，采用了MEMS控制芯片及特的光学设计，使产品更加小型化，成本更低，并且反应更加迅速，具有更高的稳定性和可靠性，易于制造。
Dynamic Variable Optical Attenuator (DVOA) based on MEMS is an important component for power regulation in all-optical networks. DVOA can realize the full remote control of all optical network. The main applications are: preset optical power balancing, channel transmission balancing, optical automatic gain regulation, 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.
