PM MEMS VOA
〖簡介Introduction〗
基于微機電系統（MEMS）的動態可調光衰減器(Dynamic Variable Optical Attenuator——簡稱DVOA)是實現全光網中功率調節的重要元件。 DVOA能夠實現對全光網的全面遠程控制。主要應用在：預置光功率均衡、 信道傳輸均衡、光自動增益調節、光接收器的保護等。我公司研發的DVOA產品，采用了MEMS控制芯片及特的光學設計，使產品更加小型化，成本更低，并且反應更加迅速，具有更高的穩定性和可靠性，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.
