產(chǎn)品詳情
〖簡介Introduction〗
基于微機電系統(tǒng)（MEMS）的動態(tài)可調(diào)光衰減器(Dynamic Variable Optical Attenuator——簡稱DVOA)是實現(xiàn)全光網(wǎng)中功率調(diào)節(jié)的重要元件。 DVOA能夠?qū)崿F(xiàn)對全光網(wǎng)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(diào)節(jié)、光接收器的保護等。我公司研發(fā)的DVOA產(chǎn)品，采用了MEMS控制芯片及獨特的光學設計，使產(chǎn)品更加小型化，成本更低，并且反應更加迅速，具有更高的穩(wěn)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. It can realize the full remote control of all optical network. Here are some main applications: 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.
