摘要
首先介绍对未来光接入网的考虑。于是依次说明未来地区接入网的结构 ,接入结点利用波分多路技术后的连接功能 ,以及光纤双环网的保护作用。
The paper begins with introducing the considerations on proposed new type of optical access network for data centric communications.Then,it describes the architecture of such optical regional access network,the functionality of wavelength division multiplexing based access nodes,and the optical protection scheme of dual fiber ring.Finally,it enumerates the component elements required in WDM based optical access network.
