全光网络关键技术及其安全管理

Key Technologies of All-optical Network and Its Safety Management

重点分析波分复用的优点和现有网络同步数字系列的不足.综述全光网络的关键技术即光交叉连接和光分插复用,并说明它们是克服现有网络节点瓶颈问题的有效解决方法,同时就其新增加的物理光层而新面临的安全管理问题进行了详细探讨.

This paper puts an emphasis on the advantages of the wave division multiplexing(WDM) and the drawbacks of the available synchronous digital hierarchy(SDH),and analyses the key technologies of the AON, such as OXC and OADM, which can be used to effectively overcome the bottle-neck effect of the network. In addition, the safety management of the AON that has a new additional physical optic-layer is dealt with in more detail.
