基于DWDM全光网关键技术的探究

Research on the Key Techologies Based on DWDM All-optical Networks

基于DWDM的全光网技术为互联网的发展、研究拓宽了视野。介绍了全光网的发展、DWDM全光网的特征、全光网的基本结构、光交叉连接和光分插复用 (OADM )关键节点技术 ,讨论了光网互联器件的机理。

With the view for advance and research of Internet based on optical networking of IP over DWDM,the paper first describes the development,characters,basic architecture and pivotal node and optical transfer parts of all-optical networks.Then,it also discusses the optical Internet networking based on IP over DWDM technologies and self-recover of IP over DWDM and so on.
