摘要
在IP业务的高速增长和WDM技术提供超大容量带宽资源的双重刺激下 ,传统光网络正在朝着适于传输IP业务的新一代光网络演进。本文描述了WDM光传送网的发展与现状 ,讨论了基于OXC和OADM的WDM光传送网技术 ,并对下一代光网络的发展进行了分析和展望。
Due to the rapid development of IP applications and the requirement of high_capability of the transport network, the traditional optical network is moving forward IP_based optical network based on WDM technology. This paper reviews the present status and development of WDM optical transport network , discusses the techniques of the WDM all optical network based on OXC and OADM, Finally, the evolution for the next generation optical network is presented.
