全光通信网技术

介绍了全光网WDM技术的基本概念和其具有的大容量、可升级性好的优越性;阐述了网络节点、管理方案以及网络自愈等方面的技术。全光网络对传统网络的升级主要体现为网络节点从电交换技术到光交换技术的升级,由此引发了网络管理及其相关技术的变化。

Techniques of All-optical Communication Networks

In this paper, the conception and the advantages of the wave divided multiplexing technique used in all-optical networks are introduced, and the techniques of optical cross-connect multiplexing, optical add-drop multiplexing, network managing and auto-healing ring are discussed. In the all-optical networks, the main technique upgraded from traditional networks is optical routing in the network nods. The superiority of large capacity and escalation in all-optical networks is also introduced.
