全光通信及其关键技术的分析与探讨

Analysis of Full Optic Fiber Communications and its Core Technology

介绍全光通信网的概念 ,从光通路层网络、光复用段层网络、光传输段层网络 3个垂直方向的独立网络层对光网络结构进行分析 ,说明物理媒质层对整个光网络的支持作用 ;同时 ,从全光交换网络技术、光交叉连接、全光中继、光复用技术等方面探讨全光通信的几种关键技术 ,论述全光通信的优越性及其发展前景。

An introduction is given to the concept of full opt ic fiber communications. An analysis was made of the optic network structure fro m optic channel layer, optic repeat layer, and optic transmission layer\|the thr ee independent vertical network layers, indicating the backing role of physical medium layer to the entire optic network. Discussions were made of key technolog ies of full optic fiber communications from full optic switching network, optic cross connection, full optic relay, and optic repeat, presenting the advantages and prospects of full optic fiber communications.
