传输网络第三条路由的设备解决方案

Solution of equipments of the third routing in transmission network

本文介绍了传输网络在某一节点建设第三条光缆路由时的设备解决方案。同时对OLP技术、OLP各种实现方式及工程中应注意的事项进行论述。对于利用交叉单元实现第三路由的接入,本文着重阐述了SDH网络及OTN网络光、电层面交叉技术的实现方式和局限,并最终提出两种技术的应用思路。

The solution of equipments using in contributing the third optical cable routing on a certain node in transmission network was introduced in this paper.Technology,realization modes and precautions of OLP were discussed as well.Realization modes and limitations of electro-optical cross level technology in SDH network and OTN network were emphatically described about accessing the third routing using cross-unit,and application thought of these two technologies were put forwards.
