摘要

SDH网络具有刚性管道的优点，在高等级业务承载时不可替代，但由于设备老化等问题，面临退网。针对SDH网络面临的现状，提出了一种融合VC交叉功能的OTN技术方案，在利用OTN系统大带宽的同时，节约了机房空间、能耗及纤芯资源，降低了运维风险，为SDH替换改造提出了新的思路。经试点及测试后，系统工作正常，指标满足技术规范要求。

Abstract

Due to the advantage of rigidity pipeline

SDH is irreplaceable in carrying high priority service circuit.However

it will withdraw because of equipment ageing.A solution of OTN system with VC cross-connecting function was proposed for the situation which SDH network faced

which could minimize space requirements

conserve energy

save the resource of optical fiber and reduce the operational risk while keeping the advantage of OTN high bandwidth transmission.Pilot testing proves that the system works well and accords with correlative criterion.
