西安铁路枢纽通信骨干传输网的建设研究

根据西安铁路枢纽通信网络存在的问题分析,结合通信传输技术的发展,确立采用OTN技术搭建枢纽骨干传输网。通过分析枢纽内的传输系统容量,确定了骨干网的系统规模。结合枢纽现状确定骨干节点设置,根据传输业务内容确定保护方式、波道分配。调查既有光缆资源,明确统光纤运用,构建起西安枢纽的骨干传输网,改善了枢纽内的传输条件,提高了通信网运行的可靠性。

Research on Backbone Communication Transmission Network Construction of Xi'an Railway Hub

According to the problems existing in the Xi'an Railway Hub of communication network analysis and based on the development of the communication transmission technology,it is determined to use OTN technology to establish the hub backbone transmission network. Through the analysis of the transmission system capacity within the hub,the size of the backbone system is defined. In combination with the node setting of the hub status and according to the transmission business content,the protection method and the channel allocation are finalized. The survey of the cable resources and the identification of optical fiber system application serve to build up the hub of Xi'an backbone transmission network,and improve the transmission within the hub and the reliability of communication network operation.
