work Design (Cable Part) Of munication
And Transmission System From Xi’an to ShangZhou
 
Abstract: This essay introduces work design of munication and transmission system from Xi’an to ShangZhou. This essay studies optical transmission system, railway munication system and the structure of the work which starts out munication requirement of the railway. According to the requirements of the task book, this paper proposes the project program of the capacity of munication systems, communication lines, network infrastructure, protection mode from Xi’an to ShangZhou. At the same time, the configuration of SDH equipment in each site are also introduced in the munication and transmission system from Xi’an to Shangzhou. What’s more,the distance of light relay has been calculated. According to position principle of the work, the SDH (1 +1) backbone transmission system is made of four-core optical fiber from Xi’an to Shangzhou. We connect the transmission equipment of SDH 622M in Xi’an, XinFengZhen, BaYuan and ShangZhou stations by two-core optical fiber to make up the local work . work system posed by the two-core optical fiber access to OLT and multiple ONU. At the same time, protective measures of work layer has also been considered. As a result, work design is clear and safe.
