Design And Implementation Of Jiangxi Unicom The Secondary Mainline Transmission Network

With China Unicom and China Netcom restructured into China unicom, the secondary mainline transmission network of Jiangxi unicom composition by the Secondary mainline transmission network of the original unicom and original Netcom. The secondary mainline transmission network of Jiangxi unicom load cities's long-distance circuit such as fixed telephone and mobile communication, data communication, IP, important customers line of business, transmission resources of Jiangxi Unicom more abundant after fusion, can make full use of mutual resources expansion and optimize the existing the secondary mainline transmission network.Meeting needs of various business development, and further improve security and robustness about the secondary mainline transmission network of Jiangxi Unicom, promotes competitiveness about Jiangxi Unicom in jiangxi's communications industry.The thesis mainly introduced related transmission technologies, including the basic theory of optical fiber communication, light emitter and optical receiver, optical fiber communication technology, transmission network technology, WDM optical transmission network. Mainly introduces SDH technology principle and SDH network, several self-healing ring network structure and characteristics of transmission network technology in detail, etc. Introduce the present situation of Jiangxi Unicom transmission network. Detailed analysis characteristics and needs of the secondary mainline transmission network of Jiangxi Unicom, formulate construction plan about the secondary mainline transmission network of Jiangxi unicom. Finally introduces implementation process about the secondary mainline transmission network of Jiangxi unicom in detail.The construction schemes that the paper involves are based on needs, which of meeting the expanding business and improving the level of security about the secondary mainline transmission network of Jiangxi Unicom, can implement in the short term, the secondary mainline transmission network were implemented that can satisfy needs of the business development, The business of bearing can be to protect more effective. I participated in the project planning and design, project implementation and other links, I am responsible for design and implementation about the secondary mainline transmission network, Completed the setting objectives.Related technology research of the paper enabled us recognite the importance about the route transmission network in throughout the communication network. Transmission is based network in communications network, various business are carrying on the transmission network. Constructe the transmission network of meeting the expanding business needs and providing safe and reliable, which is imperative.
