Telecom City Of Optical Network Construction Research And Design

At present,China’s broadband network continues to develop,the number of broadband users and Internet traffic continues to increase.Traditional ADSL and LAN access methods can not meet the current business development because of technical limitations.At present,Jiangxi Telecom,some of the major businesses such as high-definition ITV,green IP network,video surveillance,network bandwidth and network security are demanding.Therefore,the need for core network and access network upgrade rectification in order to meet business development needs.Based on the network development plan of Jiangxi Telecom in 2016,this paper puts forward the requirements of optical network construction,the main work is as follows:(1)Analysis of the existing problems and shortcomings of the existing network,according to the development needs of Jiangxi Telecom broadband business,the metro upgrade and rectification needs.(2)A detailed analysis of the relevant knowledge and technology,including core network technology,access network related to the main knowledge and key technologies related to the terminology of this article to explain the terminology.(3)According to the development of Jiangxi Telecom’s broadband,the upgrading scheme of the original optical core network in the urban construction of optical network is given,which includes architecture design,VLAN planning,equipment selection and network management system design.(4)According to different user access environment,a detailed technical analysis was carried out,and the original optical copper hybrid access network was upgraded to all-optical access network,including: optical access network design,network Translation scheme analysis,differentiated user translation scheme,equipment selection and so on.Finally,it points out the characteristics of this paper and the direction of further efforts.
