Design And Implementation Of Tianjin Broadcast And TV Network Based On EPON

After continuous development, Cable television network has not only become oneof the important information infrastructures in China, but also has the huge bandwidthresources and extensive application prospect. The one-way CATV network reformtraditional becomes a comprehensive information service network two-wayinteraction is an inevitable trend. With the development of EPON technologycontinues to mature, EPON has got more and more applications in telecom networkinfrastructure construction. This paper studies the design and implementation ofTianjin broadcast and TV network based on EPON.Fist, the paper introduces the structure of EPON network and briefly describes thecomposition and working principle、the key technology of EPON system、serviceconvergence、technology advantages. Because the user access network construction ofthe original network exists and high maintenance cost、 management is notconvenient、providing business less species、low bandwidth, it proposes two solutionsbased on EPON technology, through the EPON analysis in the application model ofTianjin broadcast and TV network.The paper mainly introduces and studies two kinds of access technology based onEPON, describes in detail program content、system design、system implementationand the debugging process scheme, summarizes the construction experience of EPONaccess network.Through the application of EPON in Tianjin broadcasting model analysis, the paperproposes EPON+LAN and EPON+EOC access program. The characteristics of thesetwo programs is low cost, easy to implement and easy to manage. For EPON+LANand EPON+EOC two access methods for system design, and give specific alterationprograms. Through comparative analysis of the two access methods, obtainedEPON+LAN solution is more suitable for new residential service access，EPON+EOC program is suitable for the transformation of the old district serviceaccess.
