The Design And Implementation Of Broadband Access Network Of Ningxia Telecom Based On EPON Technology

EPON technology can provide 1.2Gbit/s rate of Upstream and downstream,it can provide present and future needs of a variety of broadband services.It has better support for capacity and efficiency for the IP sevice. EPON technology has been widely regarded as the future direction of development of the access network. The main contents of this paper is to study how to use access network technology-based EPON to provide program, and how to optimiz and transform Broadband Access Netword of Ningxia Telecom.This thesis discusses and analyzes the technology of APON, EPON, GPON based on PON technology, then introduces the EPON technology from aspects of system composition, basic indicator, working theory and EPON principle in detail. This paper first briefly introduces the basic principles of technology about PON and EPON, then comprehensively introduces and detailly studys EPON technology involved in agreements and EPON technology used by the key technologies. This thesis analyzes the status and needs of Broadband Access Network of Ningxia Telecom and the problem of Broadband Access Network of Ningxia Telecom and analyzes the feasibile scheme of improvement of Access Network of Ningxia based on EPON technology,and through EPON technical demonstrated the feasibility and necessity of Broadband Access Network of Ningxia Telecom of renovation. Based on various aspects of factor analysis, determined by EPON technology of ningxia telecommunications network optimization and reform are completely feasible. In the paper, the current EPON technology can provide the access network solution in detail, and according to this presents Broadband Access Network of Ningxia Telecom design and implementation plan based on the EPON technology.Then,combines the design concepts and methods of EPON technology,proposes a new optimization program and solution for Boradband Access Network of Ningxia Telecom. According to the implementation, equirements and test methods of EPON technology in the China Telecom's broadband access network,I implement the optimization and transformation of Broadband Access Network of Ningxia Telecom, I also combine IP network optimization and flattening transformation of Ningxia Telecom, analyze and summarize the effect of EPON technology.This thesis mainly passed on the EPON technology research,and combining the existing problems of Broadband Access Network of Ningxia Telecom,and analyse network requirements of the users existing broadband optical access technology, based on the analysis of the application of EPON technology research that EPON technology can adapt to almost all the fixed-line broadband access occasions,and based on its high bandwidth,long distance,less maintenance,provincial resource advantagure and applications in numerous,EPON can provide far more than other access service and quality.Using EPON technology in Broadband Access Networks of Ningxia Telecom, can make the broadband access network of Ningxia Telecom be more reasonable, investment may be more cosd-effective,the uer's access distance to be closer,the user's access bandwidth will be wider.The network can provide a wider variety of business applications for user, and Lay a solid foundation for business expansion and development of Ningxia Telecom.
