Research Of Network Application Based On GPON

GPON technology, one of the top technologies to achieve FTTX, is based onITU-TG.984.x standard, a new broadband passive optical standard. Relative to the current technology of access to Network, GPON technology features high bandwidth and effcient transferring, splitting ratio and long transferring distance. GPON greatly saves operators'optical fiber resource and offers Qos assurance to various types of operation and it also provides the protection mechanism on the access to network,complete OAM function and fiber auto-switching time which should be less-than 50ms。GPON supplies a unified access platform and saves the operators'cost to maintain and process damage. The basic structure of network based on GPON technology is similar to current PON, which is made up of local OLTO and users' ONU, the single-model fiber linking the former two equipments, ODN made up of pos.passive optical splitter and network management system.GPON is the ideal technology to realize broadband and comprehensive improvement.This treatise keeps a foothold on the enterprises'internal requirements for sustainable development, analyzes the case that GPON takes the place of XDSL in the broadband network construction to investigate the application of GPON as new broadband access technology.This treatise focuses on three points, which are the discrepancy of XDSL on technology evolution,performance and capital cost in the sustainable development of corporations; comparative analysis on new principal standards of broadband access,such as APON/BPON, EPON,GPON etc and cost supremacy of GPON; and research of practical application of GPON in Yuxi Branch of China Tietong Corporation.This treatise combines theories with practical work, focuses on full integration of theoretical research and engineering practice. And through researching the practical application of GPON technology, a new generation of broadband access network technology and accumulating practical experience, this treatise tries to find a way for corporations'sustainable development by cutting cost and improving quality to gain market share.
