Research Of Broadband Access Technology Based On GPON

GPON technology is the ITU-T according to the operator to carry out the businessneeds of a new generation of broadband access standard, which has a high transmissionefficiency, and high-speed wide-score light ratio as well as for long-distance transmissioncharacteristics for the operators to carry out a comprehensive digital business networkingcostsavings, and guarantee the QoS of business. The GPON standard also provides for theoperation and maintenance of the access layer management functions as well as theprotection mechanism, saving costs for maintenance and fault handling operators at theaccess level.The GPON achieve FTTX popular technology, is the ideal technology toachieve high-bandwidth access network.In this paper, a method of combining theory and practice of GPON technology basedbroadband access study, an overview of the thesis theoretically docking network concept,characteristics, access technology, and fiber access network defined its network structure,and by a comparative analysis of the history of the development of the PON network theory,EPON technology, GPON technology analysis. Then by the theory of comparative analysisand practice combined analysis theory and network construction advantages of GPONtechnology. Followed by case analysis method selected Shenyang Railcom case to caseanalysis based on the the GPON technology of broadband access solutions, the necessity ofShenyang Railcom GPON broadband access solutions, feasibility, construction programanalysis and economic evaluation of the access comprehensive evaluation program, througha comprehensive analysis and assessment, Shenyang Railcom broadband access solutionbased on GPON technology feasibility. GPON technology for broadband access case on thebasis of the analysis by the theory and Shenyang Railcom access program, select A district ofShenyang, A residential user bandwidth demand analysis, and optical line terminal, opticalnetwork unit, splitter, power supply planning to determine the selection of fiber optic cable,and program implementation process should pay attention to the problem description, finalacceptance testing network.20A district unit of user access, for example, based on the theGPON technology of broadband access methods and traditional ADSL access, nocomparative analysis GPON technology based broadband access has can match advantage and satisfied.
