Design And Realization Of GPON Access Network

Communication operators by providing users with a variety of colorfulexperience especially in video business promotion to attract the user’s use, so as toimprove the income level of fixed network. As the user of the bandwidth of thenetwork and the multimedia application requirements gradually improve, copper wirehas been unable to meet the needs of the development of modern communication,along with optical fiber cost falling and the supplementary equipment developmentmature gradually, just in the backbone transmission online application beforeexpensive optical fiber communication equipment were civilian to change gradually,has been more and more applies in the middle of the user access network construction,has achieved the fiber as in the past two years.This paper starts from the development of broadband access technology. Severalmainstream GPON technology, the development and categories of PON technologyare introduced. The functions of every part of GPON network are analyzed. Theadvantages of GPON are presented. Then, GPON structure principle is introduced,and key technology, application mode, network way and device type are detailedstudied. The frame structure of the uplink and downlink of GPON are analyzed.Finally, a FTTH solutions based on the GPON for a residential is proposed. Throughthe FTTH network design, residential GPON FTTH general design, ODN buildingprogram, selection, cost, equipment selection and business bandwidth provision,reflects the feasibility of residential GPON is reflected. GPON is pointed to be thebest program for triple-play and FTTH.Due to the author for a long time in the company of telecommunication networkmaintenance and promotion, many times to participate in HTTB\HTTF plotconstruction and old district fiber reconstruction project, the development process andachievements of modem access networks have a comprehensive understanding of, andthe actual problem such as fiber optic effect have a more thorough understanding.Combined with the various situations encountered in the actual work, the writer in thispaper the basic principle of GPON networks and performance advantages, problemsand development direction of the in-depth analysis of the discussion; Through thenetwork of fiber modification that part has set up complete example elaborates theapplication of GPON technology; Through hands-on application experience for the future promotion and application of GPON access networks put forward its ownviews and opinions.
