Residential Broadband Access Network Based On Gpon Technology Research And Application

As carriers of staff, can deeply feel since entering the 21st century, the rapid development of broadband services worldwide, with the rapid development of broadband services, broadband access networks will inevitably continue to put forward new demands. Ways to tackle the use of broadband access network for the new telecom operators demand has become one of the more urgent. From the current broadband access network technology in the international and domestic development situation, both in optical fiber technology cost price, service life, maintenance costs, or in support of all aspects of broadband service has shown a clear advantage, but from the current a variety of fiber access technology comparison, Gigabit passive optical access network technology (ie: GPON) and even more of a chip, Its superiority is mainly reflected in: 1) It is based on the latest generation of ITU.TG984.X standard broadband passive optical network access technology; 2) to achieve longer distances; 3) to achieve higher bandwidth; 4) has the spectral characteristics; 5) GPON supports Triple-play services, competition can provide full-service solution that can effectively solve the twisted-pair access bandwidth bottlenecks, high-bandwidth services to meet users'needs; 6) part of the world's largest operator from providers are selected GPON technology, GPON believe that as the representative of broadband access network will be more and more widely used.The paper-based GPON residential broadband access technology research and application for the study, in-depth analysis of GPON architecture, related protocols, works in the access network applications, and its key technology based on the realization based on GPON residential broadband access Leshan CRC research program, and finally to Leshan Lai Fushi residential broadband access specific applications, for example, introduced GPON technology based residential broadband access throughout the process. The main contents are:1.In-depth analysis of the GPON system architecture, related protocols, works in the access network applications, and analysis of its key technology research, has found that, GPON technology applications in broadband access network has obvious advantages, the application prospects are very broad, and has become China's current broadband access network in the mainstream.2.Adoption with XDSL GPON , APON/BPON EPON , such several mainstream broadband access technologies in contrast the performance and cost of the investment in stark contrast to the description of the technology-based small area GPON broadband access, whether in terms of facility investment, users of FTTX enjoyed a broadband speed connection, or fiber-optic access costs, as well as an integrated operational support has a significant performance advantages and cost advantages through; moreover, the Leshan CRC GPON technology to achieve small district-based broadband access to the necessity, feasibility, economic evaluation, building programs, as well as access to users, and planning for a case-by-one study from a different perspective on Leshan rail links based on GPON technology to achieve small district broadband access program, and the feasibility to Leshan lavery taxi small district of broadband access as an example, the small area of technology based on GPON broadband access to the detailed analysis of specific applications.3.Last to laifushi community 1 building 1 unit of access for cases, focus on used GPON programme and currently using of ADSL programme in price/performance aspects of different for has comparison, focus in business outputs, and Council end device inputs, and room device inputs, and cable resources inputs, and games dimension cost aspects for has comparison, from comparison of data can see used GPON programme more traditional programme in price/performance aspects has obvious of advantage.
