On Application Of Fttx-Telecommunications Access Network Technology

In recent years, as represented by the Internet revolution is profoundly changing the traditional concept of telecommunications and architecture, with the progressive opening of national access network market, telecom regulatory policy relaxation, growing competition and expansion, the rapid emergence of new business requirements, wired technologies (including fiber optic technology) and the development of wireless technology, access networks started to become the focus of attention.Traditional telecom access network consisting primarily of the twisted pair copper cable, regardless of the advanced technology, available bandwidth and distance of the copper is somewhat limited, unable to meet the needs of a large number of video information transfer, in particular real time video transmission, need sufficient access to network bandwidth, the last mile into all business requirements of "bottlenecks".Driven by the huge market potential, producing a variety of access network technology.Optical access technology matured in recent years, rapidly falling cost, in order to build a new optical access network provided a good basis.This papers describes has telecommunications access network concept, and classification and technology development course at first, followed detailed addressed current main of advanced access technology--FTTH, third, research the technology in practice in the of application, design different of group network programme, in new buildings, and transformation community, various different scene achieved, analysis different group network programme corresponds to specific scene cost, area of pros and cons, Ⅳ, detailed described fibre access technology in Yancheng XICHENGYIPIN community products FTTH cover construction project process in the of specific achieved, Finally on the access network technologies, looking in the direction of development.
