| This paper first introduces the development of PON technology, GPON technology background is briefly described, and the GPON technology before the APON and EPON technology are briefly introduced, at the same time, compare and contrast the two technical description of GPON compared to the advantages of these two techniques, and the architecture of GPON and technical characteristics were described in detail; secondly to existing network operators in the fusion of GPON generated in the process of different fusion methods are introduced, and various methods from a technical and maintenance level has made contrast, highlighted the FTTH in existing fusion of advantage; again on the traditional cable access mode, FTTB+LAN and FTTH are three main ways to do a detailed cost analysis, and according to the country promulgated2008budget standard in Xinjiang Shihezi city5District’s real estate an area carried out a site survey, the district pipeline, line, engine room equipment available and required equipment detail calculation, using "network communication software over the budget" to make a detailed budget, analysis of FTTH in relative to the other two access modes in cost advantages; Finally, FTTH is present from technical, maintenance and cost perspective are very superior fusion methods, it is current and even henceforth a paragraph of time existing operators in the development of GPON network when the first choice. |
