Research Of Critical Techniques In FTTH, And Its Applications In Century Garden

This article emphases on discussion of GPON agreement and its application in Century Garden of several critical techniques. Thanks to those critical techniques, GPON can efficiently support multiple of data services and make passive optical network more attracting.Also, as the technical standard for broadband access network, GPON has the most typical character of OAM&P and are able to support a lot of services as well as to provide portability and excellent expansibility for providing more services in the future. Due to access network is closest to final user, so its characters will be inclusive of many agreements and services from current TDM and data services to its new applications in the future like SAN, Digital Visual and so on.By means of GEM adapter and other methods, GPON can be able to provide a distinct transition access by adding PON to those services while in no way interfering the current equipments or altering the transport layer, it will be the most powerful technique to fulfill fiber-optical broad band network.Technology and appl ication of GPON is developing rapidly. It has become one of the hot echnology in the world. Shanxi unicom GPON is also actively involved in the testing and building, I had the privilege to participate in the Shanxi unicom GPON project construction and implementation of the work of the papers from the Shanxi actual projects. The paper first introduces Gigabit-Capable Passive Optical Network (GPON). It summarizes the concept, standards, principle, Protocol, and describes the key technical and advantage at the same time.It introduces the application of technology in Several models, It summarizes the current FTTH technology, analysis of user access network status and needs of different users. According to the company’s needs, we propose Xinzhou mobile GPON network construction strategy and principles, and made its GPON network scenariosWith the price of fiber and GPON equipment cost fal 1 ing and development of technology, the advatanges of GPON’S high performance wi 11 be increasingly obvious. In the future, fiber access become the main means of access. GPON technology wiⅡbe more and more usable.In combination of researches on GOPN agreement and its critical techniques, the application of GPON under the current situation together with assessment on its feasibility will also be given.
