Epon System Applications, Radio And Television Networks In Mianyang

This article describes the in the States, "triple play" De backdrop, radio and television opportunities facing the network transformation, and cable television departments introduced the development status and HFC cable network's composition and major business, then, discusses Several HFC network for broadband access technologies, including EPON (Ethernet Passive Optical Network, Ethernet passive optical network), EOC (Ethernet over Cable), CABLE MODEM, a brief comparison of the actual combined HFC network Features explained EPON + EoC two-way cable television networks to transform the best choice for reconstruction.Low cost, long life, long transmission distance and high bandwidth, etc.,EPON system is a two-way radio and television cable networks transform one of the best ways, is the realization of "triple play" possible technical means. EPON and EoC discusses multi-service broadband access as a way of excellent features, EoC full use of existing coaxial cable television network, based on EFON + EoC form of two-way cable TV network to be completed by all businesses (eg: three networks unity) and network access capabilities.Paper combined with the actual situation of cable networks in Mianyang, discusses the possibility of improving network to EPON. The backbone of the transport layer from the cable network and user access layer two, two-way cable television network described in detail the specific program of reform and implementation of methods for the practical implementation of the project and provide a theoretical basis. And through cable networks in Mianyang on the actual data records in the client, the network indicator test to verify EPON + EOC application in radio and television cable network operability, and as a basis for realization of "triple play" technical feasibility.In the third chapter.,also introduced a district of Mianyang, radio and television networks in the EPON transformation some of the problems encountered and solutions adopted in which, finally solved the problem.Through technical scheme, and the project implementation process, detailed data to test records of actual cases through the consolidation of the previous conclusions: EPON EOC is started broadcasting the best way of building Ethernet.
