The Research And Application Of CATV Bilateral Network Based On FTTH Technology

In recent years,owing to the rapid development of global information network,broadband network has become an important infrastructure of the information society.With the further progress and combination of telecommunication network,radio and TV network and the Internet,radio and TV network companies also consider the next step of increasing the bandwidth and network speed.The new generation broadband technology FTTH has features of high bandwidth,uneasiness to be disrupted and stability,and is indeed a best choice for radio and TV network companies to research and develop.CATV bilateral network,based on FTTH technology can maintain the original resources and advantages of broadcasting and television,PON structure can also integrate well with the current cable resources of radio and TV network,providing multiple interactive business for broadcasting and television,broadband connection and video on-demand.Under the background of Village Y's FTTH project construction by Guangxi Radio&TV Network Guigang Branch,the essay analyzes the application of FTTH connection technology on radio and TV network.By researching the features of FTTH communication,networking mode and realization,the author gives a complete bilateral network construction plan for Village Y's FTTH project construction by Guangxi Radio&TV Network Guigang Branch.The major contents are as follow:First of all,it introduces the current conditions and developing tendency of FTTH technology abroad,realizing that FTTH technology has become a mainstream connection technology in China.It indicates the significance of the essay to research the application of FTTH technology on the radio and TV network.Secondly,by researching the communication principle and networking mode of FTTH technology,it should choose an appropriate way of realizing the technology in radio and TV network.The essay applies the FTTH technology based on EPON network structure,double cables and three waves networking mode.According to the reality,it designs a project to launch a headend room,an ODN network and a home network and the whole index of the system by Guigang Branch in Village Y to apply FTTH network.Thirdly,it analyzes and tests the system,including FTTH network testing devices,testing approaches and analysis on the operation performance of the system.
