Research On Integrated Access Technology For Cable TV Network

This paper introduces how to apply EPON and EOC technology to the access of Heilongjiang CATV network,and how to realize the two-way access of traditional HFC network with more advanced technology,so as to enable the CATV network to realize two main types of business,mainly TV broadcasting and cable network,and to provide strong market competitiveness for the realization of intelligent network interconnection business of Heilongjiang CATV networkStarting with the development of CATV network access technology in China,this paper first gives a detailed understanding of the development history of CATV network and its access technology,introduces the development status of CATV network access technology at home and abroad,and then expounds the purpose and significance of this topic,and deploys the structure of the article.Then it focuses on the related technologies of single CATV access network,such as HFC,EPON and EOC,which are commonly used at home and abroad,as well as the current situation and problems of each technology.It also gives a detailed introduction and analysis of the advantages and disadvantages of these technologies,which provides a choice for the research direction of the subject.Secondly,aiming at the defect of single access technology,this paper introduces some combined access technologies of CATV access network,which are used to solve the defect problem at present.At the same time,the related technologies are analyzed in detail from which the development direction and the existing problems of combined access technology are extracted,and the research direction of this topic is pointed out.Aiming at the problems existing in the previous single and combined access technologies,this paper proposes an innovative combination access technology based on EPON,EOC and ASON.The practicability of this combination technology is studied.Taking the access of Heilongjiang CATV network as an example,the planning of Heilongjiang CATV integrated information network is introduced in detail.The overall structure of Heilongjiang CATV network urban network is mainly introduced,and the network structure planning is put forward.Each level of the network has a detailed plan.Finally,the network performance is analyzed and tested.The transmission index analysis and overall performance analysis after the design of Heilongjiang Radio and TV Network are introduced.The new services that can be carried out are introduced,and the network performance is tested.At the same time,the work of this paper is summarized and the future work is prospected.The research work of this paper has practical value for promoting the development of CATV network access technology in our country,promoting the construction of smart city in our country,and promoting the development of triple play in our country.
