| This age,optical fiber networks have entered a period of rapid development,and the popularity has become higher and higher.Users can impose more abundant services on fiber-optic networks,and therefore impose strict requirements on the reliability and stability of access methods.From the current application status,traditional broadband access methods cannot meet the increasing network requirements of people.Changing the access method has become the main way for major operators in China to improve the speed and capacity of the network.Therefore,finding a new type of access technology has become an inevitable development trend and market demand.The emergence of PON(Passive Optical Network Technology)technology can effectively solve this problem.In this technical background,this thesis designs a new access scheme based on PON technology and conducts a comprehensive study on its later application to realize the implementation of FTTX access network and the application of various services.With a view to promoting the widespread use of this technology and promoting the development of China's network technology.This paper uses the combination of theory and practice to complete the application and research of PON technology access network.Firstly,on the basis of reading a large number of related literatures at home and abroad,it expounds the background and research significance of the whole paper design,as well as PON at home and abroad.The current state of application of technology in the access network,followed by the concept,principle,and technical classification of PON technology.Secondly,in order to make readers more comprehensive and in-depth understanding of PON technology,this paper analyzes the key technical points based on PON,including: MPCP(multi-point control protocol technology),ONU automatic identification,multiplexing technology,dynamic bandwidth allocation algorithm.Finally,based on the above theoretical research,this paper develops the scheme design and practical application of the FTTX access network.The design scheme mainly studies the EPON+FTTH scheme and the GPON+FTTH scheme,and then discusses the capacity and performance of the construction project.The practical application effect of the FTTX access network scheme shows that the access network of the PON technology can meet the multi-service usage requirements of users,and the performance index is superior to the traditional access point technology.This article is a refinement of my long-term work project content.Through the design of the whole thesis,I have deepened my understanding of PON technology and various ways of accessing network technology.These precious knowledge reserves and practical work experience will improve me.Ability to work.The end also points out the future NG-PON evolution: a variety of PON hybrid networking,on-demand upgrade,superimposed wavelength,recommended in-depth research and application of PON technology. |
