Design And Implementation Of Access Network Based On GPON Technology

The Internet has now become the main medium for people to communicate with the world and obtain information.With the rapid development of the Internet,various new types of business continue to emerge.People's demand for the Internet is also increasing.It requires not only network bandwidth,but also new network services.Traditional network access is mostly based on XDSL.This access mode uses copper cable as transmission medium,with low transmission rate and poor support for new network services.Therefore,it has been unable to meet users' online needs.Network operators must provide new technical solutions to meet customer requirements while ensuring revenue.Based on the actual network status of Urumqi Tietong Company,this paper proposes a design scheme of access network based on GPON technology,which can effectively solve the current dilemma of Tietong Company.At the same time,video monitoring and access scheme is designed based on GPON access technology.This scheme achieves the collection of high-definition video information at a low cost,providing effective guarantee for the stable development of xinjiang.Firstly,the paper introduces the background and significance of the research.It analyses the predicament of current user network access.On this basis,it studies the key technologies of different access networks.It also compares and analyses the advantages and disadvantages of XDSL and PON technology.It focuses on the analysis of access network technology based on GPON.It analyses the structure,technical characteristics,networking mode and related key technologies of GPON system.Secondly,it analyses the overall scheme design of access network based on GPON technology.Based on the analysis of the current access network status of Wushi Tietong Company,the related factors restricting its development and the basic requirements of access network technology updating are clarified.It focuses on the analysis of the requirements of GPON technology and its planning principles,and clarifies the key technical indicators of GPON technology and the basic principles of GPON network planning.It discusses the overall scheme design of access network based on GPON technology and the specific scheme design of each module.It discusses the setting and deployment strategy of OLT unit,ODN unit and ONU/ONT unit in detail.This paper analyzes the design of real-time camera monitoring scheme based on GPON access,compares and analyzes the advantages and disadvantages of the video streaming scheme and the facial image capturing scheme,and finally selects the real-time camera monitoring scheme based on GPON access based on the characteristics of GPON access technology.Based on the actual project of Wushi Tietong Company,this paper analyses the implementation of GPON access network scheme in detail.Based on the analysis of users' network service requirements,it designs a networking scheme based on GPON access.It plans the data broadband according to the user's needs and calculates the loss of ODN link.It analyses the selection and configuration of OLT equipment,the configuration of optical splitter,the construction of backbone optical cable and the planning of GPON network priority.The implementation of video monitoring based on GPON and the deployment of portrait recognition system are studied.Finally,the actual implementation effect is tested and verified.The actual test shows that after GPON optical fiber access,the network bandwidth can reach 10 Mbps,which can support the new service functions required by users,and the actual operation effect is good.The test of video monitoring based on GPON is completed.The successful implementation of the scheme effectively improves the network environment in xinjiang and provides a network platform for the stable construction of xinjiang.It will be a design reference for other similar projects,with a high template demonstration role.
