At present,the main communication modes in China include wireless communication,wired communication,microwave communication and optical fiber communication.Among them,optical fiber communication has become the main application medium because of its stable transmission quality,high transmission speed,strong anti-interference ability and low cost.It occupies an important position in the whole communication industry in China.Therefore,communication operators and equipment manufacturers have invested a lot of manpower and material resources to develop optical fiber communication technology,among which the communication technology represented by ultra long span optical fiber communication technology Information technology has reached the world's leading level.The essence of optical fiber transmission system is a closed-loop transmission system.The optical fiber transmission system has the characteristics of multiple lines interleaving,so it is inevitable that there will be signal interference in the transmission process.The ultra long distance transmission is more sensitive to the signal transmission quality interference,because the longer the optical fiber transmission line is,the lower the transmission rate.Therefore,in order to effectively improve the network speed and utilization rate,it is necessary to scientifically study the configuration technology of optical fiber amplification equipment in the actual application of ultra long span optical fiber communication according to the actual needs of ultra long span optical fiber communication,form a theoretical scheme,establish a theoretical model of optical fiber amplification equipment,and carry out test simulation tests,and draw scientific conclusions.It is not only of great theoretical significance,but also of great practical value in practical production and application to explore the relationship between the parameter configuration of Raman amplifier,erbium-doped fiber amplifier(EDFA),remote pump amplifier,hybrid amplifier and the transmission quality,speed and other performance of ultra long span fiber communication.The research content of this paper is the ultra long span optical fiber communication technology in a province.Combined with the current situation and practice of the relevant communication transmission system,the ultra long single span transmission system and the ultra long span non relay transmission system are mainly studied.Firstly,the paper analyzes the background and significance of the subject,discusses the optical fiber communication technology and communication module,and summarizes the realization method of the ultra long span optical transmission.The influencing factors of ultra long span communication and the key technologies of ultra long span optical fiber communication are discussed,which form the theoretical and technical support for the follow-up application research.Finally,the application scheme of a province's super long span is analyzed.Based on the infrastructure of pre amplifier + power amplifier + signal wavelength converter,combined modules are added according to the actual needs,which is easy to form a construction scheme,and easy to remove obstacles and maintain in the later stage.The 4-band 10 g / 2.5G hybrid transmission technology planning mode is adopted,which has strong application operability and excellent performance indexes,and conforms to the industry and technology in the future The application effect is good.Through the application analysis of transmission node,optical power loss and link signal-to-noise ratio,the application performance test is carried out to form the final research conclusion.
