The characteristics of ultra-long span unrepeated all-optical communication system with G.652 fiber are analyzed.The system structure and primary functions of some composing portions are described.The key factors influencing ultra-long span transmission,which are attenuation,dispersion,nonlinearity,OSNR and so on,are researched.With practical experience,a great many solutions for these restraining elements are proposed,such as using high gain and low noise EDFA,DRA,remote pumped amplifier,dynamic dispersion compensation,fiber nonlinearity restraining and concatenated super FEC.These solutions can provide a good reference for the layout and design of long span unrepeated transmission system.
