| Abstract: | This paper analyses the key factors in the design of ultra long haul transmission,such as power,dispersion and Optical Signal Noise Ratio(OSNR).It introduced Erbium-doped Optical Fiber(EDFA),dispersion compensation,Forward Error Correction(FEC) and non-linear suppression techniques,and discusses their applications in power system.The basic principle of ultra long haul transmission design is also summed up in the paper. |
