摘　　要：大容量超长距离(ULH)传输是一种非常有应用前景的技术,文章介绍160×10Gbit/s系统在实际的3040kmG.652光纤上传输的试验情况.系统应用在C+L波段,波道间隔为50GHz,线路发送采用CS RZ码,线路速率10.7Gbit/s,利用拉曼放大器的宽带特性,同时对C+L波段进行色散补偿,使系统成本比分波段进行色散补偿大为降低.试验结果:经3040km传输后,Q值>4.29,光信噪比>15dB,光通道代价<3.5dB,连续24h无误码.The large capacity ultra long haul(ULH) transmission is a very promising technology for future, this paper introduces the 160×10 Gbit/s system transmission experiment over actual 3 040 km G.652 fiber. The system uses C+L band and the channel interval is 50 GHz, adopting CS-RZ as the line code. The line rate is 10.7 Gbit/s. Using the broadband characteristics of the distributed Raman amplification technology, and compensating the disperse in C+L band at one time, we have greatly reduced the system costs as compared to separate band compensation. The experimental results show that after the 3 040 km transmission, Q value is lager than 4.29, the optical path penalty is smaller than 3.5 dB, the OSNR is lager than 15 dB, and the system runs error free for continuous 24 hours.
