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,文章介绍了32×10Gbit/s系统在实际的3040kmG.652光纤上传输的试验情况.线路发送采用NRZ码,具有符合G.709的OTU2格式的线路速率,系统应用分布拉曼放大技术.试验结果表明,经3040km传输后,Q值>3.82,光通道代价<1.6dB,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 32×10 Gbit/s system transmission experiment in an actual 3 040 km G.652 fiber line. The system, adopting NRZ as the line code and employing the distributed Raman amplification technology, has a bit rate of OTU2 format in accordance with G.709. The experimental results show that after the 3 040 km transmission, Q value is lager than 3.82, the optical path penalty is smaller than 1.6 dB, and the system runs error free for continuous 24 h.
