武汉邮科院牵头承担的国家973项目“超高速超大容量超长距离光传输基础研究”取得T比特级超长距离光传输新纪录,通过采用高谱效率调制、高性能前向纠错编码和特有的非线性补偿技术,完成了单通道1.031 Tbit/s普通标准单模光纤12160公里的传输系统实验。目前,国际上已报道的最高水平是单通道1Tbit/s传输1万公里。
Wuhan National ASTRI’s 973 Project “Basic Research on Ultra-high-speed Very Large-capacity Ultra-long-haul Optical Transmission” Achieved a New Record of T-bit Ultra-long-distance Optical Transmission by Using High Spectral Efficiency Modulation and High Performance Forward Error Correction Encoding and unique non-linear compensation technology, completed a single channel 1.031 Tbit / s ordinary standard single-mode optical fiber transmission line 12160 kilometers experiment. At present, the highest level reported in the world is the transmission of 1 million km of single channel 1Tbit / s.
