本文在德国电信96.5公里现网G.652光纤上，利用130 GBaud DP-PCS高阶QAM与仅EDFA放大，实现56.51 Tb/s DWDM及1.71 Tb/s单通道传输，并创下1.88 Tb/s B2B净比特率。
摘要：
我们报告了一项行业领先的光密集波分复用（DWDM）现场试验：在高容量数据中心互连（DCI）场景中，采用130 GBaud双偏振概率星座整形256进制正交幅度调制（DP-PCS256QAM），使每通道线路速率超过1.66 Tb/s。该研究试验在德国德国电信96.5公里现场部署的G.652标准单模光纤基础设施上进行，仅采用掺铒光纤放大器（EDFA）进行放大。系统以150 GHz间隔共传输34个通道，总光纤容量为56.51 Tb/s，频谱效率高于11 bit/s/Hz。在单通道传输场景中，同一链路上实现了1.71 Tb/s。此外，我们使用130 GBaud DP-PCS400QAM，在背靠背（B2B）条件下成功演示了1.88 Tb/s的创纪录净比特率。
英文摘要：
We report an industry leading optical dense wavelength division multiplexing (DWDM) field trial with line rates per channel exceeding 1.66 Tb/s using 130 GBaud dual-polarization probabilistic constellation shaping 256-ary quadrature amplitude modulation (DP-PCS256QAM) in a high capacity data center interconnect (DCI) scenario. This research trial was performed on 96.5 km of field-deployed standard single mode G.652 fiber infrastructure of Deutsche Telekom in Germany employing Erbium-doped fiber amplifier (EDFA)-only amplification. A total of 34 channels were transmitted with 150 GHz spacing for a total fiber capacity of 56.51 Tb/s and a spectral efficiency higher than 11bit/s/Hz. In the single-channel transmission scenario 1.71 Tb/s was achieved over the same link. In addition, we successfully demonstrate record net bitrates of 1.88 Tb/s in back-to-back (B2B) using 130 GBaud DP-PCS400QAM.
