4 Tbit/s transmission reach enhancement using 10x400 Gbit/s super-channels and polarization insensitive dual band optical phase conjugation

The data sets collated in the first 12 worksheets comprise the BER measurements of the experiment reported in the associated papers, along with selected optical spectra. Each data point is reported as a mean and a peak to peak range, obtained from 5 individual oscilloscope captures using the signal processing software described in reference 41. Each worksheet shows the same information for a different configuration of the number of superchannels (or conventional channels). Worksheet titles indicate the centre of the band who's measurement results are reported (transmitter optimised for this band) and the number of superchannels used. The first spreadsheet (193T WDM) uses a single sub-channel in place of the 400 Gbit/s super-channels. An additional worksheet reports the Raman OTDR measurement data The worksheets show, to the left of the solid blocked out column - performance without OPC, and to the right - performance with OPC. Presented results are (from top to bottom); A power sweep at the estimated transmission reach used to optimise the launch power, a measurement of the central superchannel as a function of transmission distance, and a measurement of the performance of each superchannel at the maximum reach where all superchannels were found to be operating below the FEC threshold. In addition, typical optical spectra at two transmission reaches are reported. Note, for a given worksheet results with OPC are of course frequency shifted from the without-OPC results.前12个工作表所整理的数据集，包含关联论文所报道实验的误码率（Bit Error Rate, BER）测量结果，以及精选的光学频谱。每个数据点以平均值与峰峰值范围的形式给出，该值由5次独立示波器捕获结果结合参考文献41所述的信号处理软件计算得到。 每张工作表对应一种不同的超信道（或传统信道）配置，展示相同的数据集信息。工作表标题标注了本次测量所针对的波段中心频率（发射机已针对该波段优化）以及所用超信道的数量。首个电子表格（193T波分复用，WDM）采用单个子信道替代400 Gbit/s超信道。另有一张额外工作表记录了拉曼光时域反射仪（Raman OTDR）的测量数据。 在各工作表中，实线分隔列的左侧为未使用光相位共轭器（Optical Phase Conjugator, OPC）时的传输性能，右侧为使用OPC时的传输性能。 本次展示的结果（从上至下依次为）：以预估传输可达距离为场景的功率扫描实验（用于优化发射功率）、以传输距离为变量的中心超信道性能测量，以及在最大传输可达距离下各超信道的性能测量——该最大传输可达距离下所有超信道的工作性能均满足前向纠错（Forward Error Correction, FEC）阈值要求。此外，还提供了两种传输距离下的典型光学频谱数据。 请注意，对于同一工作表而言，采用OPC的测量结果与未采用OPC的测量结果相比，必然存在频率偏移。
