超宽带传输利用标准C频段以外的带宽实现显著的网络容量升级。将标准C频段升级到C+L频段传输方案已经可行，并且正在S、E和O频段进行探索性传输，以调查这些频谱区域中的传输质量(QOT)损害。在这篇文章中，利用混合放大器和掺铋光纤放大器(BDFA)对SCL波段和部分E波段进行了实验传输，其中SCL波段采用离散拉曼放大，E波段采用掺铋光纤放大器。通过这个传输带宽，我们证明了在70公里的标准单模光纤上，以150个相干信道传输36Tbit/S是可能的。这一结果与宽带物理层模型进行了比较，该模型考虑了现实的全频谱负载传输场景，其中E频段被74个信道占用，总共提供221个信道。这一比较表明，对于本实验中的两种情况，最大的损伤出现在S频段，而将E频段添加到SCL频段对C和L频段内的QOT的影响可以忽略不计。
Ultra-wideband transmission utilizesbandwidths beyond the standard C-band to enable significant network capacity upgrades. Upgrading the standard C-band to a C+L-band transmission scenario is already feasible, and exploratory transmission is being performed in the S-, E-, and O-bands to investigate quality of transmission (QoT) impairments in these spectral regions. In this article, experimental transmission through a SCL- and partial E-band spectral region is performed, with use of a hybrid amplifier that exploits discrete Raman amplification for the SCL-bands, and a bismuth-doped fiber amplifier (BDFA) for the E-band. Through this transmission bandwidth, we demonstrate that 36 Tbit/s transmission is possible, with 150 coherent channels over 70 km of standard, single-mode fiber. This result is compared to a wideband physical layer model that considers a realistic full spectral load transmission scenario, where the E-band is occupied by 74 channels, providing a total of 221 channels. This comparison demonstrates that, for both scenarios in this experiment, the greatest impairment is present within the S-band, and the addition of the E-band to a SCL-band scenario has a negligible impact upon the QoT within the C- and L-bands.
