通过利用标准单模光纤（SSMF）的低损耗光学窗口的未使用的光谱带来增强容量是满足未来数据流量需求的具有成本效益的解决方案。可以在不同光谱波段工作的光放大器的发展有望在多波段网络的建立中发挥不可或缺的作用。在这项工作中，我们进行实验，分析和数值模拟的多波段传输系统使用的混合分布式离散拉曼放大器，使信号放大从1410-1605 nm。所开发的放大器使用200 Gbit/s通道在50 km的SSMF上进行了测试，成功实现了传输，远高于8.5 dB的HD-FEC阈值。进一步研究了多频带传输性能，使用半解析的封闭形式近似和基于分步傅立叶方法的模拟各种相关的测试用例。分析和数值模型也与实验结果进行了比较，显示合理的协议，在系统性能估计。
Capacity enhancement by utilising the unused spectral bands of the low-loss optical window of standard single-mode fibre (SSMF) is a cost-effective solution for meeting the future demand of data traffic. The development of optical amplifiers that can operate in different spectral bands is expected to play an integral part in the establishment of multi-band networks. In this work, we perform experimental, analytical and numerical modelling of a multi-band transmission system using a hybrid distributed-discrete Raman amplifier enabling signal amplification from 1410–1605 nm. The developed amplifier was tested over 50 km of SSMF using 200 Gbit/s channels, where successful transmission was achieved, well above the HD-FEC threshold of 8.5 dB. Further study on the multi-band transmission performance was carried out using a semi-analytical closed-form approximation and split-step Fourier method-based simulations for various related test cases. The analytical and numerical models are also compared with experimental results, showing reasonable agreement in terms of system performance estimation.
