Abstract
We propose an innovative optimization framework using a multi-objective genetic algorithm to simultaneously optimize the launch power profile and design Raman amplifiers. Its flexibility allows us to find better solutions and reduce the number of Raman pumps. Moreover, we utilize the framework to compare the potential of four multi-band transmission systems leveraging hybrid fiber amplification. Simulation results highlight that complementing a C + L-band system with the S-band leads to higher total system capacity than using the E-band or interleaving data channels and Raman pumps.
我们提出了一种创新的优化框架，利用多目标遗传算法同时优化发射功率曲线和设计拉曼放大器。它的灵活性使我们能够找到更好的解决方案，并减少拉曼泵的数量。此外，我们还利用该框架比较了四种利用混合光纤放大的多波段传输系统的潜力。仿真结果表明，与使用 E 波段或交错数据通道和拉曼泵相比，使用 S 波段对 C + L 波段系统进行补充可提高系统总容量。
期刊介绍：
The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
