N×100Gbit/sWDM系统已经趋于成熟并逐渐开始引入规模商用。网络带宽的持续快速增长促使骨干光传送网在未来向更高的传输速率演进。本文分析了超100Gbit/s的关键技术.并对未来超100Gbit/s技术发展的路线选择进行了探讨。
N x 100Gbit/s WDM system has been gradually commercialized. Next-generation optical transmission systems are edging ever closer to forecasted capacity limits, due to the continuously growing internet bandwidth requirement. In this paper, we will discuss the key technologies for beyond 100Gbit/s, and outline how core networks might still be scaled to 400Gbit/s and beyond.
