摘要： Optical networks have been an (often underestimated) enabler of our hyper-connected societies, as they fulfil the key role of reliably carrying massive amounts of data across medium to long distances. The relentless demand for traffic and the potential impact of massive AI workloads on inter data center traffic requirements, are setting the stage for even higher capacity needs. However, since we already ripped most of the spectral efficiency improvements of the “coherent revolution” that started back in 2010, this time around more capacity will mean more spectrum. Exploiting wideband transmission is an appealing approach to postpone costly roll out of new optical fibers, particularly for service providers that are fiber constrained. This talk will overview solutions to exploit more transmission bands, highlighting the associated technical challenges, with a specific focus on reliability, and discussing potential mitigation strategies. Moreover, it will also address recent developments on using machine learning techniques and real-time monitoring data for early failure detection and proactive restoration, which can play an important role in cost-effectively improving service availability in optical networks.
