Just-in-time Restoration with Distributed Fiber Sensing in Metropolitan Optical Networks
arXiv:2606.09533v1 Announce Type: new Abstract: Distributed Fiber Sensing (DFS) leverages optical backscattering signals to predict failure events and enable just-in-time restoration in metropolitan optical networks, i.e., without optical amplifiers. In this paper, we study the effectiveness of proactive restoration based on DFS information in all-optical networks, while considering different sensing devices' capabilities. We evaluate whether restoration can be provisioned just-in-time...
Deployed trusted-node quantum key distribution over 300 km with a multi-core fiber access link
Announce Type: cross Abstract: Quantum key distribution (QKD) is increasingly considered for deployment in realistic communication networks, where long distances, heterogeneous fiber infrastructure, and coexistence with classical traffic present substantial challenges. Here, we demonstrate trusted-node QKD between Link\"oping University and the Stockholm hub of the Swedish national quantum communication infrastructure over 270 km of deployed single-mode fiber, extended by a 33 km multi-core...
