Workshop Description Multi-band (MB) expands the available capacity of optical fibres beyond traditional C and/or C+L bands by enabling transmission within S, E, and O bands – translating into a potential 10x capacity increase. MB networking raises challenges from both system and network perspectives. From the point of view of the former, MB networks require new key components, such as optical amplifiers, transceivers, and possibly MB reconfigurable add/drop multiplexers (MB

“LPsec: A Fast and Secure Cryptographic System for Optical Connections,” by Iqbal, L. Velasco, N. Costa, A. Napoli, J. Pedro, and M. Ruiz, IEEE/OPTICA Journal of Optical Communications and Networking (JOCN), 2022. We propose Light Path SECurity (LPsec), a secure cryptographic solution for optical connections that involves fast data encryption using stream ciphers and key exchange using Diffie-Hellman (DH) protocol through the optical channel.

“Deep Learning -based Real-Time Analysis of Lightpath Optical Constellations [Invited],” by Ruiz, D. Sequeira, and L. Velasco, IEEE/OPTICA Journal of Optical Communications and Networking (JOCN), vol. 14, pp. C70-C81, 2022. In-phase (I) and quadrature (Q) constellation analysis enables deep understanding of the characteristics of lightpaths. We present methods based on deep learning. https://opg.optica.org/jocn/abstract.cfm?uri=jocn-14-6-C70

“On the Benefits of Point-to-Multipoint Coherent Optics for Multilayer Capacity Planning in Ring Networks with Varying Traffic Profiles” by P. Pavon-Marino, N. Skorin-kapov, M. V. Bueno-Delgado, J. Back, and A. Napoli Abstract: Point-to-Multipoint (P2MP) coherent optics using Digital Subcarrier Multiplexing (DSCM) have recently been proposed as a promising new technology to reduce the cost and complexity of optical transport networks,particularly those in metro aggregation scenarios with Hub-and-Spoke (H&S) traffic patterns

“Evaluation of Deep Reinforcement Learning for Restoration in Optical Networks” By C. Hern´andez-Chulde, R. Casellas, R. Mart´ınez, R. Vilalta, R. Munoz – CTTC. Abstract: A deep reinforcement learning-based agent is presented to perform autonomous lightpath restoration upon a link failure event. The agent is evaluated against other heuristic algorithms under different traffic load and failure duration scenarios.
