The beyond 5G transmission scenario requires new and cost/power-effective solutions for mid/long term evolution while preserving the growing capacity per optical interfaces and cards. Under the Beyond 5G paradigm (i.e., beyond first focused and standalone 5G trials), the network should be capable of supporting massive small cell deployments, as well as the widespread end-to-end (E2E) support to heterogeneous use cases with considerably different requirements in terms of connectivity, latency and

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
