Node Architectures for High-Capacity Multi-band Over Space Division Multiplexed (MBoSDM) Optical Networks

This research considers the evolution of optical networks and the rising difficulties linked to managing optical signal switching within the network, especially when dealing with multi-band over spatial division multiplexing (MBoSDM) systems. We put forward three unique node architectures. Each node’s complexity is scrutinized and compared with a standard node architecture, offering valuable perspectives on potential obstacles in future optical networks. The work further investigates the advantages of employing fibre-core switching, a method that capitalizes on the reality that multiple spatial paths will link the same nodes, and traffic volume may allow to avoid individual channel demultiplexing/multiplexing at every node of the network. The results of this study not only enhance our comprehension of node architectures and fibre-core switching but also lay the groundwork for more effective and resilient optical communication networks.
