Conference Paper

This research considers the evolution of optical networks and the rising difficulties linked to man- aging 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.
