Spatial Division Multiplexing (SDM) arises as the only solution to overcome the capacity limits of single-mode optical fibres (SMFs). Among the different SDM flavours, Multi-Core Fibres (MCFs) are gaining interest thanks to their low inter-core crosstalk (XT). In this context, Flex-Grid is envisioned as the technology that enables the efficient allocation of connections in SDM-based optical networks. Despite the benefits that the combination of Flex-Grid/SDM brings, the necessary guard-bands between connections can limit the performance, especially when allocating spatial super channels. In this paper, we evaluate the influence of the guard-band width on the performance of dynamic Flex-Grid/SDM optical networks when allocating spatial super-channel connections. The obtained results reveal that significant improvements can be achieved for reduced guard-band requirements.
