空分复用（SDM）作为克服单模光纤（SMF）容量限制的唯一解决方案而出现。在不同的SDM风格中，多芯光纤（MCF）由于其低芯间串扰（XT）而受到关注。在这种情况下，Flex-Grid被设想为能够在基于SDM的光网络中有效分配连接的技术。尽管Flex-Grid/SDM的组合带来了好处，但连接之间必要的保护带会限制性能，特别是在分配空间超级信道时。在本文中，我们评估的动态Flex-Grid/SDM光网络的性能时，分配空间超级信道连接的保护带宽的影响。所得到的结果表明，可以实现显着的改善，降低保护频带的要求。
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.
