NDLI: Optical comb enabled flexible-bandwidth single-carrier frequency-division-multiplexed-based intra-data centre interconnect

Abstract	In this study, the authors propose a novel intra-data centre network (DCN) architecture based on cascaded micro-electro-mechanical system switches for dynamic DCN connectivity provisioning. Through combining the single-carrier frequency-division-multiplexed with the proposed architecture, this structure can achieve unprecedented flexibility in dealing with both mice and elephant flow in the DCN. Multiple-input multiple-output switching is experimentally demonstrated through intra- and inter-data centre switching scenarios. A numerical investigation is also performed to evaluate the performance of the fixed-grid transceivers, flex-grid transceivers and mixed-fixed/flex grid transceivers in the same switching scenario. The results show that the flex-grid transceivers significantly reduced the service latency and blocking probability compared to the fixed-grid transceivers. The proposed architecture would be better applied in the field of all-optical DCNs.
