Abstract
With the rapid development of cloud computing, video, smart home, and Internet of things (IoT), the bandwidth requirements for communications networks are also greatly increasing. The internet is facing new demands and challenges. Space Division Multiplexing (SDM) is an approach to increase the channel bandwidth capacity to explore potential spectrum resources in the spatial dimension with a multi-core fiber (MCF). Thus, this paper mainly proposes a spectrum-efficiency VON mapping approach with the inter-core crosstalk to reduce the spectrum occupancy and the inter-core crosstalk values in Space Division Multiplexing Elastic Optical Data Center Networks (SDM-EODCNs). Simulation results show that the proposed VON approach can efficiently reduce the spectrum occupancy rate and average inter-core crosstalk.
