Enabling Technologies for Optical Data Center Networks: Spatial Division Multiplexing [PDF]

Journal of Lightwave Technology, 2020
With the continuously growing popularity of cloud services, the traffic volume inside the data centers is dramatically increasing. As a result, a scalable and efficient infrastructure for data center networks (DCNs) is required. The current optical DCNs using either individual fibers or fiber ribbons are costly, bulky, hard to manage, and not scalable.
