“…The advances in MCF fabrication enables higher spatial efficiency with a novel cross-section geometry design, such as two-pitch 10-core fiber [25], dual-ring 12-core fiber [26], and hexagonal 30-core fiber [27]. Linearly arrayed MCFs with core arrangements in a rectangular shape [28,39], as shown in Fig.…”

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. Spatial division multiplexing (SDM) based on multicore or multimode (few-mode) fibers is recognized as a promising technology to increase the spatial efficiency for optical DCNs, which opens a new way towards high capacity and scalability. This tutorial provides an overview of the components, transmission options, and interconnect architectures for SDM-based DCNs, as well as potential technical challenges and future directions. It also covers the co-existence of SDM and other multiplexing techniques, such as wavelength-division multiplexing and flexible spectrum multiplexing, in optical DCNs.

“…A few reported long-haul MCF transmission experiments have been achieved with core pumped MCEDFAs [1,2]. Another approach is based on the cladding pumping scheme in which all cores are simultaneously pumped using a single high power multi-mode LD [4][5][6]. The cladding pumped MC-EDFA allows to reduce the number of pump LDs and does not require fan-in/out devices to pump each core, compared to the core pumped MC-EDFA.…”

“…1(b). Various multi-core optical components, including fan-in/fanout [6][7][8][9], connectors [10], switches [11], WDM couplers and isolators [12], gain flattening filters [13], and Er-doped fiber amplifiers (EDFAs) [12,[14][15][16][17][18][19], have also been developed all over the world. In this paper, we summarize and review recent progress on MCF-based SDM components and related technologies.…”
