“…The crosstalk of the MCF was somewhat large compared to other MCFs due to a tight core-to-core distance for 19-core packing within cladding diameter of 200 μm. NTT et al have demonstrated the transmission experiment whose capacity exceeded 1 Pb/s/fiber for the first time [64]. A 52.4-km 12-core MCF with a one-ring structure (ORS) shown in Figure 6A was used in this experiment.…”

Abstract:We experience Internet traffic growth of 100 times every 10 years. However, the capacity of existing standard single-mode fiber is approaching its fundamental limit regardless of significant realization of transmission technologies which allow for high spectral efficiencies. Space division multiplexing (SDM) based on multicore fibers (MCFs) has emerged as a solution to the problem of saturation of the capacity of optical transmission systems. This article presents the recent progress on the MCFs for future large capacity long-distance transmission systems. In MCFs, there is a tradeoff relationship between low crosstalk and high multiplicity, therefore the maximum number of cores and the core arrangement have to be carefully determined based on the required crosstalk level and core size. The state-of-the-art of fabricated MCFs and the transmission experiments using MCFs are reviewed. The current maximum capacity-distance product in MCF transmission is 368.2 (184.1+184.1) Pb/s/fiber km with the relative spatial efficiency of 4.7 compared with a standard single-mode fiber. In order to increase the spatial efficiency as well as the capacity-distance product further in MCFs, the possibility of heterogeneous MCFs and few-mode MCFs is also presented.

“…One proposed solution makes use of space-division multiplexing (SDM) to increase the capacity of fiber-optic communication networks at a reduced energy cost per transmitted bit [23][24][25][26]. The basic idea is to employ multimode fibers such that several WDM bit streams can be transmitted over different modes of the same fiber.…”

“…Similar to the case of WDM technology, the implementation of SDM requires not only new types of fibers but also many other active and passive optical components such as mode multiplexers/demultiplexers and fiber amplifiers that can amplify signals in all modes/cores simultaneously. A lot of progress has been made since 2010 in realizing such devices and many laboratory demonstrations have shown the potential of SDM for enhancing the system capacity [23][24][25][26]. .…”

“…Further increase in system capacity required the adoption of SDM. In a 2012 experiment, SDM was used to demonstrate data transmission at 1000 Tbit/s (or 1 Pbit/s) by employing a 12-core fiber [24]. Each fiber core carried 222 WDM channels, and each wavelength transmitted a 380-Gbit/s bit stream over a 52-km-long multicore fiber with a spectral efficiency of 7.6 bit/s/Hz.…”

“…In the last few years, multicore fiber (MCF) technology has been shown to be able to successfully achieve long-haul distances [2], high capacity transmission [3], and to potentially share components with the aim of reducing manufacturing costs [4]. Whereas the number of cores in MCF has increased over time [5], [6], one aspect remains largely unexplored: full integration of MCF systems.…”
