“…5 Few-mode multicore fiber MDM over FMF is another candidate for SDM. A largecapacity MDM transmission experiment of 72.7 Tb/s, which is close to the maximum record of 102.3 Tb/s on a single-core SMF [73], has been demonstrated [74]. Many types of FMFs have been proposed to increase the number of modes, to optimize mode-coupling, and to reduce differential mode group delay (DMD) [75][76][77][78][79].…”

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.

“…Multi-level transmission systems have been investigated to increase the transmission capacity of optical fiber [23], [24]. QAM (Quadrature Amplitude Modulation) format utilizes the amplitude and phase of light and so can improve the frequency utilization efficiency, and increase the transmission capacity in a limited bandwidth.…”

SUMMARYThe paper presents ultra-high-capacity transmission technologies based on multi-core space-division-multiplexing. In order to realize high-capacity multi-core fiber (MCF) transmission, investigation of low crosstalk fiber and connection technology is important, and high-density signal generation using multilevel modulation and crosstalk management are also key technologies. 1 Pb/s multi-core fiber transmission experiment using space-division-multiplexing is also described.

“…For example, coherent modulation using optical phases was suggested to increase spectral efficiency and total capacity; however, such a transmission system would significantly suffer from fiber nonlinearity. The limit capacity of SSMF is generally considered to be 100 Tb/s [4,5,6]. Because it is a potential candidate of breakthrough technology against the capacity crunch, space-division multiplexing (SDM) was investigated (Fig.…”

SUMMARYThe potential transmission capacity of a standard single-mode fiber peaks at around 100 Tb/s owing to fiber nonlinearity and the bandwidth limitation of amplifiers. As the last frontier of multiplexing, space-division multiplexing (SDM) has been studied intensively in recent years. Although there is still time to deploy such a novel fiber communication infrastructure; basic research on SDM has been carried out. Therefore, a comprehensive review is worthwhile at this time toward further practical investigations.
