“…In this experiment, the feasibility of MCF transmission with high pump power of 6.5 W per fiber was confirmed. The maximum transmission distance over MCFs so far was recorded by KDDI et al [63]. They have achieved 6160-km transmission over a seven-core HCPS MCF with a multicore EDFA.…”

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.

“…The total net capacity was 7.50 Tb/s and the capacity-distance product reached 20.2 Pb/s·km. In a simpler configuration, a 6160-km transmission distance was achieved by using 7-fold, 55 km of 7-core MCF [53,54]. A loop was configured simply by connecting each core in series.…”

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.

“…MDM transmission employing orbital angular momentum (OAM) modes [32] has also demonstrated where 400 Gb/s QPSK data was transmitted recently over 1.1 km [33]. SDM transmission utilizing MCFs with low crosstalk, on the other hand, have also seen many experimental demonstrations on high-capacity transmission of 100 Tb/s, 300 Tb/s up to 1 Pb/s, employing uncoupled 7-core, 19-core, and 12-core MCFs [34][35][36][37][38], respectively or long distance transmission over 1,000 km [39][40]. Multi-mode (MM) or multi-core (MC) optical amplifiers are strongly required for long-haul systems and should be major enablers to make SDM systems cost-effective and energy-efficient compared to present systems.…”
