“…Therefore, a practical and optimal solution is still being pursued. SM-MCF is much easier to achieve large capacity/longdistance transmission because single-mode propagation is stable and the increase in the core number directly reflects on the total capacity [20,21,22,23,24]. FM-MCF has a considerable potential of providing ultimate capacity and spatial channel counts [25,26,27,28,29,30]; however, the transmission system tends to be complex.…”

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.

“…Coupled MCFs supporting single transverse mode and multi transverse modes have been investigated for high power fiber laser applications [9,10], since they are able to be used as large-mode-area (LMA) fibers, while the coupled MCFs supporting a few supermodes can be used as few-mode fibers (FMFs) for large capacity transmission experiments with mode-division multiplexing (MDM) technique [11][12][13][14]. In terms of core arrangement in uncoupled MCFs, homogeneous MCFs with identical multiple cores [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] and heterogeneous MCFs with several kinds of different cores [31][32][33][34][35] have been reported. In addition, each core can be designed to support not only single mode but also few modes and multi modes, and they can be called single-mode MCF (SM-MCF), few-mode MCF (FM-MCF) [36][37][38][39][40][41][42], and multimode MCF (MM-MCF) [43], respectively.…”

In the uncoupled MCFs, high core density as well as low attenuation and large effective area, A eff , are important characteristics for utilizing MCFs as a transmission fiber to improve optical signal to noise ratio (OSNR) and SDM efficiency.…”

“…The RCMF is ratio between CMF of an MCF and a standard single-core SMF with A eff of 80 μm 2 at 1550-nm wavelength and cladding diameter of 125 μm. The reported maximum RCMF with large A eff of larger than 100 μm 2 and low 100-km crosstalk of smaller than -50 dB is 5.57 for 7-core fiber [27] and 4.70 for 12-core fiber [30], and the maximum number of incorporated cores in a single cladding is 19 [25] so far. The crosstalk in Table 1 is averaged value between two cores at 1550 nm after 100-km propagation.…”

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.

SUMMARYWe have proposed and developed new electro-optic modulators for the pre-equalization of signal distortion caused by the optical fiber chromatic dispersion effect. We found that the synthesis of an almost arbitrary impulse response function is obtainable by utilizing an electro-optic modulator composed of a Mach-Zehnder waveguide and travelling-wave electrodes on a ferro-electric material substrate with polarization-reversed structures. In this paper, the operational principle, design and simulation results of the pre-equalization modulator are presented. Some preliminary experimental results are also shown with future prospects.
