“…The highest capacity is 2.15 Pbit/s (22-core SM-MCF, 31 km) [19] and 2.05 Pbit/s (19 core x 6 mode FM-MCF, 9.8 km) [29] as described earlier while the highest spatial multiplicity is over 100 (108 (36 core x 3 mode), 114 (19 core x 6 mode)). The largest capacity-distance product has already achieved more than one Ebit/s-km [26], [27], and has reached 4.59 Ebit/s-km recently [56]. Figures 12, 13, 14 show capacity per fiber, spatial multiplicity, aggregate SE vs. transmission distance, respectively.…”

“…Recently, there has been resurgence in the use of higher order modulation formats mainly attributed to the improvements in the electronic capabilities of digital-to-analog converters and signal processing techniques [4][5][6]. Well known formats such as QPSK, 8, 16 and 32 QAM have become straightforward to generate.…”

“…Hence, the ongoing rapid development of spacedivision multiplexing (SDM) transmission systems is expected to provide a viable strategy to increasing capacity of optical links. To support SDM, emerging transmission systems primarily employ multiple single-mode cores [4,5], multi-mode transmission [6,7], or a combination of both spatial aspects [8,9]. In this work, note that we employ a specific case of multi-mode transmission by exploiting 3 linearly polarized (LP) modes ; LP 01 , LP 11a and LP 11b which are excited and co-propagated in a few-mode fiber (FMF) transmission system.…”

Abstract:We experimentally verify the advantage of employing advanced coding schemes such as space-time coding and 4 dimensional modulation formats to enhance the transmission performance of a 3-mode transmission system. The performance gain of space-time block codes for extending the optical signal-to-noise ratio tolerance in multiple-input multiple-output optical coherent spatial division multiplexing transmission systems with respect to single-mode transmission performance are evaluated. By exploiting the spatial diversity that few-mode-fibers offer, with respect to single mode fiber back-to-back performance, significant OSNR gains of 3.2, 4.1, 4.9, and 6.8 dB at the hard-decision forward error correcting limit are demonstrated for DP-QPSK 8, 16 and 32 QAM, respectively. Furthermore, by employing 4D constellations, 6 × 28Gbaud 128 set partitioned quadrature amplitude modulation is shown to outperform conventional 8 QAM transmission performance, whilst carrying an additional 0.5 bit/symbol.

“…The overall input power of conventional single-core fiber transmission is under the fiber fuse transmission threshold value (1.2-1.4 W) [27]. On the other hand, MCF transmission with higher optical power has been demonstrated [12], [21], [22]. For example, we conducted 1 Pb/s 52 km MCF transmission with about 1.1 watts of optical signal power [12].…”

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.
