“…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.…”
