TL;DR: In this article, the authors demonstrate 140.7-Tbit/s, 7,326-km transmission of 7×201-channel 25GHz-spaced Super-Nyquist-WDM 100-Gbit/S optical signals using seven-core fiber and full C-band EDFAs, achieving a capacity-distance product of 1.03 Exabit/s·km.

TL;DR: Super-Nyquist-WDM transmission technique, where optical signals with duobinary-pulse shaping can be wavelength-multiplexed with frequency spacing of below baudrate, is shown, one of the first reports of high-capacity transmission experiments with capacity-distance product in excess of 1 Exabit/s · km.

TL;DR: The first 7-core multicore erbium-doped fiber amplified (MC-EDFA) transmission of 40 x 128-Gbit/s PDM-QPSK signals over 6,160-km 7- core multicore fiber (MCF) is demonstrated and the feasibility of MC-ED FA repeatered systems for trans-oceanic transmission is confirmed.

TL;DR: In this paper, a compact fiber bundle type fan-out for multicore fiber by using capillary action of adhesive was developed, which demonstrated low splice loss less than 0.35dB and low cross-talk less than −64dB in all cores.

TL;DR: The feasibility of 100-Tbit/s-class trans-oceanic SDM transmission is confirmed and seven-core fiber spans with seven- core full C-band EDFAs are used.
