High capacity transmission with a data rate over 10.66 Pb/s is demonstrated in a 13 km, 38-core-3-mode few-mode multi-core fiber. This was achieved with a single optical comb source to generate 368 × 24.5 GBaud 64- or 256-quadrature-amplitude-modula

We demonstrate multi-span transmission over 65 ( $5\times 13$ ) km few-mode multi-core fiber by transmitting $368\times 24.5$ GBaud C- and L-band signals with QPSK, 16- or 64 QAM modulation. We analyze each core-combination's transmission channel cha

We demonstrate transmission of 368-WDM-38-core-3-mode × 24.5-GBaud 64-and 256-QAM signals over 13 km. Record data-rate and spectral-efficiency of 1158.7 b/s/Hz were enabled by a low DMD 38-core-3-mode fiber with high uniformity amongst cores.

This paper describes a six-mode 19-core fiber with 114 spatial modes, which was designed and fabricated for weakly-coupled mode-division-multiplexed (MDM) transmission over uncoupled cores. The 19 identical graded-index cores were packed on a hexagon

Newly developed 125-μm-cladding coupled four-core fibers realized the record-low spatial mode dispersion (SMD) of 3.14 ± 0.17 ps/√km over C-band and the ultra-low attenuation of 0.158 dB/km at 1550 nm, both of which are the lowest ever reported a

We investigate the vibration sensitivity of spatially multiplexed links by measuring the mode-coupling dynamics of a four-core coupled-core fiber and a reference single-mode fiber. We show that the speed of dynamics increases with mode count.

We demonstrated simultaneous usage of 228 spatial channels (effectively) within a strand of fiber. We fabricated a 13-km 39-core 3-mode fiber and constructed a bi-directional space division multiplexing (SDM) transmission setup by using cascaded spat

Coupled-core multicore fibers provide significant advantages for long-haul high capacity fiber optics communication: Cores with large effective areas can be densely packed, and show a better tolerance to nonlinear effects compared to single-mode fibe

Loss and crosstalk variations of an indoor multi-core fiber (MCF) cable were evaluated during mechanical and thermal tests. Furthermore, for the first time, the crosstalk of the MCF in the straightened cable was observed. The results demonstrate opti
