Record Long-Haul Transmission with FIFO-Less Multicore EDFA Over 125-μm Cladding MCF

The record 203 Tb/s and 102 Tb/s SDM transmission enabled by
$\mathrm{C}+\mathrm{L}$
band FIFO-less MC-EDFA over 3105 km and 7245 km weakly-coupled 4-core MCF with
$125-\mu \mathrm{m}$
cladding diameter was first experimentally demonstrated using PCS-16QAM and PDM-QPSK, respectively. Effective cost was achieved by G.652-compatible MCF and fully-integrated-components multicore EDFA.
