Transoceanic transmission of dual-carrier 400G DP-8QAM at 121.2km span length with EDFA-only

400-Gb/s dual-carrier DP-8QAM transmission over 6,787 km is reported at 121.2km span length, the longest to date with EDFA only. Spectral efficiency of 4.54 b/s/Hz is achieved thanks to Nyquist shaping and nonlinear compensation techniques.
