We report on a C-band transpacific transmission using capacity-approaching truncated probabilistic constellation shaping 64QAM (TPCS-64QAM), adaptive-rate FEC decoding and digital nonlinear compensation achieving 28 Tb/s over 13,419 km transmission at 5.6 b/s/Hz spectral efficiency demonstrating a record 376 Pb/s×km capacity-distance product.
