30.58 Tb/s transmission over 7,230 km using PDM half 4D-16QAM coded modulation with 6.1 b/s/Hz spectral efficiency

We transmit 30.58 Tb/s data (294×104 Gb/s) over 7,230 km in 40 nm bandwidth with 6.1 b/s/Hz spectral efficiency. We use PDM half-4D-16QAM coded modulation to achieve the highest reported capacity-distance product of 221 Pb/s·km.
