9 Tb/s Transmission using 29 mW Optical Pump Power per EDFA with 1.24 Tb/s/W Power Efficiency over 15,050 km

We transmit 143x32.6 GBd 8D-QPSK signal over 15,050 km with EDFAs consuming 29 mW of 980 nm-pump power. We experimentally achieve record power efficiencies from 6.5 to 1.24 Tb/s/W for transmission distances ranging from 6,020 to 15,050 km respectively.
