Net bitrate of >1.3-Tb/s/λ transmission over 80 km with transmitter-side semiconductor optical amplifier

We evaluated 144-GBaud 64QAM signal characteristics with transmitter-side SOA. Back-toback experiments demonstrated up to 1.38-Tb/s/λ net bitrate with optimized SOA input powers and injection currents. We also performed 80-km SMF transmission between 1530.529 and 1564.067 nm, achieving >1.3-Tb/s/λ net bitrate with the optimum SOA conditions.
