Neural Network Assisted Geometric Shaping for 800Gbit/s and 1Tbit/s Optical Transmission

End-to-end learning for amplified and unamplified links including binary-mapping is proposed to improve the performance of optical coherent systems. 1.0dB and 1.2dB gains are demonstrated on coherent 92GbaudDP-32QAM 800Gb/s and 82GbaudDP-128QAM 1Tb/s measurements, respectively.
