Single-Wavelength and Single-Photodiode 700 Gb/s Entropy-Loaded PS-256-QAM and 200-GBaud PS-PAM-16 Transmission over 10-km SMF

We demonstrate the transmission over 10.2-km SMF of intensity-modulated and direct-detected (IM-DD) signals at record 700.4 Gb/s line rate and record 538.8 Gb/s net rate with entropy loaded PS-256-QAM signals, and 200-GBaud PS-PAM-16 signals with 650 Gb/s line rate and 484.5 Gb/s net rate.
