Record 46.2Pbit · km/s real-time optical transmission over 1050-km G.652.D SSMF utilizing 400-Gbit/s transponder with a symbol rate of 91.6-GBaud

We experimentally demonstrated a 110-channel 44-Tbit/s real-time wavelength division multiplexing (WDM) transmission over 1050-km G.652.D single-mode fiber (SMF) utilizing 400-Gbit/s transponders with a symbol rate of 91.6GBaud and 11-THz commercial C+L band Erbium-doped fiber amplifiers (EDFAs). To the best of our knowledge, this is a record capacity distance product $(46.2-Pbit\cdot km/s)$ in the real-time optical transmission systems.
