800G Transmission at 100W Output Power - Assessing the Feasibility of Optical Satellite Feeder Links

We present advancements in free-space optical communication for satellite-ground networks. Using advanced atmospheric-turbulence-mitigation techniques, we tested new modulation formats at low-received optical powers at data rates of up to 1Tbit/s and transmitted output powers of up to 100 Watts across linear, free-space links of up to 53km.
