10 Gbauds digital optical link and analog link from/to geostationary satellite

Architecture of a 10 Gbauds link between new high complexity optical ground station suitable for feeder link and a geo-stationary satellite is described. Such link is tested in laboratory environment with emulation of power fluctuations representative of the power budget between the optical ground station and the satellite. The software and hardware developed reach the expected performance and the system performance model is demonstrated to be accurate at 1 dB.
