Abstract
iXblue and Airbus Defence and Space developed a space-grade optical transceiver to increase communication rate between geostationary (GEO) or low earth orbit (LEO) satellites and earth. First demonstration model which will be launched early 2023 on a geostationary satellite possesses 2 downlink channels working at 10 Gb/s in non-return to zero differential phase shift keying (NRZ-DPSK), and 3 uplink demodulation channels. Two of them are dedicated to analog signals around 1 GHz, and one is dedicated for digital on-off keying (OOK) signal at 10 Gb/s.
