Optical Data Link
The Hi-SIDE optical data link is a third-generation system developed within the OSIRIS (Optical Space Infrared Downlink System) programme. OSIRIS aims to develop experimental free space optical (FSO) communication systems optimized for small satellites.
Developed by DLR in cooperation with TESAT, the Hi-SIDE optical terminal system supports data link rates of up to 8Gbps with optical downlink rates of 10Gbps. Furthermore, the system is compatible with the SpaceFibre Standard and is a reference design for the emerging O3K CCSDS Standard for optical downlinks.
