SpaceFibre is the next generation of SpaceWire network technology for spacecraft on-board data-handling. It runs over electrical or fibre-optic cables, operates at very high data rates, provide in-built quality of service (QoS) and fault detection, isolation and recovery (FDIR) capabilities. This paper introduces SpaceFibre, describes its position as a state-of-the-art network technology for space applications, details it principal capabilities, introduces some of the SpaceFibre components that are available now or will be in the near future, and describes the SpaceFibre test and development equipment available from STAR-Dundee.
