SpaceFibre is a very high-speed serial data-link being developed by the University of Dundee for the
European Space Agency (ESA) which is intended for use in data-handling networks for high data-rate
payloads. SpaceFibre is able to operate over fibre-optic and electrical cable and supports data rates of 2 Gbit/s
in the near future and up to 5 Gbit/s long-term. It aims to complement the capabilities of the widely used
SpaceWire onboard networking standard: improving the data rate by a factor of 12.5, reducing the cable
mass and providing galvanic isolation. Multi-laning improves the data-rate further to well over 20 Gbits/s.

This paper provides an introduction to SpaceFibre and then describes the work being done by various
organisations to simulate, implement, test and validate SpaceFibre.
