SpaceFibre is an high speed communication protocol suitable for on board satellite communication. It is the successor of the SpaceWire protocol, allowing higher data rates (up to 6.25Gbps per lane), maintaining also compatibility with it. The SpaceFibre standard has recently passed ECSS public review. At the moment however several IP cores are already available on the market, together with dedicated hardware products. The work presented in this paper aims at verifying the interoperability of the different devices available on the market.
