XAUI allows XGMII to reach an extended distance by using a XGXS layer at each end of the MAC to PHY link, operating over four Serdes lanes. 10GBASE-KR is a single lane Serdes backplane ethernet connection method with autonegotiation on the link. Some PHYs use this to connect to the ethernet interface at 10G speeds, switching to other connection types when utilising slower speeds. 10GBASE-KR is also used for XFI and SFI to connect to XFP and SFP fiber modules.
