Basically, you can think of the SFP+ to BASE-T module as a media converter - it receives 10GBASE-R on one end, and produces 10GBASE-T on the other end, and vise versa. 4. 29, 2002, both of which are incorporated herein by reference. Note: 10GBASE-R is the single-channel protocol that. The first input of data is encoded into four outputs of encoded data. What is not symmetric is that the XGXS/XAUI/XGXS is not intended to sit "in the middle" of the XGMII so the notion of XAUI as a XGMII "extender" is not altogether appropriate for those individuals that can only envision an extender as something that goes in the middle. Currently I'm using a LS1046ARDB board and trying to use the SFP+ Port in SGMII protocol instead of XFI. The CoreUSXGMII (Universal Serial Media Independent Interface) IP is used to carry single network port over a single SERDES between the MAC and the PHY for Multi-Gigabit.
