Fabrics
The Base Interface can only be 10BASE-T, 100BASE-TX, or 1000BASE-T Ethernet. Since all boards and hubs are required to support one of these interfaces there is always a network connection to the boards.
The Fabric is commonly SerDes Gigabit Ethernet, but can also be Fibre Channel, XAUI 10-Gigabit Ethernet, InfiniBand, PCI Express, or Serial RapidIO. Any Fabric that can use the point-to-point 100 Ω differential signals can be used with an AdvancedTCA backplane.
The PICMG 3.1 Ethernet/Fibre Channel specification has been revised to include IEEE 40GBASE-KR4 signaling to the existing IEEE 10GBASE-KX4, IEEE 10GBASE-KR, and XAUI signaling. Switch boards using the 40GBASE-KR4 signaling were successfully tested in four different manufacturer's shelves at a recent ATCA Interoperability Workshop.

Famous quotes containing the word fabrics:
“Egotism is a kind of buckram that gives momentary strength and concentration to men, and seems to be much used in Nature for fabrics in which local and spasmodic energy is required.”
—Ralph Waldo Emerson (1803–1882)
