Compliant to the latest VITA 46 specifications, a 3U six-slot VPX backplane features a twisted-ring topology to enable the use of mezzanines like XMC as well as allow for more I/O pins than mesh topology. Two channels at the top of the J1 connector can be used for Gigabit Ethernet traffic in a fat pipe (4x bidirectional links).
The remaining channels in J1—together with those in the J2—leave 24 XAUI-capable ports that can be used entirely for rear-panel I/O. The 24 thin-pipe (one or two bidirectional links) channels remaining can be used by a PMC or XMC mezzanine or simply allow the 3U VPX modules to interface with external equipment, networks, displays, or storage systems. (Less than $1,500—4 to 6 weeks ARO.)
