The company’s latest 3U, six-slot OpenVPX backplane employs a twisted-ring routing topology. Compliant to VITA 65 specifications for OpenVPX, the backplane has configurable thin pipe links for distributed Gigabit Ethernet to slot one through slot five and two fat pipes for rear I/O. In slots one through five, any or all of the P1 thin pipes (x2 channels) assigned to the control channel star are reconfigurable as rear I/O by removing zero-Ohm SMT shunts.
