Abstract

A cabled midplane interconnect system includes a cabled midplane interconnect having a first connection and a second connection. A first circuit board has a third connection configured to be coupled to the first connection. A second circuit board has a fourth connection configured to be coupled to the second connection. The connection orientations are assigned such that a midplane cable, having a plurality of conductors, couples the first connection to the second connection so that none of the plurality of conductors crosses another of the plurality of conductors.

First claim

What is claimed is:

1 . A cabled midplane interconnect, comprising:
a first connector having a first connection orientation including a first plurality of transmit connections and a first plurality of receive connections; a second connector having a second connection orientation including a second plurality of transmit connections and a second plurality of receive connections; and a cable comprising a plurality of conductors, each conductor coupling a connection in the first connector with a corresponding connection in the second connector, wherein the second connection orientation is configured such that the first plurality of transmit connections is coupled to the second plurality of receive connections and the first plurality of receive connections is coupled to the second plurality of transmit connections such that none of the plurality of conductors crosses another one of the plurality of conductors.

2 . The cabled midplane interconnect of claim 1 , wherein a total width of the plurality of conductors does not exceed a pitch of the first or second connectors.

3 . The cabled midplane interconnect of claim 1 , wherein the first connector is disposed on the midplane interconnect directly opposite the second connector.

4 . The cabled midplane interconnect of claim 1 , wherein the first connector is disposed on the midplane interconnect diagonally opposite the second connector.

5 . The cabled midplane interconnect of claim 1 , wherein the plurality of conductors comprise one or more of individual wires, coaxial cable, twisted shielded wires, and/or optical fiber.

6 . A method for producing a cabled midplane interconnect, the method comprising:
providing a midplane interconnect having a first connector and a second connector; and assigning a first connection orientation to the first connector and a second connection orientation to the second connector such that transmit and receive connections on first and second circuit boards are connected through a plurality of conductors of a midplane interconnect cable without any of the plurality of conductors overlapping another of the plurality of conductors.

7 . The method of claim 6 , further comprising:
assigning a transmit connection directly across the midplane interconnect from the first connector to a receive connection on the second connector, and assigning a receive connection directly across the midplane interconnect from the first connector to a transmit connection on the second connector.

8 . The method of claim 6 , further comprising:
assigning a transmit connection diagonally across the midplane interconnect from the first connector to a receive connection on the second connector; and assigning a receive connection diagonally across the midplane interconnect from the first connector to a transmit connection on the second connector.

9 . The method of claim 6 , wherein assigning the first connection orientation to the first connector and the second connection orientation to the second connector comprises assigning the first connection orientation to the first connector and the second connection orientation to the second connector such that the midplane interconnect cable is not twisted.

10 . The method of claim 6 , wherein assigning the first connection orientation to the first connector and the second connection orientation to the second connector comprises assigning the first connection orientation to the first connector and the second connection orientation to the second connector such that the midplane interconnect cable has a width that is less than or equal to a pitch of the first or second connectors.

11 . The method of claim 6 , further comprising providing the midplane interconnect cable configured to couple the first connector to the second connector such that the cable is not twisted.
