High density cabled midplanes and backplanes

摘要

A cabled midplane includes a first support plate along a plane between a first connector set and a second connector set that connect to line cards on either side of the cabled midplane. The first connector set and the second connector set include connector slices. A wiring sub-layer includes cable slices to provide a connection between the first connector slice of a connector of the first connector set to the first connector slice of a connector of the second connector set, such that the first wiring sub-layer connects each connector of the first connector set, through one cable slice, to a connector of the second connector set. Additional wiring sub-layers are added, and a second support plate, parallel to the first support plate, is provided to encase and support the wiring sub-layers between the first support plate and the second support plate. Other apparatuses and methods are described.

1. A cabled midplane comprising:
a first support plate along a plane between a first connector set and a second connector set, the first connector set including a plurality of connectors to connect to respective line cards on a first side of the cabled midplane, the second connector set including a plurality of connectors to connect to respective line cards on a second side of the cabled midplane, connectors of the first connector set and the second connector set including a plurality of connector slices, the plurality of connector slices including at least a first connector slice that is a first distance along a first axis from the first support plate and a second connector slice that is a second distance, further than the first distance, along the first axis from the first support plate; a first wiring sub-layer including a first plurality of cable slices mounted on the first support plate, each cable slice of the first plurality of cable slices to provide a connection between the first connector slice of a connector of the first connector set to the first connector slice of a connector of the second connector set, such that the first wiring sub-layer connects each connector of the first connector set, through one cable slice, to a connector of the second connector set; at least a second wiring sub-layer including a second plurality of cable slices, each cable slice of the second plurality of cable slices to provide a connection between the second connector slice of a connector of the first connector set to the second connector slice of a connector of the second connector set, such that the second wiring sub-layer connects each connector of the first connector set, through one cable slice, to a connector of the second connector set; and a second support plate, parallel to the first support plate, to encase the first wiring sub-layer and the second wiring sub-layer between the second support plate and the first support plate and to form a first wiring layer of the cabled midplane.
