Abstract: An optical backplane interconnects logic assemblies in a computer system using optical fibers. The logic assembly is connected to a laser or LED for converting electrical signals from the logic assembly into the equivalent optical signals. The optical signals are transmitted along the optical fibers to another logic assembly. The optical backplane comprises a mainframe rail for mounting to one end of the logic assembly, a connector attached to the mainframe rail, and an optical coupler mated with the connector. The optical coupler and connector having matching vee grooves for supporting and aligning the optical fibers.

Abstract: An electrical backplane makes high density electrical connections with logic boards in a computer system. The electrical backplane is comprised of an assembly pressure connector and a connector interconnect board that connects the logic boards to external wiring. The assembly pressure connector has electrical contact bumps on its surfaces for making electrical connections with contact points on the surface of the logic boards. The assembly pressure connector prevents the permanent deformation of its electrical contact bumps by using resilient bumps. The resilient bumps are formed from the end portions of interconnecting wires extending through the assembly pressure connector. The interconnecting wires are bent in the shape of a leaf spring. Thus, the wires are compressed within the elastic range of their composing material and are not permanently deformed by the force applied to the assembly pressure connector.
