Abstract

Method, apparatus, and electrical cable for high-speed connections. The apparatus can include an electrical cable, a wire sorter, an electrical mating paddle, and a cable assembly. The wire sorter can be coupled to an end of the electrical cable, and configured to receive wires extending from the end of the electrical cable and position the wires relative to one another in a predetermined arrangement to yield sorted wires. The electrical mating paddle card can then be coupled to the sorted wires according to the predetermined arrangement. The cable assembly can be configured to house the wire sorter and at least a portion of the wires. Moreover, the cable assembly can include a hot-melt injection chamber configured to at least partially immobilize the wires relative to the cable assembly when hot-melt is injected into the hot-melt injection chamber.
