1. An information handling system having a cable assembly, the information handling system comprising:a printed circuit board having a first surface and a second surface opposed to the first surface;
a first post and a second post extending from one side of the printed circuit board (PCB) to define a slot within the one side of the PCB;
a first signal line that terminates into a first signal pad, a second signal line that terminates into a second signal pad, and two ground lines, each terminating into a respective one of a first ground pad and a second ground pad that extends onto a respective one of the first post and the second post, each of the first signal line, second signal line, and two ground lines coupled to the first surface;
a first cable having a first signal wire at least partially covered by a first insulator, a second signal wire at least partially covered by a second insulator, and a first ground shield extending around an exterior of and at least partially covering the first and second insulators, a first end of the first cable mounted in the slot between the first and second posts;
an outer insulator that partially covers the ground shield; and
a first conductive attachment coupling the first signal wire to the first signal pad, a second conductive attachment coupling the second signal wire to the second signal pad, and a third conductive attachment coupling the first ground shield to the first ground pad.
