A cable bypass assembly is disclosed for use in providing a high speed transmission line for connecting a board mounted connector of an electronic device to a chip on the device board. The bypass cable assembly has a structure that permits it, where it is terminated to the board mounted connector and the chip member, or closely proximate thereto to replicate closely the geometry of the cable. The connector terminals are arranged in alignment with the cable signal conductors and shield extensions are provided so that shielding can be provided up to and over the termination between the cable signal conductors and the board connector terminal tails. Likewise, a similar termination structure is provided at the opposite end of the cable where a pair of terminals are supported by a second connector body and enclosed in a shield collar. The shield collar has an extension that engages the second end of the cable.
