Abstract

A data carrying cable to connect computing devices includes a first cable portion including a first conductor having a circular cross-section and a first gauge. A first port connector is connected to one end of the first cable portion. A second cable portion includes a second conductor having a circular cross-section and a second gauge that is different than the first gauge. The first conductor and the second conductor are arranged in series and are configured to carry a data signal between the computing devices.
