Abstract

A cable for high speed data communications and methods for manufacturing such cable are disclosed, the cable including a first inner conductor enclosed by a first dielectric layer and a second inner conductor enclosed by a second dielectric layer. The cable also includes conductive shield material wrapped in a rotational direction at a rate along and about the longitudinal axis around the inner conductors and the dielectric layers, including overlapped wraps of the conductive shield material along and about the longitudinal axis, the conductive shield material having a variable width. Transmitting signals on the cable including transmitting a balanced signal characterized by a frequency in the range of 7-9 gigahertz on the cable.
