Abstract
A balanced-line transmission cable is disclosed for use in a communications system of the type having a differential driver which transmits a differential output in the form of two output voltage signals which are transmitted to two corresponding inputs of a differential receiver which produces an output proportional to the difference between the two input voltage signals. A woven balanced line transmission cable includes a plurality of balanced-line signal conductor pairs each pair consisting of first and second signal transmission wires laterally spaced closely adjacent one another and lying generally parallel with one another in the cable. The first and second signal transmission wires transmit one each of the two voltages for input into the differential receiver. A plurality of fiber warp and weft yarns are interwoven in the cable with the signal conductor wire pairs fixing the lateral spacing and parallel alignment of the first and second signal transmission wires. The first and second signal transmission wires are woven in parallel vertical planes to yield a desired vertical displacement relative to one another in the cable providing a desired impedance value. A ground conduc…
