Abstract
A woven electrical transmission cable is disclosed having a controlled impedance and reduced signal interference characteristic in which the density of the signal conductors may be increased without widening the configuration of the cable. The cable (A, F, K) is woven in a tubular configuration wherein the signal conductors (10, 30, 34) are arranged and woven about the periphery of the cable with a vertical spacing component between the conductors. The signal conductors are arranged with ground conductors (12, 32, 36) on each side thereof in the form of clusters (D, E, G, H) in strata about the periphery of the cable. In a preferred form the cable (F, K) is woven in a flattened oval configuration wherein the clusters of conductors are arranged in spaced layers which are generally parallel. In practice, noisy lines and quiet lines may be placed in opposed layers for maximum reduction of signal interference.
