Patent ID: 10043599

Abstract:
A multi-core cable includes at least two coaxial wire pairs, each of the coaxial wire pairs including two coaxial wires being arranged side by side in contact with each other, each of the coaxial wires including a center conductor, an insulator, an outer conductor and a jacket, the outer conductor including an inner layer portion formed by thin metal wires being helically wrapped, and an outer layer portion formed by a metal resin tape being helically wrapped around the inner layer portion. A wrapping direction of the thin metal wires of the inner layer portion is opposite to a wrapping direction of the metal resin tape of the outer layer portion. An angle in the wrapping direction of the metal resin tape with respect to the wrapping direction of the thin metal wires is in a range of 30° or more but 90° or less. A cross-talk between the coaxial wire pairs is equal to or less than −40 dB.
