  • Typical cables for data transmission are, for example, more or less rigid coaxial cables, in which an inner conductor is surrounded by a cylindrical outer conductor, and, on the other hand, more flexible, differential (symmetrical) cables, in which positive and negative conductors are laid parallel to one another.

  • the core idea of the present invention is to have realized that it is possible to more efficiently enable high-frequency data transmission in a high-speed data cable, resulting in lower attenuation, especially at high frequencies.
  • the high-speed Data cable includes at least one wire pair, with a conductive shield surrounding the wires.
  • the conductive shielding results in an increased immunity to interference of the cable, which, inter alia, a faster data transmission is possible.
  • An insulating cable sheath encloses the conductive shielding and protects the cable against mechanical stress and corrosion.
  • Each of the wires comprises at least three electrical conductors insulated from one another, wherein the conductors are arranged to extend in an equidistant manner to a longitudinal central axis of the respective core.
  • the skin effect refers to the narrowing of the signal current in ever smaller space (near or at the conductor surface) at higher frequencies. Effectively, the conductor cross-section available for the current transport decreases or the ohmic resistance increases with increasing frequency. The skin effect thus leads to a high signal attenuation, especially at high frequencies.
