摘要： A data cable includes a plurality of cores each having a conductor surrounded by core insulation, providing the cores with a plurality of prescribed telecommunications transmission parameters. The core insulation includes a plurality of flame-retardant layers having a mineral, electrically insulating and flame-resistant first material, for maintaining functional integrity in the event of fire.

摘要： A data cable for high-speed data transmissions includes at least one wire pair formed of wires extending in a longitudinal direction and being surrounded by a shielding foil to form a pair shielding. A dielectric intermediate film or foil having a varying lay length is spun around the wire pair between the shielding foil and the wire pair, in order to effectively avoid a damping peak at high transmission frequencies.

摘要： A data cable for high-speed data transmission at signal frequencies of >10 GHz includes at least one core pair which is surrounded by a film-shaped pair shield having an inner shielding film and an outer shielding film which, are in electrical contact with one another and in which the inner shielding film is wound around the core pair. By virtue of this measure, an undesired resonance effect is avoided which, in previously wound pair shields, has not allowed use for relatively high signal frequencies. At the same time, an undesired common-mode signal, which would occur in the case of a longitudinally folded shielding film, is thus suppressed.
