The data cable has two wire pairs which each have two wires which are surrounded by a pair shield. In addition to the pair shield, a planar or flat shielding element which does not surround the core pairs and makes contact with the two pair shields is arranged between the wires. The shielding element has, in particular, individual wires which run next to one another. Contact can be made with the pair shield in a plug region in a simple manner by way of the shielding element. ## Claims ### Claim 1 A data cable, comprising: two wire pairs each including two wires; a pair shielding surrounding each of said two wire pairs; a planar shielding element disposed between said wire pairs and not encompassing said wire pairs, said planar shielding element making contact with each said pair shielding; and said planar shielding element is formed of a plurality of single individual wires extending adjacent to one another, said individual wires are a splayed-out stranded conductor. ### Claim 2 (depends on 1) The data cable according to claim 1, wherein said planar shielding element comprises a shielding foil. ### Claim 3 (depends on 2) The data cable according to claim 2, wherein said shielding foil comprises a ferro-magnetic material. ### Claim 4 (depends on 2) The data cable according to claim 2, wherein said shielding foil is a nickel foil or a coated carrier foil provided with a layer of powder particles. ### Claim 5 (depends on 1) The data cable according to claim 1, wherein said two wire pairs together with said shielding element form a stranded bundle. ### Claim 6 (depends on 1) The data cable according to claim 1, wherein said wire pairs contain wires that are not twisted wires. ### Claim 7 (depends on 1) The data cable according to claim 1, wherein said pair shielding is formed of a longitudinally extending pair foil. ### Claim 8 (depends on 1) The data cable according to claim 1, wherein each respective wire pair is a one piece construction with said two wires surrounded by a common wire insulation. ### Claim 9 (depends on 1) A method of transmitting signals, the method comprising: providing a data cable according to claim 1; and transmitting signals in the form of a differential data signal in a respective wire pair. ### Claim 10 (depends on 9) The method according to claim 9, which comprises transmitting the signals at a data rate greater than one gigahertz. ### Claim 11 (depends on 10) The method according to claim 10, which comprises transmitting the signals at a data rate greater than 5 GHz. ### Claim 12 A method for producing a data cable, the method comprising: providing two shielded wire pairs each having two wire pairs and a respective pair shielding; inserting a planar shielding element that does not surround the wire pairs between the two shielded wire pairs; and forming the data cable in a continuous process, and wherein the planar shielding element comprises a stranded conductor that is splayed-out and extends parallel with the wire pairs. ### Claim 13 (depends on 1, 12) The method according to claim 12, which comprises forming the data cable according to claim 1. ### Claim 14 (depends on 12) The method according to claim 12, which comprises forming the data cable in a continuous process, and wherein the planar shielding element is a shielding foil that extends parallel with the wire pairs. ### Claim 15 (depends on 12) The method according to claim 12, which comprises the respective pair shielding forming a longitudinally extending pair foil. ### Claim 16 (depends on 12) The method according to claim 12, where the data cable is provided exactly two wire pairs. ### Claim 17 (depends on 12) The method according to claim 12, which comprises each wire pair defining a longitudinal side, the two longitudinal sides facing each other and the planar shielding element being disposed between the two longitudinal sides. ### Claim 18 (depends on 12) The method according to claim 12, which comprises the two wire pairs together with the planar shielding element forming a stranded bundle.
