    • The data cable (2) is used for high-speed data transmission at signal frequencies of > 10 GHz and comprises at least one core pair (4) which is surrounded by a film-like pair shield (6) which has an inner shielding film (14) and an outer shielding film (16) which are in electrical contact with one another, wherein the inner shielding film (14) is wound around the core pair (4). 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.
    • 用于在> 10GHz的信号频率的高速数据传输的数据电缆包括至少一个芯线对,其被具有内屏蔽膜和外屏蔽膜的膜形对屏蔽围绕,该屏蔽膜与一个 另一个并且其中内屏蔽膜缠绕在芯对上。 由于这种措施,避免了不期望的谐振效应,在先前的绕组对屏蔽中,不能用于相对较高的信号频率。 同时,在纵向折叠的屏蔽膜的情况下会发生不想要的共模信号。
