  • Patent number: 8835765
    Abstract: A cable is provided with a first twisted pair of insulated conductors having a first lay length and a first insulation resulting in a first signal propagation rate and a second twisted pair of insulated conductors having a second lay length and a second insulation resulting in a second signal propagation rate. The second signal propagation rate is faster than the first signal propagation rate resulting a first amount of signal skew between signals travelling through the first twisted pair and the second twisted pair. A jacket covers the pairs. Titanium dioxide is added to the insulation of the conductors of the second twisted pair so that the dielectric constant of the insulation of the conductors of the second twisted pair is raised, lowering the second signal propagation rate, resulting in a second amount of signal skew which is less than the first amount of signal skew.
