Abstract
A cable includes a first twisted pair of insulated conductors having a first lay length and a second twisted pair of insulated conductors having a second lay length, where the second lay length is longer than the first lay length. At least one jacket covers the pairs. An additive 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 relative to the dielectric constant of the insulation of the conductors of the first twisted pair resulting in a reduced skew between the first and second twisted pairs.
