Abstract
The invention is directed to a multi-pair cable having an outer jacket and at least two pairs of twisted wire cables having different lay lengths and being disposed within the jacket. The wires of each twisted wire pair have a conductor surrounded by an insulating material, wherein the conductors of the respective twisted wire pairs have different strand twist lengths. The lay lengths of the twisted wire pairs are correlated with the strand twist length of the conductors of the individual twisted wire pairs so that the phase delay of the twisted wire pairs of the cable is matched to within an acceptable range for data transmission. Conversely, where the lay lengths of the twisted wire pairs is specified, the strand twist lengths of the respective conductors of the individual twisted wire pairs can be correlated with the lay lengths of the twisted wire pairs so that the phase delay of the twisted wire pairs of the cable is brought to within an acceptable range for the intended application.
