Abstract:
A high performance data cable comprising:a plurality of twisted pairs of insulated conductors; a generally cross-shaped core having arms with flanged ends extending sufficiently far around each twisted pair of insulated conductors to retain each twisted pair of insulated conductors in stable positions apart from each other, thereby controlling cross-talk between adjacent twisted pairs whose distance apart does not vary during cable installation and use; and a jacket generally surrounding the plurality of twisted pairs of insulated conductors and the core and held at a substantially constant distance away from each twisted pair of insulated conductors by the arms of the cross-shaped core, thereby controlling attenuation variation due to a loss tangent of the jacket; wherein two adjacent arms of the cross-shaped core define a substantially polygonal void in which one of the twisted pairs of insulated conductors is retained.
