Abstract
A cable is provided containing one or more polymeric elements for reduction of crosstalk. The cable includes a plurality of unshielded twisted pairs, each of which is an insulated conductor pair twisted around one another, each having a different lay length. A jacket encloses the plurality of unshielded twisted pairs, where an unshielded twisted pair, has the longest lay length among the plurality of unshielded twisted pairs is positioned within the center of the jacket such that an axis of the twisted pairs that has the longest lay length substantially coincides with the central longitudinal axis of the cable. A plurality of bumper elements are disposed within the jacket in the interstices between said plurality of unshielded twisted pairs, where the bumper elements are profiled polymer structures.
