Profile filler tubes in LAN cables

A cable containing one or more polymeric elements for reduction of crosstalk, said cable comprising:

• 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 enclosing said plurality of unshielded twisted pairs, wherein an unshielded twisted pair, having the longest lay length among said plurality of unshielded twisted pairs is positioned within the center of said jacket such that an axis of said twisted pair having the longest lay length substantially coincides with the central longitudinal axis of said cable and with said remaining unshielded twisted pairs positioned around said twisted pair with the longest lay length at the center;
• and
• a plurality of fin shaped bumper elements disposed within said jacket in the interstices between said plurality of unshielded twisted pairs, wherein said fin shaped bumper elements are polymer structures, having at least two fins radially extending from a center point, and having a diameter substantially the same size as a diameter of said unshielded twisted pairs, said fin shaped bumper elements having a helical twist of a lay length sufficient to prevent said remaining unshielded twisted pairs positioned around said twisted pair with the longest lay length at the center from contacting one another along the length of the cable.
