UTP cable
A cable having a plurality of unshielded twisted pairs, each of which has a different lay length. A jacket encloses the plurality of unshielded twisted pairs, where the unshielded twisted pair with the longest lay length among the plurality of unshielded twisted pairs is positioned within the center of the jacket, substantially along the central longitudinal axis of the cable.
1. A cable for reducing 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; and
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.
2. The cable as claimed in claim 1 , wherein said unshielded twisted pairs are twisted pairs of copper wire.
3. The cable as claimed in claim 2 , wherein said twisted pairs are wrapped in foil.
4. The cable as claimed in claim 1 , wherein said cable maintains four unshielded twisted pairs, each of different lay lengths, the longest lay length of said four twisted pairs, being said centrally located unshielded twisted pair.
5. The cable as claimed in claim 4 , wherein the three non-longest lay length unshielded twisted pairs are located away from the center of said cable along an inside diameter of said jacket, disposed substantially 120 degrees apart from one another.
6. The cable as claimed in 5 , wherein said cable further comprises three bumper elements disposed between said non-longest lay length unshielded twisted pairs.
7. The cable as claimed in claim 5 , wherein said unshielded twisted pair having the longest lay length and being centrally located maintains an additional jacket.
8. The cable as claimed in claim 7 , wherein said unshielded twisted pair having the longest lay length and being centrally located is shielded.
9. The cable as claimed in 7 , wherein said additional jacket around said unshielded twisted pair having the longest lay length and being centrally located further comprises three radially extending branches.
10. The cable as claimed in claim 9 , wherein each of said radially extending branch is disposed between two of said three non-longest lay length unshielded twisted pairs.
11. The cable as claimed in claim 10 , wherein said jacket has alternating grooves and ridges.
12. The cable as claimed in claim 1 , wherein said jacket has alternating grooves and ridges.
