Telecommunications cable and method of making same
First Claim
1. A telecommunications cable comprised of more than five S-Z twisted wire pairs having their twist reversals longitudinally staggered in a repetitive sequence of 1 to N, where N is an integer, longitudinally spaced positions, and with said wires bundled together with any adjacent wire pairs having their twist reversals non-overlapped and staggered by no more than N/2 positions to limit S to Z coupling.

Abstract
A telecommunication cable, and method of making same, is disclosed comprised of more than five S-Z twisted wire pairs having their twist reversals longitudinally staggered in a repetitive sequence of 1 to N longitudinally spaced positions. The wire pairs are bundled with any adjacent pairs having their twist reversals non-overlapped and staggered by no more than N/2 positions which limits S to Z coupling.

4. A method of manufacturing a telecommunications cable comprising the steps of:
-
forming more than five S-Z twisted wire pairs; grouping the wire pairs with their twist reversal sections longitudinally staggered in a repetitive sequence of 1 to N positions, where N is an integer; and stranding the wire pairs into a unit with the pairs organized such that adjacent wire pairs have their twist reversals non-overlapping and staggered by no more than N/2 positions. - View Dependent Claims (5)

- 6. A method of stranding a group of more than five S-Z twisted wire pairs having their twist reversals longitudinally staggered in a repetitive sequence of 1 to N positions, where N is an integer, into a telecommunications cable characterized by low near end crosstalk, and with the method comprising the steps of advancing the more than five pairs through holes of a faceplate selected such that adjacent wire pairs have their twist reversals non-overlapped and staggered by no more than N/2 positions.
