ABSTRACT:
A telecommunication cable comprises a plurality of conductor units bundled together, each conductor unit occupying a prescribed position in the cross-section of the cable and each conductor unit including at least four conductor pairs. The cable includes a plurality of lengthwise adjacent continuously connected sections, the conductor pairs of the conductor units being systematically interchanged in position relative to other conductor pairs of its respective conductor unit at each of said adjacent sections, and the conductor pairs being further systematically interchanged between conductor units at selected ones of the adjacent sections, so that both the grouping of the conductor pairs and the positions of the conductor units are systematically interchanged along the length of the cable. This systematic interchanging decreases the length over which any two conductor pairs are immediately adjacent each other and thereby reduces the cross-talk among the conductor pairs of the cable. Preferably, a given conductor pair of a conductor unit is taken as the base and the other conductor pairs are wound therearound.
