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.

Telecommunications cable and method of making same

A method is disclosed for forming strands into twisted strand units having a twist direction that reverses from section to section wherein the strands are advanced side-by-side successively through first and second mutually spaced twister heads. The strands are formed into twisted strand units by the steps of operating the twister heads simultaneously by revolving the twister heads in a common rotary direction about the strands at substantially the same speed of head revolution thereby causing a first progression of twists of one lay direction to pass from the first twister head towards the second twister head, and a second progression of twists of opposite direction lay to emanate from the second twister head. Twisting operations by the first and second twister heads are simultaneously terminated as the leading end of the first progression of twists reaches the second twister head and a trailing end of the second progressing of twists emanating therefore. Twisting operations of the first and second twister heads are then suspended until a trailing end of the first progression of twists reaches the second twister head whereupon the foregoing steps are repeated.
