Method of manufacturing a communication cable.

摘要

A cable comprises a central electrically insulating composite string, including a relatively hard strength member filament (8) with a relatively soft layer (9) thereon. Four, in the case of a quad, electrical or optical conductors (10) are at least partially embedded in the softer layer (9) and may abut the filament (9). A polyethylene sheath (11) is extruded over the string. The quad may be made by pressing the conductors against the outer periphery of the string whereby to deform it without heating it, and may involve the use of a die arrangement (Figs. 3 and 4) which ensures the desired spacing and configuration of the conductors relative to one another, necessary for high quality quads of electrical conductors in order to have low crosstalk, is obtained. The cable construction, which facilitates miniature quad manufacture, is such that cable can be manufactured with a minimum of process stages at high throughput speeds.
