Abstract: The subject of the invention is a data communications cable, characterized in that it comprises: a plurality of groups (1,2,3,4) of four pairs of isolated conductors, the four pairs of isolated conductors being assembled in a helical fashion following a group assembly pitch, each pair being twisted in a helical fashion and surrounded by an electrical shield (9,10), the plurality of groups (1,2,3,4) being assembled in a helical fashion following a final assembly pitch, an external sheath (8) surrounding the plurality of groups (1,2,3,4), the final assembly pitch being variable along the cable.
