ABSTRACT:
A cable, and process for manufacture thereof, containing optical transmission elements. The cable having the following characteristics: a central element stretching in the direction of the cable longitudinal axis, where the central element has at least one slot open to the outside and where the slot runs on the outside of the central element in a helix or screw-like manner, with periodically changing rotation direction; several optical fiber ribbons arranged inside the slot in a stack, situated one above the other, where an additional equal lay stranding is applied to the SZ-stranding imposed by the slot path; and a single or multi-layer jacket surrounds the central element.
