Zusammenfassung:An optical cable has optical transmission elements stranded about a central reinforcing member. The optical transmission elements are alternatively stranded in a first and second direction of rotation. A sheath surrounds the optical transmission elements, and markings are applied to the sheath to indicate switchback locations in the cable. The markings are applied to the sheath, which is separate from the optical transmission elements. Therefore, the markings need not be applied directly to the transmission elements, so the same control signal can be used to switch the direction of stranding and to apply the marking.
