Abstract
An optical fiber cable contains a central strength member surrounded by a plurality of fiber-carrying guides traversing the length of the cable along reversing helical paths. A plurality of strength members are provided in lieu of selected symmetrically spaced guides. The strength members provide axial and torsional stability due to their reversing helical path. Periodic bandmarks are provided on each fiber for identification. An excessive length of fiber is provided in each guide to minimize fiber stress.
