Abstract
An optical fiber cable having a minimum bend radius and comprising at least one U-shaped carrier helically stranded about a coaxial rod having a central axis and including in its lateral peripheral surface at least one groove, said groove containing at least one optical fiber element, is characterized in that the maximum compressive force on said U-shaped carrier caused by bending the cable to its minimum bend radius is less than the minimum such force which could cause said U-shaped carrier to buckle toward said groove. A cable with 16-fiber ribbons containing 250 .mu.m outer diameter (OD) fibers may contain up to 3200 optical fibers. The cable cross-section packing density may be 2.13 fibers/mm.sup.2.
