Abstract
An optical communication cable is provided having a cable body with an inner surface defining a passage within the cable body and a plurality of core elements within the passage. A film surrounds the plurality of core elements, wherein the film directs a radial force inward onto the plurality of core elements to restrain and hold the plurality of core elements in place.
Claims14
An optical fiber cable, comprising:
- a plurality of optical fibers;
- a polymeric film surrounding the plurality of optical fibers and extending longitudinally along a length of the optical fiber cable, the polymeric film being contiguous in both a circumferential and an axial direction, and wherein a thickness of the polymeric film is less than 100 micrometers;
- a rip cord, the polymeric film further surrounding the rip cord;
- and
- a cable jacket having an interior cavity, the plurality of optical fibers and the polymeric film being disposed within the interior cavity, wherein the polymeric film is at least partially bonded to the cable jacket such that when the cable jacket is opened the polymeric film is also opened.

An optical fiber cable, comprising:
- a plurality of core elements, the core elements comprising an optical fiber;
- a polymeric film surrounding the core elements and extending longitudinally along a length of the optical fiber cable, the polymeric film being contiguous in both a circumferential and an axial direction;
- and
- a cable jacket formed from a first polymer material, the cable jacket comprising a co-extruded discontinuity that is formed from a second polymer material that is dissimilar to the first polymer material, the cable jacket bonded to the polymeric film such that when the cable jacket is opened by way of the co-extruded discontinuity, the polymeric film is also opened;
- wherein the optical fiber is a first optical fiber, the core elements further comprising:
- a second optical fiber;
- a first polymeric element surrounding the first optical fiber;
- and
- a second polymeric element surrounding the second optical fiber, wherein the first polymeric element and the second polymeric element are stranded about one another, and wherein the polymeric film surrounds the first and second polymeric elements and maintains the first and second polymeric elements in their stranded state;
- and
- wherein an average static friction force for a 200 millimeter section of the stranded first and second polymeric elements is at least 20 N.
