Appl. No.:

10/420309

Luis M. Bocanegra - Alpharetta GA

International Classification:

G02B 644

US Classification:

385114

Abstract:

The specification describes an improved optical fiber ribbon cable. The cable design addresses the problem of wrinkles in the cable coating that occur on the interior bend radius on moderate bending of the cable. The wrinkles are much smaller than the bend radius, and are, relatively speaking, microbends. These may cause microbending losses in the fibers even where the bend radius is relatively large. The cable design of the invention has a combination of three important features. The cable cross section is round. The encasement for the optical fiber stack is relatively hard, and is deliberately made to adhere to the optical fiber stack. Consequently the encasement medium functions as an effective stress translating medium that deliberately translates stresses on the cable to the optical fibers. The optical fibers function as compressive strength members to retard longitudinal strain on the cables, and thereby reduce wrinkling of the encasement.

International Classification:

G02B006/44

US Classification:

385114

Abstract:

The specification describes an improved optical fiber cable wherein the cable cross section is round and contains a plurality of bundled optical fibers. The bundle may comprise randomly arranged optical fibers or optical fibers aligned in a ribbon configuration. The bundle is encased in a polymer encasement that couples mechanically to the optical fibers. In some embodiments the encasement is relatively hard, and is deliberately made to adhere to the optical fiber bundle. Consequently the encasement medium functions as an effective stress translating medium that deliberately translates stresses on the cable to the optical fibers. The cable construction of the invention is essentially void free, and provides a dry cable with water blocking capability.

US Classification:

385102, 106107

Abstract:

The specification describes an improved optical fiber cable wherein the cable cross section is round and contains a plurality of bundled optical fibers. The bundle may comprise randomly spaced fibers or fibers aligned in a ribbon configuration. The bundle is encased in a polymer encasement that couples mechanically to each optical fiber. Preferably, the fibers are spaced from the nearest neighbor to improve coupling. In some embodiments the encasement is relatively hard, and is deliberately made to adhere to the optical fiber bundle. Consequently the encasement medium functions as an effective stress translating medium that deliberately translates stresses on the cable to the optical fibers. The cable construction of the invention is essentially void free, and provides a dry cable with water blocking capability.

International Classification:

G02B 644

US Classification:

385102

Abstract:

A preferred embodiment of the cable of the present invention incorporates a core, an outer jacket surrounding the core, and a tape disposed between the core and the outer jacket. The tape includes a first layer and superabsorbent polymers (SAPs) which are applied to the first layer. Preferably, the first layer is formed of spun bonded non-woven polyester material, nylon spun bonded fabric, non-woven glass, polypropylene melt blown non-woven fabric, polyurethane spun bonded fabric, or TCF cellulose fabric, among others. Additionally, the SAPs preferably are provided with a moisture content of greater than approximately 2 percent, by weight, thereby improving the flame-retarding characteristics of the tape.
