US Patent:

54955467, Feb 27, 1996

Filed:

Apr 13, 1994

Appl. No.:

8/227251

Inventors:

Jack Bottoms - Roswell GA
Charles L. Carter - Alpharetta GA

International Classification:

G02B 644

US Classification:

385101

Abstract:

The present invention is directed toward an optic static wire assembly comprising a central core which has one or more helical channels in its periphery. One or more tubes containing a dielectric water-blocking compound and one or more optical fibers are positioned in the channels. The tubes are coated with a thermal insulation material, and then a heat reflective material. The optical fibers are randomly arranged within the tubes in such a way that tensile stresses on the cable are not transmitted to them. Finally, the assembly formed by the core and the tube or tubes is wrapped with a serving of metal wires. In one embodiment, the core and tubes may be wrapped with a tape layer before the outer metal wires are applied. Any interstices among the core, the tube or tubes, and tape may also be filled with another dielectric water-blocking compound.

International Classification:

G02R 644

US Classification:

385113

Abstract:

An all dielectric self-supporting fiber optic communication cable for use between spaced-apart support towers of an electrical power transmission network. A central core including at least one optical fiber is surrounded by a layer of non-conductive stranded strength members that are wound about the core. The core includes a plurality of pliable buffer tubes, each of which houses a bundle of optical fibers. The buffer tubes are helically wound about a cylindrical element in order to provide temperature performance by preventing the buffer tubes from experiencing thermally induced movement when exposed to varying temperatures. Each of the stranded strength members comprises a bundle of non-conducting filaments or fibers that are formed about a reinforcing element and encapsulated by individual polyethylene jackets. The reinforcing element reduces the tendency of the filaments to compress as the extruded jacket cures. The stranded strength members are helically wound about the central core.
