Abstract

An opto-electrical cable may include an opto-electrical cable core and a polymer layer surrounding the opto-electrical cable core. The opto-electrical cable core may include a wire, one or more channels extending longitudinally along the wire, and one or more optical fibers extending within each channel. The opto-electrical cable may be made by a method that includes providing a wire having a channel, providing optical fibers within the channel to form an opto-electrical cable core, and applying a polymer layer around the opto-electrical cable core. A multi-component cable may include one or more electrical conductor cables and one or more opto-electrical cables arranged in a coax, triad, quad configuration, or hepta configuration. Deformable polymer may surround the opto-electrical cables and electrical conductor cables.

First claim

What is claimed is:

an opto-electrical cable core comprising a wire, one or more channels formed within the wire and extending along a longitudinal axis of the wire, and one or more optical fibers extending longitudinally within each channel, wherein the wire comprises a base wire and a cap wire, wherein one channel is formed within the base wire between two portions of a base wire mating face of the base wire and extends along the longitudinal axis the base wire, and wherein the cap wire comprises a tab mechanically coupled within the one channel of the base wire, enclosing the one channel; and
a polymer layer longitudinally and circumferentially surrounding the opto-electrical cable core.

2. The opto-electrical cable of claim 1 , wherein the wire comprises one or more channels formed within the wire about an outer circumference of the wire, and wherein each channel is formed between two portions of the outer wire circumference.

3. The opto-electrical cable of claim 2 , wherein the wire comprises a base formed along the outer wire circumference and extending longitudinally along the wire, and one channel formed between two portions of the outer wire circumference and extending along the longitudinal axis of the wire opposite the base.

4. The opto-electrical cable of claim 1 , wherein the wire has a C-shaped profile.

5. The opto-electrical cable of claim 1 , further comprising one or more completion layers, wherein the one or more completion layers comprise:
a layer of cladding longitudinally and circumferentially surrounding the polymer layer; or
a jacket layer longitudinally and circumferentially surrounding the polymer layer, wherein the jacket layer comprises wires encased within a polymer; or
a tube longitudinally and circumferentially surrounding the polymer layer, wherein the tube comprises two arcuate metal wires, and a second polymer layer surrounding the tube; or
a metallic tape longitudinally and circumferentially surrounding the polymer layer, wherein the metallic tape comprises a longitudinally crimped seam, and an additional layer of polymer longitudinally and circumferentially surrounding the metallic tape; or
a soft polymer layer longitudinally and circumferentially surrounding the polymer layer, a plurality of arch-profile wires longitudinally and circumferentially surrounding the soft polymer layer, wherein a portion of the soft polymer layer fills interstitial spaces between the arch-profile wires, and a layer of stranded wires encased within one or more additional layers of polymer longitudinally and circumferentially surrounding the plurality of arch-profile wires.

6. A multi-component cable comprising:
one or more electrical conductor cables;
one or more opto-electrical cables, wherein each opto-electrical cable comprises an opto-electrical cable core comprising a wire, one or more channels formed within the wire and extending along a longitudinal axis of the wire, and one or more optical fibers extending longitudinally within each channel, and a polymer layer longitudinally and circumferentially surrounding each opto-electrical cable core;
one or more layers of deformable polymer longitudinally and circumferentially surrounding the one or more opto-electrical cables and the one or more electrical conductor cables, wherein the one or more opto-electrical cables and the one or more electrical conductor cables are arranged within the one or more layers of deformable polymer in a coax configuration, a triad configuration, a quad configuration, or a hepta configuration;
a first jacketing layer longitudinally and circumferentially surrounding the one or more layers of deformable polymer, wherein the first jacketing layer comprises: a plurality of arch-profile wires longitudinally and circumferentially surrounding the one or more layers of deformable polymer, wherein a portion of the one or more layers of deformable polymer fills interstitial spaces between the arch-profile wires; or a layer of corrugated metallic tape longitudinally and circumferentially surrounding the one or more layers of deformable polymer, wherein the layer of corrugated metallic tape is at least partially embedded into the one or more layers of deformable polymer; or a layer of metallic cladding tape longitudinally and circumferentially surrounding the one or more layers of deformable polymer; or a hard polymeric layer longitudinally and circumferentially surrounding the one or more layers of deformable polymer; and
one or more layers of armor wires encased within one or more layers of reinforced polymer longitudinally and circumferentially surrounding the first jacketing layer.

7. The multi-component cable of claim 6 , wherein the one or more opto-electrical cables and the one or more electrical conductor cables are arranged within the one or more layers of deformable polymer in a hepta configuration.

8. An opto-electrical cable comprising:
an opto-electrical cable core comprising a wire, one or more channels formed within the wire and extending along a longitudinal axis of the wire, and one or more optical fibers extending longitudinally within each channel, wherein the wire comprises one channel formed within a central interior of the wire and extending along the longitudinal axis of the wire, wherein the one channel comprises an opening formed between two portions of an outer wire circumference of the wire, and wherein the opto-electrical cable further comprises: a filler encasing the one or more optical fibers within the one channel; and a plug mechanically coupled with or chemically bonded to the wire at the opening of the one channel, wherein the plug encloses the one channel; and
a polymer layer longitudinally and circumferentially surrounding the opto-electrical cable core.
