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:

1. A cable, comprising:
a base wire having a channel formed therein;
one or more optical fibers disposed within the channel;
a cap wire configured to encapsulate the one or more optical fibers within the channel;
wherein the base wire includes a mating channel having base wire mating surfaces, wherein the cap wire includes a mating tab having a mating surface, and wherein, when the cap wire is coupled to the base wire, the mating surface of the mating tab engages with the base wire mating surfaces.

2. The cable of claim 1 , wherein the base wire mating surfaces are a first set of base wire mating surfaces, wherein the mating channel includes a second set of base wire mating surfaces that are offset from the first set of base wire mating surfaces by respective intermediate surfaces.

3. The cable of claim 2 , wherein the cap wire includes mating protrusions extending from the mating tab and having additional mating surfaces, wherein, when the cap wire is coupled to the base wire, the mating surface of the mating tab engages with the first set of base wire mating surfaces and second mating surfaces of the mating protrusions engage with the second set of base wire mating surfaces.

4. The cable of claim 1 , wherein the base wire includes a mating groove having base wire mating chamfers extending from respective edges of the channel, wherein the cap wire includes an arch-profile geometry having inclined mating surfaces, and wherein, when the cap wire is coupled to the base wire, the inclined mating surfaces engage with the base wire mating chamfers.

5. The cable of claim 1 , wherein the base wire includes a receiving channel having curved mating surfaces extending from respective edges of the channel, wherein the cap wire includes a circular cross-sectional geometry, and wherein, when the cap wire is coupled to the base wire, an outer profile of the cap wire engages with the curved mating surfaces.

6. The cable of claim 5 , wherein the cap wire engages with the receiving channel via an interference fit.

7. The cable of claim 1 , wherein the one or more optical fibers are in contact with the base wire, the cap wire, or both, such that compressive forces applied to the base wire and/or the cap wire are transferred to the one or more optical fibers.

8. The cable of claim 1 , wherein the cap wire, when coupled to the base wire, forms a cable core of the cable, wherein the cable core is encompassed by one or more polymer jackets.

9. The cable of claim 8 , comprising one or more completion layers disposed about the one or more polymer jackets, wherein the one or more completion layers comprise metal cladding, helically cabled wires, arcuate metal wires, helically wrapped metallic tape, helically wrapped corrugated metallic tape, helically cabled arch-profile wires, or a combination thereof.

10. The cable of claim 1 , wherein the cap wire, when coupled to the base wire, forms a cable core of the cable, wherein a plurality of arch-profile wires are cabled helically about the cable core.

11. The cable of claim 1 , wherein the cable is configured to be positioned within a multi-component cable having a coax, triad, quad, or hepta configuration.
