Abstract
A high power opto-electrical cable with multiple power and telemetry paths and a method for manufacturing the same includes at least one cable core element and at least one high-power conductor core element incased in a polymer material jacket layer. The cable core element has at least one longitudinally extending optical fiber surrounded by a pair of longitudinally extending arcuate metallic wall sections forming a tube and a polymer material jacket layer surrounding and incasing the wall sections, wherein the optical fiber transmits data and the wall sections transmit at least one of electrical power and data.

A method of making a cable, wherein the method comprises:
- providing a cable core, wherein providing a cable core comprises:
- extruding a polymer material about a metallic wire forming a central element;
- cabling two or more high-power conductor core elements and one or more copper tube cable core elements helically around the central element, wherein the central element deforms to fill interstitial spaces between the core elements, forming cabled core elements, wherein the one or more tube cable core elements comprise a first layer of copper halves surrounding at least one optical fiber, an inner jacket, a second pair of copper halves surrounding the inner jacket, and an outer jacket about the second pair of copper halves;
- extruding an additional polymer material about the cabled core elements and forming a circular profile, wherein the at least one optical fiber is packaged loosely into the first layer of copper halves;
- applying a first layer of polymer material about the cable core;
- applying a first layer of armor wires about the first layer of polymer material;
- applying a second layer of polymer material about the first layer of armor wirers;
- applying a second layer of armor wires about the second layer of polymer material;
- and
- applying an outer layer of fiber reinforced polymer material about the second layer of armor wires.
A cable comprising:
- a cable core wherein the cable core comprises:
- a polymer material about a metallic wire forming a central element;
- two or more high-power conductor core elements and one or more copper tube cable core elements helically cabled around the central element forming cabled core elements, wherein the central element deforms to fill interstitial spaces between the core elements, wherein the one or more copper tube cable core elements comprise a first layer of copper halves surrounding at least one optical fiber, an inner jacket, a second pair of copper halves surrounding the inner jacket, and an outer jacket about the second pair of copper halves;
- an additional polymer material extruded about the cabled core elements, forming a circular profile, wherein the at least one optical fiber is packaged loosely into the first layer of copper halves;
- a first layer of polymer material about the cable core;
- a first layer of armor wires about the first layer of polymer material;
- a second layer of polymer material about the first layer of armor wirers;
- a second layer of armor wires about the second layer of polymer material;
- and
- an outer layer of fiber reinforced polymer material about the second layer of armor wires.
