Abstract

A fiber optic cable system wherein one or more elongate metal strips extend parallel to each other in a longitudinal direction and at least one fiber optic cable is disposed adjacent to each of the one or more elongate metal strips. The at least one fiber optic cable also extends along the longitudinal direction. The one or more elongate metal strips and the at least one fiber optic cable are together encapsulated in an encapsulation, to form an encapsulated fiber optic cable extending in the same longitudinal direction.

First claim

What is claimed is:

1 . A fiber optic cable system comprising:
one or more elongate metal strips extending in a longitudinal direction; at least one fiber optic cable disposed adjacent to each of the one or more elongate metal strips and extending along said longitudinal direction and parallel to each of the one or more elongate metal strips; wherein the one or more elongate metal strips and the at least one fiber optic cable are together encapsulated in an encapsulation, to form an encapsulated fiber optic cable extending in said longitudinal direction.

2 . The fiber optic cable system of claim 1 , wherein seen in a cross section perpendicular to the longitudinal direction the one or more elongate metal strips and the at least one fiber optic cable are fully surrounded by the encapsulation.

3 . The fiber optic cable system of claim 2 , wherein seen in said cross section the encapsulation comprises a circular concave inside contour section and a circular convex outside contour section wherein the one or more elongate metal strips and the at least one fiber optic cable are positioned between the circular concave inside contour section and the circular convex outside contour section.

4 . The fiber optic cable system of claim 3 , mounted on a tubular element, the tubular element comprising a cylindrical wall about a central axis that is parallel to the longitudinal direction, wherein the cylindrical wall seen in cross section has a circular circumference having a convex outward directed wall surface; wherein the circular concave inside contour section has a radius of curvature that conforms to the convex outward directed wall surface.

5 . The fiber optic cable system of claim 1 , wherein the one or more elongate metal strips are each made out of a massive volume of metal and each have a four-sided cross section.

6 . The fiber optic cable system of claim 1 , wherein the at least one fiber optic cable comprises a first length of hydraulic tubing that is provided within the encapsulation and extends in the longitudinal direction.

7 . The fiber optic cable system of claim 6 , further comprising a second length of hydraulic tubing within the encapsulation, extending parallel to the first length of hydraulic tubing.

8 . The fiber optic cable system of claim 7 , further comprising a hydraulic tubing U-turn piece, configured at a distal end of the encapsulated fiber optic cable to create a pressure containing fluid connection between the first length of hydraulic tubing and the second length of hydraulic tubing.

9 . The fiber optic cable system of claim 6 , wherein the first length of hydraulic tubing is a capillary line.

10 . The fiber optic cable system of claim 1 , wherein the encapsulation is made of a thermoplastic material.

11 . The fiber optic cable system of claim 1 , wherein said one or more elongate metal strips comprise at least two elongate metal strips extending parallel to each other.

12 . The fiber optic cable system of claim 11 , wherein the at least one fiber optic cable is disposed between at least two of the one or more elongate metal strips.

13 . The fiber optic cable system of claim 1 , wherein the encapsulated fiber optic cable is spoolable around a spool drum.
