Abstract

A method for making a cable includes creating a curvature in a conduit; pumping one or more fibers into the conduit; and securing at least one of the one or more fibers to a shortest pathway within the conduit and cable.

Claims

1. A cable comprising:

a helically curved conduit; and

one or more optical fibers positioned immovably at inner surface of the conduit and disposed consistently at the shortest pathway through the conduit.

2. The cable as claimed in claim 1 wherein the fiber includes one or more fiber bragg gratings therein.

3. The cable as claimed in claim 1 wherein at least one of the one or more fibers is affixed to the conduit.

4. The cable as claimed in claim 3 wherein the cable further includes a hardenable material therein to affix the fiber.

5. The cable as claimed in claim 4 wherein the hardenable material is a material containing epoxy.

6. The cable as claimed in claim 4 wherein the hardenable material is thinned with a thinner.

7. The cable as claimed in claim 6 wherein the thinner is acetone.

8. The cable as claimed in claim 4 wherein hardenable material is configured as a coating on an inside surface of the conduit.

9. The cable as claimed in claim 8 wherein the coating defines an open passageway that is receptive to a communication fluid.

10. The cable as claimed in claim 8 wherein hardenable material is configured as a plurality of stacked coatings on the inside surface of the conduit.

11. The cable as claimed in claim 1 wherein the fiber is in a consistent position relative to a tubular about which the cable is disposed.
