1. A fiber sensor package comprising:
- an interconnection between a first optical fiber and a second optical fiber disposed within a tubing comprising one or more noble metals and an aperture on the tubing at the vicinity of the interconnection, wherein the first and second optical fibers are at least partially disposed within the tubing; and
a bonding material disposed through the aperture and within the tubing at least partially around the circumferential surfaces of the first fiber and the second fiber at the interconnection and in the vicinity of the interconnection, bonding in place the first fiber and the second fiber such that fibers on each side of the bonding material can freely move towards opposite directions as a result of thermal expansion,wherein the first optical fiber comprises at least one fiber Bragg grating.

Abstract
A fiber sensor package is disclosed. The fiber sensor package includes an interconnection between a first optical fiber and a second optical fiber within a tubing such that the first and second optical fibers are at least partially disposed within that tubing. A bonding material is disposed across an edge of the interconnection around at least a part of the circumferential surfaces of the first and second fibers, holds rigid the interconnection of the first and second optical fibers. The methods of preparing the package, and the examples of systems benefiting from the fiber sensor package of this invention are also described.

15. A method of forming a sensing cable package comprising:
-
contacting a first optical fiber and a second optical fiber to form an interconnection; providing a tubing with an aperture at the vicinity of the intersection and the tubing comprising one or more noble metals, wherein the tubing circumferentially surrounds at least a length of the first and second optical fibers and the interconnection; disposing a bonding material through the aperture into the tubing to span across at least part of the circumferential surfaces of the first and second fibers along the interconnection; and setting the bonding material to form a rigid interconnection of the first and second fibers such that fibers on each side of the bonding material can freely move towards opposite directions as a result of thermal expansion. - View Dependent Claims (16, 17, 18)
