Fiber optic strain locking arrangement and method of strain locking a cable assembly to tubing

摘要

A fiber optic strain locking arrangement includes a cable assembly having an outer radial surface, an optical fiber strain transmissively coupled to the outer radial surface, and tubing disposed at the outer radial surface. The tubing is strain locked to the outer radial surface through at least one of interference fit with granules at least partially embedded into at least one of the tubing and the outer radial surface and adhesive bonding to both the tubing and the outer radial surface.

1. A fiber optic strain locking arrangement comprising:
a cable assembly having an outer radial surface; an optical fiber being strain transmissively coupled to the outer radial surface; a tubing disposed at the outer radial surface and being strain locked to the outer radial surface through an interference fit; and a plurality of particles arranged between and at least partially embedded into, at least one of the tubing and the outer radial surface of the cable assembly, the plurality of particles facilitating, at least in part, the interference fit and having a hardness that is greater than a hardness of the cable assembly and the tubing.
