ABSTRACT:
Fiber optic cables suitable for use in harsh environments such as down hole oil and gas well applications and methods for fabricating the same have been provided. In one embodiment, an optic cable suitable for down hole oil field applications comprises one or more optical fibers disposed in an inner tube and a corrosion resistant metal outer tube disposed over the inner tube, where the inner and outer tubes make intermittent contact. In another embodiment, an optic cable suitable for down hole oil field applications comprise one or more optical fibers disposed in a polymer tube having fins extending therefrom.
