ABSTRACT:
A fiber optic cable for use in a hostile environment includes a fiber in metal core. The fiber in metal core includes one or more optical fibers that are disposed inwardly from an inner axial tube. The fiber optic cable also includes a hydrogen barrier shell that is disposed outwardly from the inner axial tube. The hydrogen barrier shell includes a material that is capable of reducing hydrogen permeation through the fiber optic cable. In this particular embodiment, the hydrogen barrier layer also includes a thickness of at least one-thousandth of an inch.
