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 shell is substantially free from relying on the inner axial tube for mechanical integrity. |
