A fiber optic conduit for use in a hostile environment includes a hydrogen barrier shell that is disposed outwardly from an inner axial tube. The hydrogen barrier shell comprises a material that is capable of reducing hydrogen permeation through the fiber optic conduit and a thickness of at least approximately one-thousandth of an inch. The inner axial tube is operable to receive one or more optical fibers. The conduit further includes an outer axial tube that is disposed outwardly from the hydrogen barrier shell and is operable to form a hydrostatic pressure boundary for the fiber optic conduit.
