METHOD AND APPARATUS FOR PROVIDING A HYDROGEN DIFFUSION BARRIER FOR FIBER OPTIC CABLES USED IN HOSTILE ENVIRONMENTS

摘要

A fiber optic conduit (100) for use in a hostile environment includes an axial tube (102) . The axial tube comprises a corrosion resistant material and is operable to receive one or more optical fibers . The fiber optic conduit further includes a hydrogen barrier shell (105) that is disposed in contact with the axial tube. The hydrogen barrier shell comprises a material that is capable of reducing hydrogen permeation through the fiber optic conduit and has a thickness of at least approximately one-thousandth of an inch.
