Abstract
A breathable downhole fiber optic cable is provided having an outer protective tube; a fiber optic tube having a plurality of optical fibers contained therein; at least one annulus disposed between the outer protective tube and the fiber optic tube; and at least one path, extending through the length of the fiber optic cable, which provides a channel for a purge gas to flow for removing a second gas, such as hydrogen, from the fiber optic cable.
