Abstract
A fiber optic cable for use in a downhole environment is disclosed. The fiber optic cable includes a tube having an interior region; an optical fiber disposed in the interior region of the tube; a gas in the interior region; and a gel in the interior region, wherein the gel is configured to reduce stress on the optical fiber in the presence of the gas at a temperature substantially near the flashpoint of the gel. One or more seals can be used to seal the gel and the inert gas in the interior region. In various aspects, the fiber optic cable can be used in a downhole environment.
