Abstract
The present invention is directed to a method and apparatus for improved long-term signal attenuation performance of fiber optic and/or fiber interface components. The improved long-term signal attenuation performance is achieved by introducing an additive such as deuterium into materials used in manufacturing the fiber optic cable. The fiber optic cable casing structure may then act as a reaction chamber so that the additive will react with the optical fibers and occupy defect site locations in the optical fibers. With the additive occupying defect sites in the optical fibers, it mitigates the presence of hydrogen into those same defect sites.
