Abstract
An optical fiber cable comprising a layer of polymer coating containing a zeolite. The zeolite in the polymer coating acts as a desiccant and reduces the relative humidity at the innermost region of the cable. As a result of the reduced relative humidity inside the cable, the optical fiber is protected from delamination.
