Abstract

Fiber to the home networks plays a substantial role in helping operators to satisfy the increasing bandwidth demands of their subscribers. The dissemination of these networks brings new challenges, mainly in terms of the reliability of the optical fibers, especially when deployed in aggressive environments. In this work, we study the aging behavior of optical fibers in the presence of sodium chloride (NaCl) solutions, which can be a good indicator for the worst-case scenario of fiber deployed in seashore areas. In this perspective, the tensile stress behavior of the aged fibers was analyzed, and its lifetime was estimated, indicating an accentuated decrease in the lifetime, with the increase of the aging period, from the typically predicted 40 years down to near ~2 years.
