Polymeric coatings are the most important strength reliability factor of fiber optics. Diverse accelerated aging processes have been used in the last years with the objective to estimate the lifetime of fibers in real field situations. Because the humidity present at the glass- polymer interface determines the strength, a dry technique in fiber optics is used to understand the properties of coating permeability after aging process. Dry technique parameters can be connected with the strength evolution after months in hot water aging. To compare the efficiency of several coatings under this technique different fibers from different manufacturers were used. The strength measurements were made using the Two-Point Bending apparatus.
