Abstract
The long-term performance of optical fibers strongly depends on the mechanical properties of fiber coatings. A dynamic mechanical analysis technique, commonly used for polymeric materials, was adapted to optical fibers for direct measurements of storage modules (E')/loss tangent (tan (delta) ) - temperature profiles of coatings. This technique involved testing a parallel array of optical fibers in single cantilever bending. The measured fiber modulus profiles showed only a 50% drop through a glass transition region that was centered at about 30 degree(s)C, intermediate between the coating transitions measured on free films in tension. The fiber modulus profiles calculated from individual coating profiles are in agreement with the measured profiles. The dynamic mechanical analysis technique demonstrated in this report allows one to measure coating properties directly on fibers for failure analysis and investigations of aging effects.
