Abstract

During maintenance of fiber optical communication lines the cyclic seasonal temperature variations can cause movement of optical fibers in loose tubes and redistribution of curvature. This is especially true for aerial suspended optical cables there significant “pushing out” of fiber from tubes in optical closures can be observed after years. In previous papers two methods for estimation of optical fiber curvature distribution based on reflectometric measurement on two wavelength and using polarization reflectometry were proposed. The results of estimation of optical fiber curvature distribution in all-dielectric self-supporting cable during cyclic temperature variation in climatic chamber are represented in paper.
