Abstract

The experimental study of attenuation distribution changes of optical fiber in cable due cyclic temperature variations is represented in paper. It was observed that attenuation coefficient changes due temperature effect varies in irregular manner, that can be caused by redistribution of fiber curvature along cable. The fiber segments corresponding to the outer cable coils on the drum are most affected by temperature cycling, that can be due high thermal inertia of cable drum. The length of fiber segment with noticeable attenuation rising is approximately 500 m. The irregular local attenuation changes demonstrate the optical fiber curvature redistribution in cable due cyclic temperature variation and also can be used for estimation of variation of mechanical stresses.
