Abstract

Coherent optical signals transmitted through a single-mode fiber are highly sensitive to the refractive index changes caused by the fiber axis distortions, stresses and strains. Analysis of the the fiber axis distortions are most conveniently made by periodic perturbations of the fiber axis. Periodic perturbations may enhance periodic birefrengence, thereby, cause an optical signal phase delay[1,2]. Also, it may act as a dispersive filter[3], thus limiting the performances of a high speed optical communication system. Temperature affects the fiber coating, therefore, result in additional phase delay above which is already introduced in the fiber by the cabling process. It also affects the polarization state of the signal transmitted through the fiber.
