Abstract
We present results of measurements of fiber bend losses induced by periodic distortions in a single-mode and a multimode fiber having step and graded index profile. These bends are caused by soft and swellable materials with various moduli of Young. We found that the attenuation increases for longer periods of perturbations. The transition losses and pure bend losses have been calculated. Our experimental conditions show that the purebend loss is higher than the transition loss, i.e. the mode coupling mechanism of the loss is low in our experiments. These results may be used to choose suitable materials and construction for assembling a fiber optics sensor based in bend losses.
