Abstract: Attenuation spectra of single mode fibers, subjected to periodic spatial deformations, have been investigated. The transmission spectra of the deformed single mode fibers show attenuation bands. These bands are a function of the period of the microbends, fiber radii, and cutoff wavelengths of the fibers. Mathematical relations have been developed to predict the location of the attenuation bands in the wavelength domain for specific microbending periods. Several standard single mode fibers were characterized for an increasing series of spatial deformation periods. Characteristic curves are plotted indicating the variation of parameters of the transmission spectra with change in the number and amplitude of the spatial deformation periods. Sensing applications utilizing the attenuation bands at specific spatial periods are presented and a multiplexed system is demonstrated. !10
