| dc.description.abstract | An experimental technique of macrobending losses for a single mode fiber (SMF) with different radius of curvature is presented. Macrobending losses for SMF are investigated experimentally, showing that a tight bent of fiber has a significant impact on the power loss. This experimental measurement suggests how this method is crucial to characterize macrobending at wavelength of interest even to calculate the power loss due to bending, to determine the spectral window at which the fiber can effectively operates, to predict the bend loss for a higher wavelength from the trend of shorter wavelengths. This thesis work also investigates the variation of the constants, CR and C , which depends on the waveguide dimension, with respect to shorter wavelengths using He-Ne laser and Mercury Vapor Lamp sources of light that emits different wavelengths in the visible and ultraviolet region of an optical spectrum using an optic beam launch method. Corresponding experimental tests are presented, which agree with the theoretical results that show, the bent fiber at different bend radii has a significant influence on the total loss of the fiber.
