Abstract:
We investigated the physical degradation effect of the optical fiber due to electron beam exposure and can be determined through the measurement of radiation induced attenuation that is proportional to the radiation dose. The optical fibers that were used in the study were single mode and multimode fiber types. Radiation induced attenuation in the optic fiber was measured before, during and after electron beam exposure and for two wavelength values specific to each type of optic fiber. The measurements show a dependence of the radiation induced attenuation to the radiation dose for a some types of fibers. The applied irradiation dose was different because some fibers required a much larger irradiation dose to reach saturation and others were not influenced at all.
