摘要：Ge-doped-silica core optical fibers are studied. One of the most important harm ful effects of radiation on optical fibers is that the radiation induced transm ission loss in optical fibers. A block diagram model of the radiation induced transmission loss at 850 nm is developed by using VisSim environment. The m odel results show the attenuation induced absorption in optical transmitted signal. Moreover they show also the post-irradiation recovery forecasting which occurs as a result of the recombination process that take place after radiation exposure. In addition this formulated treatment provides the ability of choice the operating wavelength that achieves m inimum attenuation along the optical fiber when used in radiation environm ents. The results are validated against published experimental work and showed good agreement.
