The effect of optical signal intensity at the wavelength of system operation (0.85 μm) on the recovery of the radiation-induced attenuation in optical fiber waveguides following exposure to a 3700-rad dose of ionizing radiation has been investigated. Photobleaching has been observed in both pure and doped silica core fibers, although the effect is more pronounced in the former.
