Abstract

The recovery of radiation induced excess loss in optical fibers is dependent on the material composition and purity on the one hand and on environmental and test parameters on the other hand. We already described the general recovery characteristics and its dependence on the preform and fiber properties [1]. Here, we present our results on the effects of the following test parameters on the recovery rates: bremsstrahlung dose, electron dose, electron energy, light wavelength, light power and fiber temperature. Pure-silica-core op-tical fibers were irradiated with bremsstrahlung or electrons from a Febetron 705 and the recovery was measured in the time regime 10^-6s to 10⁴s. The experimentally determined de-pendencies should be helpful in developing a consistent theoretical understanding of the transient radiation effects in optical fibers.
