Abstract

We compared the degradation of two kinds of 1550nm single-mode optical fibers following the irradiation by gamma ray (⁶⁰Co). Over a total dose of 9.06×10⁴ rad, the absorption coefficient increased while the rates were different between samples. The influence of ionizing radiation is theoretically analyzed. In room temperature annealing experiment, the absorption coefficient of Corning sample was recovered visibly, but Alcatel sample continues to deteriorate. It is suggested that different producing technology and doping are clearly influence the generation and recombination process of color center.
