N2 - Recently, optical absorption was found at 1. 52 mu m, influencing the transparency at 1. 55 mu m where single-mode fibers are operated (M. Ogai et al. , 1986). The cause of this absorption is discussed. Five kinds of pure-silica silicone-clad fiber were used. Hydrogen treatment, gamma irradiation, and electron spin resonance measurements were carried out. The results indicate that the 1. 52- mu m absorption is caused by hydrogen molecules which form a hydrogen bond with peroxy radicals.
