The nature of the Ge(2) center and ESR hyperfine structure with a splitting of 11. 9 mT, observed in germanium-doped silica fibers, is studied experimentally. It is considered that the Ge(2) center has a structure of -O-Ge equals O and that the 11. 9 mT hyperfine structure is due to a structure of H-Ge equals O. The former is a precursor of the latter, i. e. , the latter is yielded through chemical reaction of the former with hydrogen molecules.
