Infrared spectra of optical fiber cladding materials have been investigated by the irradiating treatment, and the quenching and annealing process with different temperature. The results show that, with the method of quenching firstly, the 1100 cm^-1 peak in the IR spectrum of cladding materials changes dramatically, which may attribute to the quenching process, corrected the fictive temperature and induced structural disorder. And then, the irradiation process induces defects. Finally annealing process can make the material become more stable, but the intensity and shape of 1100 cm^-1 peak no change remarkably. This result shows that annealing process repaired the structural disorder induced by quenching process and the defects induced by irradiated.
