The aim of the research was to examine the formation and destruction of the hydroxyl in optical fibers by comparing the ambient atmosphere, air, and nitrogen during thermal treatment from room temperature up to 1100 °C. It has been shown that during the heat treatment, molecular hydrogen dissolved in the fiber plays no role in the formation of OH while under UV irradiation the formation is dependent on the presence of dissolved hydrogen. The heat treatment preferentially leads to the formation of Si-OH, while during irradiation it assists the formation of both Ge-OH and Si-OH. © 2017 Sumy State University.
