The optical fiber cable has a firm structure consisted of silica, steel, strings and plastics so that, is rarely recycled. Recently, plastics and steel of the cable have been reusing by means of the exclusive stripping machine, but it is not easy to recover the high purity silica. The hydrothermal pyrolysis characteristics of the optical fiber coating to reuse the silica are determined in this paper. The major controlling factors such as, temperature and pressure in the reactor, through the pyrolysis are experimentally clarified. The overall decomposition rate is also described in a modified Arrhenius equation.
