For solving the problems about Ge system chalcogenide glass fiber′s relatively high loss, etc, high-purity Ge₂₈Sb₁₂Se₆₀ glass was prepared by chemical and physical methods of purification. The absorptions caused by C, H, O impurities were obviously reduced in IR band. Ge₂₈Sb₁₂Se₅₈S₂ chalcogenide glass tube with precision wall and fine optical properties was prepared by means of tube-rotating technique. Fibers with core-cladding structure were drawn by rod-in-tube method. The diameter of the fiber is 50±1.5 μm and the bending test showed the diameter of the circle is 5 mm. The fiber loss is 2.2 dB/m (except those at 2.87 and 4.5 μm).
