Chalcogenide hollow fibers were made from As-Se, As-Se-Te or Ge-Sb-Se cylindrical raw material. Theoretical investigation had shown that by using metallic cladding, losses due to bendings could be reduced. The optimum conditions for minimum loss were calculated for the ratio between TE and TM modes. Experimentally, fibers were drawn with an attenuation of 8 dB/m. It was shown that by using plastic for cladding, fibers with less fragility and high elasticity were achieved.
