Single-mode As–S glass fibers with a core diameter from 3 to 20 μm and a clad diameter of 125 μm are prepared by the double-crucible method. The cutoff wavelength of the fibers is 0.9–6 μm. The lowest transmission losses in the fibers at 2.2–2.3 μm are ∼100 dB/km, and their mean bending strength is 800–1000 MPa.
