The As40S60 core and As39S61 inner and outer cladding glasses were fabricated with the dynamic distillation purification process and melt-quenching method. The cladding tube was prepared by a computerized numerical control precision drilling machine, and then the fiber with the cladding and core diameter of 124 μm and 5 µm was produced by the combination of the secondary tube in rod method. The refractive index of core and cladding, cross-section dimensions, loss and bending loss of the fiber was measured and analyzed. The results show that the NA of the fiber is less than 0.425 in the wavelength range of 2.5-10.0 µm and its concentricity between core and cladding is good. The fiber has the minimum loss of 1.7 dB/m at 1 550 nm, and single-mode mode in the wavelength range of >2.5 µm. The fiber transmission losses increase sharply when the bending radius reduces to 20 mm.
