Ge-As-Se-Te glass fiber having the core-cladding structure was prepared using a rod-in-tube method. Fibers more than 30 m in length were drawn from a crucible with a nozzle and coated with an UV curable polymer. The diameters of the core and clad were 300 and 420 μm, respectively. The transmission loss spectra of the fibers were measured by the cut-back method and 0.6 dB/m was attained at the wavelength of 8.5 μm.
