We report our recent progress on fabricating dehydrated tellurite glass fibers. Low OH content (1 ppm in wt.) has been achieved in a new halogen-​contg. lead tellurite glass fiber. Low OH-​induced attenuation of 10 dB​/m has been confirmed in the range of 3-​4 μm using three measurement methods. This shows the dehydrated halo-​tellurite glass fiber is a promising candidate for nonlinear applications in a 2-​5 μm region.
