New zirconium-free fluoride glasses are investigated for I.R. optical fibers operating up to 5-5.5 um. A five-component glass having the composition in molar percent fluoride Ba30In30Zn20Y10Th10 has been optimized for rods and preforms preparation. FC1 substitution as well as Na addition allow small variations in the refractive index. Two attempts on rods fibering were positive and demonstrated the possibility of obtaining BIZYT optical fibers without significant crystallization. Purification of indium and Yb based materials has been undertaken. Keywords Fluoride glasses, Indium-based, Zirconium, Optical fibers, Viscosity, Purification.
