Abstract : New multicomponent Zr free fluoride glasses are investigated for I.R. optical fiber preparation. A rotational casting technique associated with the fabrication of a new dry glove box have been developed in order to prepare tube and then core-clad preform. The glass BIZYT based ion indium and barium essentially can be shaped as a tube without crystallization. Attempts for core-clad preform design indicate a tendency of crystallites formation at the core-clad interface. Contamination of the glass by transition metals and viscosity measurements are in a early stage of investigation. Keywords: Fluoride glasses; Optical fiber; Preform preparation; Rotational casting; Transition metal impurities; Viscosity.
