Long single-mode and multimode fluoride glass fibres with core-clad structure are fabricated for the first time by the double-crucible technique. 500 m-long single-mode fibre and 700 m-long multimode fibre are obtained using ZrF4-BaF2-NaF-LaF3-AlF3 core and ZrF4-BaF2-NaF-LaF3-AlF3-HfF4 clad glasses.
