Optical fibres made from heavy metal oxide glasses doped by Dy3+ ions with the numerical aperture 0,4 - 0,9 are presented. Heavy metal oxide glasses in the system PbO-Ga2O3-Bi2O3-CdO doped by 1500 ppm Dy3+ ions were used. The method of their preparation and physical properties as well the results of luminescence investigations of Dy3+ ions embedded in glass hosts are reported. Double-crucible drawing technique was applied to obtain optical fibre doped by Dy3+ ions. Core and cladding glasses have been obtained by modification the base glass with small amounts of cadmium and gallium. In such a way these glasses possessed the same technological parameters which can be controlled in a wide range.
