    Abstract: A method of manufacturing an optical fibre, comprises: (i) forming a preform (10) for drawing into the fibre, the preform (10) comprising a bundle of elongate elements, (20,50) arranged to form a first region that becomes a cladding region of the fibre and a second region that becomes a core region of the fibre; (ii) drawing the preform (10) into the fibre. The bundle of elongate elements (20,50) comprises a plurality of elongate elements (20) of a lower purity dielectric material and at least one elongate element (50) of a higher purity dielectric material. The first region comprises a plurality of the lower purity elements (20) and the second region comprises the higher purity element (50).
