Abstract
The primary coating (2) of an optical fibre element is reinstated over a fused joint between two silica fibre elements (3) by a casting process. The jointed silica fibre elements are arranged in a groove (8) of a mould (9, 10, 11) and liquid uncured primary coating material placed into the groove, the groove ends being blocked by the existing primary coatings (2) on the fibre elements (3). The coating material in the groove is cured by, for example, heating the mould. Secondary coating material (1) may be injection moulded using a two-part mould to reinstate the secondary coating over the cast primary coating.
