The invention relates to a method and an arrangement for colouring optical fibres, each fibre (1) being drawn through an upper nozzle (3) in a colouring tool (2) into a colour chamber (5), into which colorant is introduced, and further through a lower nozzle (4) out of the colour chamber (5). The coloured fibre is passed onward through a quartz tube (7) of a UV lamp (6) curing the colorant. To reduce costs and to increase the production rate, the colouring tools (2) are arranged close to each other in pairs in at lest two different planes, and the fibres (1) to be coloured are drawn simultaneously through the colouring tools (2) and further simultaneously through the quartz tube (7) of the UV lamp (6) common to the fibres to be coloured.
L'invention concerne une méthode et un appareil pour colorer des fibres optiques. Chaque fibre (1) passe à travers une buse supérieure (3) d'un outil de coloration (2) jusque dans une chambre de coloration (5), dans laquelle le colorant est introduit, puis à travers une buse inférieure (4) pour sortir de la chambre en question (5). La fibre colorée passe ensuite dans un tube de quartz (7) d'un émetteur ultraviolet (6) pour faire durcir le colorant. Afin de réduire les coûts et d'augmenter le taux de production, les outils de coloration (2) sont disposés par paires très près les uns des autres sur au moins deux plans différents. Les fibres (1) à colorer passent donc simultanément à travers les outils de coloration (2), puis à travers le tube de quartz (7) de l'émetteur ultraviolet (6) commun aux fibres à colorer.
