Abstract:
    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 to be coloured are drawn simultaneously through the colouring tools and further simultaneously through the quartz tube of the UV lamp common to the fibres to be coloured.
