ABSTRACT:
The invention relates to a method and an arrangement for applying a coating on an end of an optical fiber by dipping said end into a unsolidified coating liquid. In a first sequence, the fiber end is moved towards the surface (18) of the liquid by a gripping means (11). The distance between the end face (26) of the fiber and the surface of the liquid is measured continuously by measuring means including a vision camera (23). The measured actual distance value is compared with a preset distance value and the first moving sequence is ended when the actual distance value is equal to the preset value. In a second sequence, the fiber end is dipped a predetermined depth in the liquid.
