摘要： The invention relates to an optical fibre ribbon (30; 40; 50; 60), comprising at least two optical fibres (11) extending in the longitudinal direction of the ribbon, the longitudinal axes of which fibres are substantially parallel with each other and which fibres are substantially in the same plane in the direction transverse to the fibre ribbon. In order to provide a fibre ribbon structure, which is as easy-manufactured as possible and capable of implementing easily different division ratios between the fibres when branching the fibre ribbon, the fibre ribbon structure has been weakened at least at one fibre by varying at least one coating layer (32, 33, 34a, 34b) of said fibre with respect to the corresponding layers of the other fibres. In one preferred embodiment, the weakening has been implemented by a structure in which the colour layer (34a; 34b) surrounding a fibre adjacent to a desired division surface (C) is thicker than the colour layer (34) surrounding the other fibres (11).

摘要： A method of producing an optical multi-fibre conductor element (11) by extruding (5) a secondary sheathing (6) loosely around a fibre bundle of several optical fibres (1); providing the fibres with a desired extra length (8) with respect to the secondary sheathing; and reeling the conductor element onto a receiving reel (12). In order to provide an extra length to compensate for differences occurring in the tension of the fibres and to avoid permanent variation in the length of the fibres in the secondary-sheathed fibre bundle, the fibres are spread (14, 15) side by side before the extrusion of the secondary sheathing, and passed side by side around an equalizer wheel (13), and further to the extruder while still positioned side by side. An apparatus for realizing the invention comprises means (14, 15) for spreading the fibres before the extruder (5); and an equalizer wheel (13) around which the fibres are arranged to be passed side by side.
