    摘要： For removal of the protective coating (51) of cables, in particular optical 12-fiber ribbons and other optical multifiber ribbons, a tool divided into several segments (53) is used. Each of the segments have a pair of blades (55) comprising opposed edges and they are displaceable in relation to each other only a predetermined distance. When the tool is applied to a cable and a force is applied to the end thereof in the longitudinal direction of the cable, the protective jacket will be removed in stages, but still in a single operation, so that first a short subsection at the end of the cable is pulled away through some distance and then a short subsection further away from the end of the cable, etc. The force required when using this method is relatively small and the protective jacket can therefore be removed in unbroken pieces without being scraped off or made to particles.

    摘要： When splicing optical fibers (1, 1') by melt-fusioning in an electric arc (7), the electric arc (7) is started, in order to give the fiber splice a large strength, before the ends of the fibers (1, 1') have entered the arc (7) and before they have contacted each other. The arc (7) is in this stage switched on with a low intensity which is increased in the stage when the fiber ends are fusioned to each other. When the electric arc (7) is established having this low intensity and immediately before the contact of the end surfaces and the melt-fusioning, the fiber ends are finely aligned with each other in the lateral direction. It can be performed by means of the optical system and the control means which are provided in commercially available fiber welding apparatus, and the fine alignment will give the splice a low attenuation. For standard fibers of the single-mode type a welding current through the electrodes (5) of approximately 6.5 mA is suitable.
