ABSTRACT:
A method for manufacturing distributor and mixer elements for optical communications technology, which elements have at least two glass fiber light waveguides fused to one another along a given segment, characterized by the steps of forming a preform by arranging at least two fiber optical rods to extend parallel to each other, fusing the arranged rods to one another in at least one sharply limited longitudinal area, then subsequently heating the preform and drawing the elements therefrom.
