Abstract

A ferrule (4) for an optical waveguide (1), according to the invention, is characterised in that the ferrule (4) is made of plastics material, and in that the ferrule (4) is for example more transparent than the casing (2, 3) of the optical waveguide (1). The process according to the invention, for fixing a ferrule (4) to an optical waveguide (1), includes the following steps: stripping certain regions of an outer casing (2) of one end of the optical waveguide (1) and exposing an inner casing (3) of the optical waveguide (1); pushing the ferrule (4) onto the stripped region of the optical waveguide (1); and welding the ferrule (4), at least in certain regions, onto the surface of contact with the inner casing (3) of the optical waveguide (1). Because of the transparency of this ferrule (4), the laser light can almost completely penetrate the ferrule (4) in the so-called transmission technique and take effect in the outermost region of the casing (2, 3) of the optical waveguide (1).
