Abstract (en)
[origin: WO2005025842A2] The invention relates to the production of an optical transmission element (BA), comprising at least one optical waveguide (LW) and a chamber element (AH), surrounding the optical waveguide, enclosing an internal space. A foamed filler (FM) is intermittently applied to the optical waveguide (LW) and the optical waveguide (LW) then introduced into an extruder (EX), forming a chamber element (AH) around the optical waveguide. The filler (FM) is stabilised within the formed chamber element (AH) and gives, in the final state, several dry compressible filler elements (FE, FE1 to FE4), each enclosing the optical waveguide. A dry and easily manipulated optical transmission element is thus provided. An outflow of filler and an escape of the optical waveguide from the transmission element are prevented.
