Abstract
A light waveguide lead has at least one light waveguide accommodated within a protective sheath and this light waveguide is embedded in a pasty filling compound characterized by small balls being added to the compound, which balls are composed of a different material than the filling compound material. The diameter of the small balls and the number are selected so that the light waveguide has a displaceability within the filling compound that is adequate to allow stranding in other processes to the light waveguide lead.
Claims25
In a light waveguide lead comprising at least one light waveguide accommodated in a protective sheath and embedded in a pasty filling material, the improvements comprising the filling material having small balls embedded therein for formation of a lead filling compound, said small balls being composed of a different material than the filling material and the diameter of the small balls and their number being selected so that the light waveguide has a displaceability within the lead filling compound which is adequate for any movement applied to the light waveguide lead.
In a light waveguide lead according to clam 1, wherein the surface of the small balls is optimally smooth.
A method of manufacturing a light waveguide lead having an outer sheath with at least one light waveguide disposed therein and a lead filling compound comprising the steps of providing an extrusion head, conveying a light waveguide into the extrusion head and extruding a protective sheath around the light waveguide, conveying a lead filling compound having a filling material and small balls and introducing said compound into the protective sheath through the extruder head of the extruder.
