  • Light waveguide lead having a filling compound and method for manufacture of the lead
    Patent number: 5335302
    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.
