  • Light waveguide having three protective layers of plastic material and a method of manufacture
    Patent number: 4854668
    Abstract: An optical fiber having a multiple layer coating characterized by the inside layer being composed of a material that is stretched onto the bare fiber. Preferably, the inside layer is applied by extruding a stretch cone and stretching this onto the fiber. An intermediate layer can be applied onto the inside layer, either by a pressure molding system or by a stretched cone method, and an outside layer is applied by another extruder forming a stretched cone.
