  • Fiber guiding helical ring
    Patent number: 7274853
    Abstract: An apparatus and method for winding an optical fiber of arbitrary diameter on a smooth conical bobbin. The apparatus includes a slotted helical ring (148) attachable to, or integrated with a bobbin, the ring used to guide a fiber (152) in its initial first turn in the winding. After the first turn, the winding of a base layer and subsequent layers is achieved without needing a grooved bobbin surface.

  • System and method for winding a defect-free optical fiber on a bobbin
    Publication number: 20050178867
    Abstract: A system and method for winding a defect-free active optical fiber on a bobbin comprises a dummy layer serving as a base layer on the bobbin. The dummy layer can be wound on either a smooth or a grooved external surface of the bobbin, and the active fiber is wound over it, being guided by the structure of the dummy layer.
