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.
