ABSTRACT:
An optical fiber package of this invention applies a friction enhancing material to the smooth surface of a bobbin or mandrel onto which the optical fiber is wound. The friction enhancing material adheres the initial layer of fiber to the smooth surface of the bobbin, thereby eliminating the need for an independent base structure for establishing and maintaining a winding path for the fiber. Furthermore, the friction enhancing material prevents the lateral movement at initial layer of fiber relative to the bobbin. In accordance with the present invention, the friction enhancing material is preferably a plastic material such as room temperature vulcanized (RTV) silicones and Styrene Butadiene Rubber (SBR) or the like. In addition, the optical fiber package of this invention may combine the use of both a friction enhancing material between the initial fiber layer and the bobbin, as well as an adhesive material coating applied along the length of the optical fiber. Accordingly, a stable package of elongated optical fiber strand material is established which may be used in situations or environments requiring rapid payout of the fiber without adversely effecting either the physical or the communicational properties of the fiber.
