ABSTRACT:
An optical fiber package (20) is provided by winding a plurality of convolutions in a plurality of layers on a bobbin. To each layer is applied an adhesive material (45) which in a preferred embodiment is a mixture comprising a reactive silicone copolymer resin, a solvent system which includes an aromatic constituent, a catalyst and a wetting agent. The mixture has a modulus behavior which is relatively stable with respect to time throughout a relatively wide operating temperature. Inasmuch as the solvent system and the method of application of the mixture are effective to control the rate of precipitation and the rate of cure of the silicone constituent, the surface roughness of the convolutions is controlled. After the desired number of convolutions have been wound, the package is subjected to a heat treatment which relieves stresses in the wound fiber and which completes the cure of the adhesive material. The adhesive material is effective to hold the convolutions together sufficiently to allow transport and deployment and to allow the convolutions constantly to be payed off over a relatively wide temperature range and over a relatively wide range of payout speeds without the use of excessive force and without breakage.
