An adhesive binder for optical fiber packages is described which comprises a silicone-epoxy IPN (Interpenetrating Polymer Network), with the epoxy cured to give reinforcing domains within the cured silicone. The adhesive binder is prepared by cross-linking and polymerizing a silicone polymer and an epoxy resin, with a cross-linking agent and a catalyst for curing the epoxy and silicone, optionally with the addition of a silane wetting agent, such as methacryloxypropyl trimethoxysilane. In preparing a wound optical fiber package, the adhesive binder is applied in solution to the fiber, during its winding, by passing the fiber through the solution or by brushing the solution on each layer when its winding is completed.
