Abstract
A method of treating a buffered optical fiber or jacketed cable having a relatively low surface energy, e.g., fibers or cables that meet low smoke zero halogen (LSZH) standards, so they can be bonded to a supporting substrate at a customer premises by a water soluble, non-flammable adhesive. One or more burners produce a flame that treats the surface of the fiber or cable by oxidizing the surface as the fiber or cable moves past the burners. The surface energy increases enough for the adhesive to wet the surface so that, when cured, the adhesive bonds the fiber or cable to the supporting substrate. In another embodiment, a blown-ion discharge is directed at a determined rate over the surface of the fiber or cable, thereby treating the surface by removing contamination and micro-etching, and increasing the surface energy enough for the adhesive to wet the surface.
