ABSTRACT:
In accordance with the invention, the polymeric coating is removed from a coated optical fiber by disposing the fiber within a non-oxidizing environment and applying sufficient heat to volatilize at least a portion of the polymeric coating. The result is that the coating material bursts from the fiber, yielding a clean glass surface virtually free of surface flaws. In a preferred embodiment the non-oxidizing environment is inert gas and the heat is provided by resistive filament heaters.
