Abstract: A system and method in accordance with the present invention applies short bursts of a high temperature fluid to a hydrogen-loaded fiber to relocate the hydrogen within the fiber in the proximity of the fiber's core—to achieve a fiber having significantly improved photosensitivity. A stronger fiber grating is realized when the fiber is subsequently exposed to ultraviolet light.

Abstract: A system and method are provided for stripping one or more optical fibers having multiple coatings, accomplished with multiple stripping steps or passes. As an example, each coating may be stripped relatively independently. Such stripping may be accomplished with multiple bursts of a fluid or gas heated to a temperature sufficient to remove the coating.

Abstract: A system for stripping an optical fiber includes a source of air and means for generating very short bursts of air. A heater heats the bursts of air to a temperature sufficient to remove the outer coating from an optical fiber, while maintaining the air isolated from the heat source. A single burst of heated air removes the outer coating of an optical fiber, within less than about one second. A series of closely spaced bursts or a prolonged burst of heated air may be used to remove an expanded length of fiber coating. Stripping may include translation of the fiber or the heater or portions thereof. The stripper may be configured to strip several loaded fibers or a single fiber.

Abstract: A system and method for quickly heating a shrinkable casing around a relatively non-shrinkable object. As one example, the present invention may be used to shrink a sleeve around a strand, such as fiber or copper. A contact approach to heating the a loaded sleeve is used wherein a predetermined temperature profile is applied to prevent the trapping of air during shrinking. The thermal profile may be selectively controlled by the application of a fluid to the junction where heat is applied to the loaded sleeve.

Abstract: A system and method for quickly heating a shrinkable casing around a relatively non-shrinkable object. The system may be referred to as a sleeve shrinking quick dip heat system. As one example, the present invention may be used to shrink a sleeve around a strand, such as fiber or copper. In the electrical and electronic fields, the present invention may be used to shrink sleeves or tubing around, for example, copper strands, wires, connectors, or components. A contact approach to heating the a loaded sleeve is used wherein a predetermined temperature profile is applied to prevent the trapping of air during shrinking. Ramp-up time is eliminated by use of a heater block that remains near or at heat shrinking temperatures, while selectively transferring heat to the sleeve according to the desired temperature profile.

Abstract: A system for stripping an optical fiber includes a source air, and means for generating very short bursts of air. A heater heats the bursts of air to a temperature sufficient to remove the outer coating from an optical fiber, while maintaining the air isolated from the heat source. The heater includes a heater core that includes a heat generating element such as a conductive filament, and a heat chamber enclosed within the heater core. A spiral-shaped air conduit surrounds the outer surface of the heater core, and communicates with the heat chamber. Upon injection of air into the conduit, heat is transferred to the air from the heat generating element while the air flows through the air conduit and into and out of the chamber. A single burst of heated air removes the outer coating of an optical fiber, within less than one second.
