Abstract: A method of marking an optical fiber is disclosed, wherein the method includes forming an ink stream, moving an optical fiber over a fiber path that resides adjacent the ink stream, and periodically changing the position of the fiber path so that the optical fiber at least partially enters the ink stream so that the ink from the ink stream forms spaced apart marks on the outer surface of the optical fiber. An optical fiber marking apparatus is also disclosed that includes payout and take modules that move the optical fiber over the fiber path, a marking unit configured to form an ink stream adjacent the fiber path, and a fiber positioning device that causes the optical fiber to periodically intersect the ink stream so that ink from the ink stream forms spaced apart marks on the outer surface of the optical fiber.

Abstract: A method of marking an optical fiber includes forming an ink stream, moving an optical fiber over a fiber path adjacent the ink stream, and intermittently deflecting the ink stream with a gas jet so that the optical fiber at least partially enters the deflected ink stream so that the ink from the deflected ink stream forms spaced apart marks on the optical fiber outer surface. An optical fiber marking apparatus is also disclosed that includes payout and take modules that move the optical fiber over the fiber path, a marking unit configured to form an ink stream adjacent the fiber path, and an ink stream deflection device that causes the ink stream to deflect and overlap the fiber path so that ink from the ink stream forms spaced apart marks on the outer surface of the optical fiber.

Abstract: The apparatus and methods include moving an optical fiber over a fiber path that includes a marking location at which resides a printer unit. The moving optical fiber has an amount of undamped fiber vibration that can exceed a fiber vibration tolerance at high fiber speeds. The printer unit is configured to dispense ink onto the optical fiber to form wet ink marks along the optical fiber as it moves past the marking location. The wet ink marks are dried and counted for quality control. The marked optical fiber is then covered with an overcoat to protect the ink marks. A position sensor measures an amount of vibration of the optical fiber substantially at the marking location. One or more vibration dampers disposed along the fiber path are used to reduce the fiber vibration below the fiber vibration tolerance. This allows for high-speed marking of the optical fiber.
