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: The system and methods for marking an optical fiber with color-coded marks disclosed herein include forming closely spaced multiple ink streams, with at least two of the ink streams having different colors. The optical fiber moves over a fiber path that resides adjacent the ink streams. The fiber path and the ink streams are made to briefly intersect so that the ink streams form on the outer surface of the optical fiber a group of spaced apart individual marks, wherein the group of individual marks constitute a color-coded mark. Repeating this marking process at different times as the fiber moves over the fiber path forms spaced apart color-coded marks along the length of the fiber. Subsequent drying and overcoating of the marks fixes and protects the color-coded marks.

Abstract: In one embodiment, an apparatus for screen testing an optical fiber includes a fiber conveyance pathway, a capstan having an outer circumference and a fiber contact region extending around the outer circumference, the fiber contact region having a durometer hardness of less than or equal to about 40 Shore A, where the capstan is positioned adjacent to the fiber conveyance pathway such that when the optical fiber is directed over the fiber conveyance pathway, the optical fiber engages with the fiber contact region, and a pinch belt positioned adjacent to the fiber conveyance pathway such that the fiber conveyance pathway extends between the pinch belt and the fiber contact region, where the pinch belt is engagable with the fiber contact region such that, when the optical fiber is directed over the fiber conveyance pathway, the optical fiber is impinged between the pinch belt and the fiber contact region.
