Patent number: 10534133Abstract: Methods for cleaving an optical fiber that extends from a ferrule are provided herein. The ferrule can be aligned on a first side of a scribe wire and an unconstrained end of the optical fiber on a second side of the scribe wire. Tension can be applied to the scribe wire with the optical fiber. Relative motion between the scribe wire and the optical fiber can be caused, while the tension is applied with the optical fiber. The scribe wire and the optical fiber can be separated. A fiber optic shard can be cleaved from the optical fiber. The fiber optic shard may include the unconstrained end of the optical fiber.Type: GrantFiled: November 6, 2017Date of Patent: January 14, 2020Assignee: Corning Optical Communications LLCInventors: Alvin John McDonald, Jeremy Jason Schermerhorn, Hieu Vinh Tran

Patent number: 9529152Abstract: A laser cleaving system includes a laser and a fixture including holders for respectively holding optical fiber ribbons at different angular positions. The fixture is rotatable relative to the laser for facilitating serial cleaving of the optical fiber ribbons. The fixture is configured for holding the ribbons in a predetermined manner so that the cleaved optical surfaces are of high quality and coplanar, such as when installed in a ferrule. For example, the fixture separates the ends of the ribbons from one another so that the ribbons being held by the fixture may be cleaved substantially independently from one another.Type: GrantFiled: October 31, 2014Date of Patent: December 27, 2016Assignee: Corning Optical Communications LLCInventors: Kenneth Todd James, Xin Liu, Alvin John McDonald
