Patent number: RE42094Abstract: Methods are provided for validating the continuity of one or more optical fibers upon which a fiber optic connector is mounted. Typically, the fiber optic connector is mounted upon an optical field fiber by actuating a cam mechanism to secure the optical field fiber in position relative to an optical fiber stub. If subsequent testing indicates that the continuity of the optical field fiber and the optical fiber stub is unacceptable, the cam mechanism can be deactuated, the optical field fiber can be repositioned and the cam mechanism can be reactuated without having to remove and replace the fiber optic connector.Type: GrantFiled: November 30, 2005Date of Patent: February 1, 2011Assignee: Corning Cable Systems LLCInventors: Brandon A.
