Abstract: A fiber optic connector assembly and method employing one or more fiber movement supports. The one or more fiber movement supports are each disposed around one or more optical fibers and are configured to inhibit kinks or sharp bends from occurring in the one or more optical fibers. The fiber movement support is more rigid than an optical fiber. Thus, when a force is exerted on an optical fiber in a direction angled to the axis of the optical fiber, the force is directed to the fiber movement support. The fiber movement support translates the non-axial force in a direction toward the axis of the optical fiber. This causes the optical fiber to be pushed back towards the fiber optic cable instead of the kinking or bending the optical fiber, thus avoiding or reducing high insertion losses resulting from bending of the optical fiber.
