The present disclosure relates to optical fiber alignment devices and systems for use in implementing optical splices between optical fibers. In certain examples, the optical fiber alignment devices and systems can include fiber alignment structures capable of clamping optical fibers in a co-axially aligned orientation.

A method according to one embodiment includes steps of: preparing an optical module and optical fiber holding member; attaching a clip member to a receptacle of the optical module and the optical fiber holding member; and pressing the receptacle of the optical module and the optical fiber holding member from below and pressing the clip member from above. The pressing step has pressing the first flat surface of the receptacle and the second flat surface of the optical fiber holding member at the third flat surface of the clip member, and which performed until the first flat surface of the receptacle and the second flat surface of the optical fiber holding member establish parallelism with the third flat surface of the clip member by using a jig that changes the parallelism of the pressing surface.

An object is to provide a highly versatile local-light detection apparatus for an optical fiber capable of supporting various types of coated optical fibers.

A local-light detection apparatus for an optical fiber according to the present invention includes a first jig including a recess curved in a longitudinal direction of a coated optical fiber and an optical input and output device configured to make light incident on the coated optical fiber in which a bend is formed and to receive light leaking from the coated optical fiber, a second jig including a protrusion curved in the longitudinal direction of the coated optical fiber, the protrusion being configured to sandwich the coated optical fiber between the recess of the first jig and the protrusion, a presser configured to apply a pressing force in a direction in which the recess of the first jig and the protrusion of the second jig approach each other and to form the bend in the coated optical fiber, and fiber guides disposed at both ends of the recess of the first jig in the longitudinal direction of the coated optical fiber, and to arrange the coated optical fiber on a predetermined path on the recess of the first jig regardless of a diameter of the coated optical fiber when the presser forms the bend in the coated optical fiber.

A fiber optic cable assembly includes a fiber strand having a length extending proximally along an axis and terminating distally at a termination, and a ferrule proximate the termination, wherein the ferrule is frangible, configured to shear along the length of the fiber strand, inboard of the termination.

A portable device for attaching a connector to an optical fiber, the optical fiber having an end, the device comprising means for receiving the optical fiber at the end of the optical fiber; and a connector station for autonomously attaching the connector to the optical fiber.

An epoxy-free, high-durability and low-cost plastic optical fiber splice design and fabrication process which meets commercial airplane environmental requirements. The splice design: (1) does not require the use of epoxy to join the end faces of two plastic optical fibers together; (2) incorporates double-crimp rings to provide highly durable pull force for the plastic optical fibers that are joined together; (3) resolves any vibration problem at the plastic optical fiber end faces using a miniature stop inside a splice alignment sleeve; and (4) incorporates a splice alignment sleeve that can be mass produced using precision molding or three-dimensional printing processes.
