  • Patent number: 10739529
    Abstract: The ends of sensing and interrogating multicore fibers are brought into proximity for connection in a first orientation with one or more cores in the sensing fiber being paired up with corresponding one or more cores in the interrogating fiber. Optical interferometry is used to interrogate at least one core pair and to determine a first reflection value that represents a degree of alignment for the core pair in the first orientation. The relative position is adjusted between the ends of the fibers to a second orientation. Interferometry is used to interrogate the core pair and determine a second reflection value that represents a degree of alignment for the core pair in the second orientation. The first reflection value is compared with the second reflection value, and an aligned orientation is identified for connecting the sensing and interrogating fibers based on the comparison.

    Abstract: In an optical-connector-incorporating plug accommodating and holding an optical connector in a barrel at a front end thereof and accommodating, in the barrel, an extra length portion of an optical fiber extending from an optical cable to the optical connector, the extra length portion bends as the optical connector is moved toward a back end of the barrel when the optical connector is connected to a mating receptacle; the distance from the position where the optical connector is held to the outer wall of the barrel depends on the direction, among the directions orthogonal to the direction in which the optical connector is moved; and a guide portion guiding the bend of the extra length portion in a direction other than the direction where the distance to the outer wall of the barrel is the shortest is formed in the barrel. The optical-connector-incorporating plug can be reduced in size.

    Abstract: A fiber-optic conversion module is provided as part of a lighting device on a vehicle. The module includes optical fibers with connectors, a light exit head, and a converter mounted on a cooling element. Shorter wavelength excitation light is fed to the optical fibers that emit the excitation light towards the converter arranged at an angle relative to the beam direction, at a light spot that remits useful light in a radiation angle in form of a cone of useful light and reflects excitation light as a Fresnel reflection substantially outside the cone of useful light, where Fresnel reflection is made harmless by a light stop.

    Abstract: Multi-fiber, fiber optic cable assemblies may be configured so that the terminal ends of the cables have pre-assembled back-post assemblies that include pre-assembled ferrules, such as MPO ferrules that meet the requisite tolerances needed for fiber optic transmissions. To protect the pre-assembled components from damage prior to and during installation, pre-assembled components may be enclosed within a protective housing. The housing with pre-assembled components may be of a size smaller than fully assembled connectors so as to be sized to fit through a conduit. The remaining connector housing components for the multi-fiber connectors may be provided separately and may be configured to be attached to the back-post assembly after installation of the cable.

  • Patent number: 9690055
    Abstract: Systems and methods for bonding a bare fiber section within a longitudinal bore of a ferrule are disclosed. The methods include inserting the bare fiber section into the ferrule bore along with a photoactivated adhesive. A diverging beam of activating light is directed into an endface of the bare fiber section at the ferrule front end. The activating light passes through the bare fiber section to expose the surrounding photoactivated adhesive, thereby bonding the bare fiber section within the longitudinal bore. The ferrule and fiber can then be incorporated into an optical fiber connector.

  • Patent number: 8834036
    Abstract: An optical coupling structure of the present invention is configured with a lens body and a clamp. The lens body includes a lens section having the lens and a fixing section. The clamp includes a positioning section, a pressing spring, and a retaining section. The positioning section determines a position of the clamp except a position in a direction of the optical axis of the optical fiber. The pressing spring makes contact with a surface of the lens body having a normal direction matching with the end face of the optical fiber, and generates a returning force when the clamp moves in a direction opposite to the normal direction of the surface. The retaining section is formed in a portion of the clamp to press the optical fiber and retains the optical fiber not to move in a direction apart from the lens.

  • Publication number: 20140147078
    Abstract: Gradient index (GRIN) lens chips and associated small form factor optical arrays for optical connections, and related fiber optic connectors are disclosed. By aligning GRIN lenses within a GRIN lens chip, a more precise and reliable alignment may be achieved with respect to optical fibers than if a single conventional ferrule is utilized to align and secure both GRIN lenses and optical fibers. The GRIN lens chip may include a GRIN lens received and thereby aligned within a groove disposed between a fiber end and a terminal end of a GRIN lens holder body. The optical fibers may also be received and thereby aligned within a groove of a ferrule body. In this manner, when the GRIN lens chip containing the GRIN lenses is aligned with a ferrule body containing the optical fibers, then the GRIN lenses may be precisely located relative to the optical fibers.
