    Abstract: A holding device 10 includes a supporting member 12 for supporting an optical fiber cord 1 and a fixing member 14 for fixing optical fiber cord 1 to supporting member 12. Supporting member 12 includes a hitching section 16 for hitching a jacket end 5 configured by turning back a tension member 3 exposed outside a jacket 4 onto an outer surface of jacket 4, in a manner as to prevent optical fiber cord 1 from falling off from supporting member 12 due to at least a weight of optical fiber cord 1. Fixing member 14 includes a pressing section 18 acting to deform hitching section 16 hitching jacket end 5 by a pressing force to make hitching section 16 closely contact with jacket end 5. Pressing section 18 exerts pressing force dependently on a dimensional difference between hitching section 16 and pressing section 18, so as to compress hitching section 16.

    Abstract: A low-profile, mass-producible, unitary injection molded optical ribbon attachment structure includes a ribbon retaining portion, a light reflecting portion, and a plurality of lens portions. An end portion of a fiber optic ribbon cable is disposed in a ribbon retaining groove in the ribbon retaining portion. The unitary structure is fixed onto a bottom major surface of a circuit board. In a transmit application, light emitted from an optoelectronic component disposed on a top major surface of the circuit board passes down through a hole or slit in the circuit board, into one of the lens portions, then reflects off a planar light reflecting surface of the light reflecting portion and is redirected approximately ninety degrees, and then passes substantially parallel to the bottom major surface of the circuit board and enters the end of the fiber optic ribbon cable. In a receive example, light passes the opposite direction.

  • Patent number: 7753597
    Abstract: An apparatus for splicing of optical waveguide sections is in the form of a handheld splicer. The splicer comprises a preprocessing unit, which may comprise a plurality of processing devices for carrying out removal, cleaning and cutting steps. The optical waveguide sections are clamped in a holding apparatus and are prepared in the preprocessing unit. The holding apparatuses are inserted with the prepared optical waveguide sections into a splicing unit, where they are spliced. The spliced optical waveguide sections can be fed by means of a transfer station to a shrinking oven for shrinking a shrink sleeve on. The preprocessing unit, the splicing unit and the shrinking oven can be controlled by means of one hand of an operator, while the splicer is held with the other hand.

  • Patent number: 7751675
    Abstract: The present disclosure relates to a wall box adapted to be mounted at a mid-span access location of a fiber optic telecommunications cable. The wall box includes an enclosure having a main body with an open front side. The enclosure also includes a front cover for opening and closing the open front side of the main body. The wall box defining first and second cable entrance/exit openings positioned at opposite sides of the enclosure. The main body defines an open region through an exterior wall of the main body. The open region extends from the first cable entrance/exit opening to the second cable entrance/exit opening. The enclosure also includes a cable cover that is mounted to the main body to cover the open region. The cable cover is a separate component from the front cover.

  • Patent number: 7742675
    Abstract: A telecommunications cable management system includes trough elements including a planar top surface and sides for cable routing and management. The trough elements are made from separate parts assembled together with a mating arrangement. The mating arrangement allows assembly of the system on site, such as by snapping the parts together. The trough elements are then assembled together to form the cable management system.

  • Publication number: 20100150516
    Abstract: A manifold for holding spliced optical fibers contained within fiberoptic ribbons in a secure and motionless manner. The manifold includes a “clamp” made from soft durometer material (SDM) such as high strength silicone mold-making rubber or dry polymer gel that has been partially sliced to a depth of about 75%. The manifold permits ease of insertion of a spliced optical fiber by itself, or a fiber associated with a ribbon, into, and removal from, an SDM-slice without disturbing other fibers, or ribbons, respectively, that are held in other slices in the manifold. In a particular embodiment SDM fills a four-sided hard plastic box to overflow. Slices in SDM are parallel to each other. The box has a hinged cover to exert pressure on overflow SDM material when the cover is closed to increase enveloping force on splice-junctions of embedded bare-glass optical fibers and on the ribbons containing those fibers.
