By this adjustment, markings 6 formed on each optical fiber wire 2 (2A to 2D) can be aligned with the corresponding markings 6 formed on the other fiber wires 2 to the same position.

  • Patent number: 8606063
    Abstract: Provided is a manufacturing method for an optical waveguide in which, when the optical waveguide is cut and a contour thereof is processed, accuracy of a cut position is improved by improving visibility of an alignment mark. An undercladding layer, cores, and alignment marks are formed on a front surface of a substrate. Then, an overcladding layer is formed using a photomask so as to cover the cores with the alignment marks being exposed. After the substrate is separated to manufacture an optical waveguide body, a cut position is located with reference to the alignment marks from a rear surface side of the undercladding layer, and the undercladding layer and the overcladding layer are cut to manufacture the optical waveguide.

  • Publication number: 20130323414
    Abstract: Adverse hydrogen aging limitations in multiply-doped optical fibers are overcome by passivating these optical fibers using a deuterium passivation process. This treatment essentially pre-reacts the glass with deuterium so that the most active glass sites are no longer available to react with hydrogen in service. Optical fibers of main interest are doped with mixtures of germanium and phosphorus. Optimum passivating process conditions are described.

  • Publication number: 20130315525
    Abstract: An optical apparatus comprises: a waveguide substrate, optical cladding formed on the substrate; a waveguide core formed within the cladding, an optically absorptive layer formed within the cladding, and a linearly polarized light source. The waveguide core includes an attenuating segment thereof, and the absorptive layer is formed near the attenuating segment of the core. The core and cladding are arranged to form an optical waveguide that supports a propagating optical mode. The absorptive layer is positioned near the attenuating segment of the core so as to spatially overlap a portion of the optical mode. The extent of the overlap results in a designed level of optical loss per unit distance of propagation of a linearly polarized optical signal along the attenuating segment of the optical core in the optical mode without substantial alteration of the polarization state of the optical signal.

    Abstract: An apparatus with: an extrusion head with a tip and a die concentrically arranged therewithin and extrudes a tube between the tip and the die; a needle that feeds at least one optical fiber and filler to be filled around the optical fiber into the tube being extrusion-molded; and a cylindrical bundling member provided within the needle. The bundling member has a bundling hole smaller than an inner diameter of the tube at a center thereof and into which the optical fiber can pass through, and a flow pass penetrating along a feeding direction of the filler between the bundling hole and an inner circumferential surface of the needle. In a method using the apparatus, the optical fiber is passed through a bundling hole to be bundled at a center of the tube. The filler is passed through a flow path to be filled around the optical fiber.

  • Patent number: 8574385
    Abstract: A communication line such as an optical fiber or cable is attached along a wall, ceiling, trim piece, or other target surface inside of a building by laying out the line from an applicator tool. An outer surface of the line is placed in a temporarily tacky condition as the line is laid out from the tool along the target surface. The temporarily tacky condition of the line is due at least in part to an adhesive component that is pre-applied to the outer surface of the line. The adhesive component is activated by an agent or medium that is associated with the applicator tool. The line becomes non-tacky after it is attached to the target surface.

    Abstract: A fiber optic cable includes a cable jacket and a core. The cable jacket is tubular, having exterior and interior surfaces, and is formed mostly from a first polymeric material. The jacket includes access features formed from a second polymeric material at least partially embedded in the first polymeric material and extending lengthwise along the jacket. Two of the access features are spaced apart from one another with a section of the jacket formed from the first polymeric material extending laterally therebetween, such that the section may be peeled apart from the rest of the cable lengthwise along the jacket by separation of the jacket about the access features. The core has an outermost surface and includes optical fibers and a strength member. The outermost surface of the core is at least partially bonded to the interior surface of the jacket, which enhances coupling between the jacket and core.
