20090116793OPTICAL CONNECTOR - An optical connector of a fitting pin positioning type includes multiple optical fiber insertion holes arranged in one row and fitting holes or fitting pins. The fitting holes or the fitting pins for positioning are respectively disposed on mutually opposite sides of a straight line connecting centers of the optical fiber insertion holes and are located point-symmetrically with respect to a center of the row of the entire optical fiber insertion holes arranged on the straight line.05-07-2009
20090196556OPTICAL TRANSCEIVER AND OPTICAL CONNECTOR - An optical transceiver 08-06-2009
20090245737CONNECTOR HOLDER, OPTICAL-ELECTRICAL CONVERTER WITH ATTACHED CONNECTOR HOLDER, OPTICAL CONNECTOR FIXING STRUCTURE AND CONNECTOR HOLDER ASSEMBLY METHOD - A connector holder fixes an optical connector assembled at a leading end of an optical fiber to an optical module having a light input/output end so that the optical fiber and the light input/output end is optically connected. The connector holder is provided with a holding section for storing at least a part of the optical connector, and a cover section attached to the holding section to be freely opened and closed. The cover section is provided with a cover section main body, and a pressing section which presses the optical connector toward the optical module.10-01-2009
20090252455OPTICAL PATH CHANGING MEMBER - An optical path changing member is assembled at ends of optical fibers and placed to face a substrate including an optical input/output terminal having optical axes inclined with respect to optical axes of the ends. The optical path changing member is made of a transparent material and includes a member body having a reflection surface for optically connecting the ends to the optical input/output terminal. The member body has optical fiber insertion holes and an end placement portion to which the insertion holes are open and in which the end faces of the optical fibers are placed. The reflection surface is formed so that light entering from the end faces of the optical fibers into the member body will be internally reflected toward the optical input/output terminal in the member body. The end placement portion is filled with an adhesive by which the ends are fixed to the member body.10-08-2009
20090257718OPTICAL CONNECTOR HAVING OPTICAL FIBER - In an optical connector with optical fibers in which silica glass optical fibers with resin coating layers remaining attached are connected in optical fiber openings of a ferrule made from resin, at least a part of the resin coating layer of the optical fiber is glued to an inner face of the optical fiber opening, an outer diameter of the resin coating layer of the optical fiber is less than or equal to 125 μm, and the Young's modulus of the resin coating layer is less than the Young's modulus of the ferrule, and the Young's modulus of the resin coating layer is 1500 to 10000 MPa.10-15-2009
20100104245FERRULE FOR OPTICAL CONNECTOR - A ferrule includes a recess formed on an obliquely polished surface to house a protrusion formed on an obliquely polished surface of another ferrule, so as to avoid an angular change at an interface between end surfaces of the pair of obliquely polished end surfaces of the ferrules facing each other.04-29-2010
20100232743OPTICAL-PATH TURNING MEMBER AND OPTICAL-PATH TURNING OPTICAL CONNECTOR - In a light path converting member (09-16-2010
20110064353METHOD OF MANUFACTURING OPTICAL PATH CHANGE OPTICAL CONNECTOR, AND OPTICAL PATH CHANGE OPTICAL CONNECTOR - A method of manufacturing an optical path change optical connector, the method including: resin-molding a core part, the core part including an optical-fiber-hole-formed portion having an optical fiber hole, and a positioning structure portion for positioning the core part with respect to the circuit board; inserting an optical fiber into the optical fiber hole; and over-molding the core part with light-transmitting resin, covering a front end face of the optical-fiber-hole-formed portion and forming an inclined internal reflective surface opposite to the front end face of the optical-fiber-hole-formed portion, such that the inclined internal reflective surface is positioned to reflect light between the optical fiber inserted into the optical fiber hole and an optical element disposed on a circuit board on which the core part is mounted.03-17-2011
20110064358OPTICAL PATH CHANGE MEMBER AND HOLDING MEMBER BODY - Provided is an optical path change member including a holding member body formed of a transparent material. The holding member body includes: at least two rows of optical-fiber insertion holes which hold optical fibers inserted therein, such that the optical axes of the optical fibers are inclined with respect to an optical axis of the optical device, and a reflective inner surface which totally internally reflects light incident from the optical-fiber insertion holes to a surface of the holding member body configured to face an optical device on a board.03-17-2011
