When a connector fixing member is inserted into an adaptor fixing member, a protruding section of the connector fixing member slides along an end surface of the adaptor fixing member, and is automatically guided to a notched section. | 2009-08-06 |
20090196555 | FLEXIBLY BENDED BOOT FOR OPTICAL FIBER CONNECTOR - A boot for an optical fiber connector according to the present invention is provided. The boot includes a hollow cylindrical body and a protrusion portion integrally formed on the hollow cylindrical body. In addition, a member with the property of plasticity is axially embedded in the protrusion portion so that the boot has the property of plasticity. | 2009-08-06 |

20090196557 | DUAL CONDUCTOR FIBER OPTIC CABLE - A powered fiber optic cable for use in a hydrocarbon well of extensive depth and/or deviation. The cable may couple to a downhole tool for deployment to well locations of over 30,000 feet in depth while maintaining effective surface communication and powering of the tool. The cable may be configured to optimize volume within a core thereof by employing semi-circular forward and return power conducting portions about a central fiber optic portion. As such, the cable may maintain a lightweight character and a low profile of less than about 0.5 inches in diameter in spite of powering requirements for the downhole tool or the extensive length of the cable itself. | 2009-08-06 |
20090196558 | Data communication cable comprising filling matrix and method of fabrication - A data communication cable can comprise multiple pairs of twisted conductors. A jacket that extends along the outside surface of the cable can define a longitudinal core, internal to the cable. The conductor pairs can be disposed in the core of the cable along with a foam matrix or a porous filler, with the matrix and the conductors occupying essentially all of the volume of the core. The foam matrix can hold each conductor pair in a respective location within the cable core to control signal crosstalk on each pair. A co-extrusion process can produce the cable via simultaneously extruding the foam matrix and the jacket. A pulling apparatus can feed the conductor pairs though respective ports of an extrusion head-and-die assembly. As one extruder encases the moving conductor pairs in the foam matrix, another extruder forms the jacket over the matrix and the embedded conductors. | 2009-08-06 |
20090196559 | Resin Composition for Optical Materials, Resin Film for Optical Material, and Optical Waveguide - A resin composition for an optical material, which is excellent in heat resistance and transparency and is soluble in an aqueous alkali solution, a resin film for an optical material made of the resin composition, and an optical waveguide using the same are provided. The resin composition for an optical material includes: (A) an alkali-soluble (meth)acrylate polymer containing a maleimide skeleton in a main chain; (B) a polymerizable compound; and (C) a polymerization initiator. The resin film for an optical material is made of the resin composition for an optical material. The optical waveguide has a core part and/or a clad layer formed using the resin composition for an optical material or the resin film for an optical material. | 2009-08-06 |
