  • Patent number: 8611712
    Abstract: A rubber member optically connects (a) an optical transmission medium or an optical component and (b) another optical transmission medium or another optical component by intervening between the (a) and the (b). An adhesive connecting member comprises a rubber member having a refractive index of 1.35 to 1.55 and an adhesive having a refractive index of 1.35 to 1.55.
    Type: Grant
    Filed: March 24, 2009
    Date of Patent: December 17, 2013
    Assignee: Tomoegawa Co., Ltd.
    Inventors: Nobuhiro Hashimoto, Tomoki Furue, Makoto Gotou
  • Patent number: 7985461
    Abstract: An adhesive connecting member and an optical connecting structure using the member, in which connection loss can be reduced and handling is facilitated, are provided. The adhesive connecting member optically connects an optical transmission medium and another optical transmission medium or an optical part by being intervened therebetween, and the member has a strongly adhesive face contacting the optical transmission medium and a weakly adhesive face contacting the other optical transmission medium or optical part. In addition, by this adhesive connecting member, the optical transmission medium and the other transmission medium or optical part can be optically connected.

  • Patent number: 7936958
    Abstract: An optical fiber coil and a production method therefor reduce the likelihood of optical transmission loss due to stress or temperature changes at low cost. Plural single optical fibers are arranged in parallel and are integrally covered with a covering portion so as to form an optical fiber ribbon, and the optical fiber ribbon is wound into a coiled state.

  • Patent number: 7899284
    Abstract: The present invention provides a process for producing an optical connector, an apparatus for producing the same, and a process for forming a polymer coating film on an end face of a fibrous dielectric, which can dispose a refractive index adjuster only onto an end face of an optical transmitting medium with excellent reproducibility. Such a process includes bringing an end surface of the optical transmitting medium close to an end face of a liquid refractive index adjuster, while charging at least one of the optical transmitting medium and the liquid refractive index adjuster, thereby adhering the liquid refractive index adjuster to the end face of the optical transmitting medium, and thereafter solidifying the adhered liquid refractive index adjuster to obtain the refractive index adjuster.

  • Publication number: 20090142023
    Abstract: A production method for an optical connecting part including an optical transmission medium having an end surface provided with a refractive index matching member, includes a step for arranging a charging device in the vicinity of the optical transmission medium and the vicinity of a dielectric member. The method also includes a step for charging the optical transmission medium by the charging device, and includes a step for supplying the refractive index matching member to the end surface of the optical transmission medium.
