  • Publication number: 20080166085
    Abstract: A receptacle type semiconductor laser module (TOSA) includes a semiconductor laser, a lens, and a fiber stub. The fiber stub has a slantwise cut surface to which a emission light emitted from the semiconductor laser and passing through the lens is incident. The cut surface is arranged in a position deviated from the focus of the lens in the direction of the optical axis of the fiber stub. The semiconductor laser module further includes a fixed optical attenuator arranged on a path of an emission light of the semiconductor laser and having an incident surface being oblique to an optical axis of the semiconductor laser. By such a configuration, a coupling fluctuation caused by an eccentricity of the optical fiber cord connected to the fiber stub and a near-end reflection can be suppressed.

  • Publication number: 20070299575
    Abstract: A remote troubleshooting system comprises a vehicle that transmits vehicle data regarding a stress factor of a specific onboard component at a specified timing, and a troubleshooting server that is connected to the vehicle via a network, receives the vehicle data from the vehicle, and performs the troubleshooting of the onboard component. The server determines a precaution level based on the vehicle data from the vehicle, selects a troubleshooting program that is suitable to the precaution level determined, and transmits this to the vehicle. The vehicle replaces the troubleshooting program currently stored by a memory with the troubleshooting program received. Thereby, the reliability of the troubleshooting can be improved.
