  • Patent number: 9551843
    Abstract: When a moving member moves to a fixing position, a fixing member moves to a second fixing position, a blade of the fixing member cuts into a protection layer of a cord, and thereby the cord is fixed. When the moving member moves to a releasing position, the fixing member moves to a second releasing position, the blade leaves the protection layer, and thereby the cord is released.

  • Patent number: 9541719
    Abstract: A pluggable optical transceiver is disclosed. The optical transceiver provides a pull-tab assembled with a body of the transceiver. The pull-tab comprises a pair of arms and a handle. The arms in an end portion thereof each provides a leg set in a guide formed in the body. Sliding the pull-tab to disengage the optical transceiver from the cage, the leg is slid within the guide to push the end portion of the arm outwardly. The handle provides in an end thereof a bar including a slope. The optical fiber pulled out from the optical connector set in the optical receptacle of the transceiver rides on the slope even when the transceiver is set in the cage by the upside-down arrangement.

  • Patent number: 9417400
    Abstract: An optical connector has a housing, and a retention member for retaining a cable with a fiber that has a specified minimum bend radius. A rear portion of a connector ferrule and spring are seated in the retention member, a front end of the member engages the connector housing, and the spring urges the ferrule toward the front of the connector housing. An elongated cable support has an axial passage that opens at a front end and at a back end of the support for receiving the cable, and the front end of the support is joined at the rear of the retention member. The passage in the support has a radially outward flare at the back end which acts to limit the cable from bending in the vicinity of the connector, so that the cable fiber is not strained below the specified minimum bend radius.

  • Patent number: 9405078
    Abstract: There is described a method for terminating an optical fiber within a proximal portion of a guidewire tubing. The guidewire tubing has an outside diameter and comprises a lumen. The method comprises centering the optical fiber relative to the outside diameter of the proximal portion of the guidewire tubing. The optical fiber and the inside of the lumen define an average gap there between. The average gap around the optical fiber is between 1 ?m and 100 ?m for allowing a substantial displacement of the optical fiber inside the lumen during the centering.
