  • Patent number: 10274683
    Abstract: The present invention provides a spring bias that is particularly suited for use to preload a low profile ferrule of an optical connector. In accordance with the present invention, an axial preload is applied to a connector ferrule by a spring structure provided external of the connector. In one embodiment, spring structure is provided outside a plurality of optical fiber connectors, which provides axial preload of multiple ferrules. Each ferrule could be of the type that supports a plurality of optical fibers of a fiber cable. In one embodiment, the spring bias is effected by a planar flexure external of the connector. The ferrule is coupled to the planar flexure with its longitudinal axis through the center of the planar flexure.

  • 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.
