  • Patent number: 11327242
    Abstract: The present disclosure relates to a process by which an optical fiber is terminated with a ferrule to form an optical fiber connector assembly. The ferrule is heated at a heating temperature whereby the ferrule bore (and ferrule microhole) expands. The optical fiber is then inserted into the ferrule microhole. The ferrule then contracts when heat is no longer applied resulting in an interference fit between the optical fiber and the ferrule microhole based on the dimensions of the optical fiber and the ferrule microhole. The interference fit yields certain optical fiber characteristics within the optical fiber connector assembly. The present disclosure also relates to an optical fiber having an outer cladding comprising titania-doped silica and the resulting optical fiber characteristics.

  • Patent number: 10782485
    Abstract: Hardened fiber optic connectors having a mechanical splice assembly are disclosed. The mechanical splice assembly is attached to a first end of an optical waveguide such as an optical fiber of a fiber optic cable by way of a stub optical fiber, thereby connectorizing the hardened connector. In one embodiment, the hardened connector includes an inner housing having two shells for securing a tensile element of the cable and securing the mechanical splice assembly so that a ferrule assembly may translate. Further assembly of the hardened connector has the inner housing fitting into a shroud of the hardened connector. The shroud aides in mating the hardened connector with a complimentary device and the shroud may have any suitable configuration. The hardened connector may also include features for fiber buckling, sealing, cable strain relief or a pre-assembly for ease of installation.
