  • 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: 11092753
    Abstract: Optical filter devices for providing a reflective event in an optical network are disclosed. In one embodiment, the optical filter device comprises an optical filter assembly for reflecting one or more preselected wavelengths and a housing. In one embodiment, the housing comprises a plug end and a receptacle end for optical connection into a link or connection node of an optical network. The housing comprises a passageway between the plug end and the receptacle end, and the plug end comprises a shroud with a single fiber connector footprint. At least a portion of the optical filter assembly is disposed within the passageway of the housing. The optical filter devices disclosed allow the network operator the flexibility to choose where to position a reflective location in the optical network along with the ability to move, add or change the reflective location as desired.

  • Patent number: 11054586
    Abstract: An optical connector that requires fewer components and also has a simpler structure includes an optical fiber including a glass fiber and a resin coating surrounding the glass fiber; a ferrule having a flange outside the ferrule and a through-hole inside the ferrule, the ferrule holding, in the through-hole, a portion of the glass fiber exposed from the resin coating at an end of the optical fiber; a plug frame accommodating the ferrule; and an elastic member abutting the flange and biasing the ferrule. The flange has a flat surface on an outer periphery thereof, and the plug frame has a guide surface configured to unrotatably align the ferrule biased by the elastic member in contact with the flat surface of the flange. When the ferrule is moved in the direction opposite to the biasing direction, the flat surface is separated from the guide surface to bring the ferrule into a floating state relative to the plug frame.
