Publication number: 20240036267Abstract: A method of terminating an optical fiber having an inner core with a fiber optic connector including a ferrule having a micro-bore and an end face with a mating location is disclosed. The method includes determining a bore bearing angle of a bore offset of the micro-bore in the ferrule; determining a core bearing angle of a core offset of the inner core in the optical fiber; orienting the ferrule and the optical fiber relative to each other to minimize the distance between the inner core and the mating location; heating the ferrule to an processing temperature above room temperature; and coupling the optical fiber to the micro-bore of the ferrule. The size of the micro-bores and optical fibers may be selected to maximize the number of interference fits in a population of ferrules and optical fibers while minimizing failed fittings between the ferrules and optical fibers in the populations.Type: ApplicationFiled: October 13, 2023Publication date: February 1, 2024Inventors: Raisa Rose Boben, Woraphat Dockchoorung, Riley Saunders Freeland, Klaus Hartkorn, Mark Alan McDermott, Aislin Karina Sullivan, Pushkar Tandon

Publication number: 20230168442Abstract: An optical fiber connector comprises a multi-fiber ferrule having an array of grooves recessed relative to an upper surface of a medial portion thereof, wherein each groove has a depth greater than a maximum diameter of an uncoated fiber segment received therein, and is shaped such that an optical fiber received therein lacks contact with the groove over large arc length thereof (e.g., an arc spanning at least 120 or at least 150 degrees). A method for fabricating a multi-fiber connector with a multi-fiber ferrule includes flexing a medial portion of the ferrule into a non-linear configuration to expand an average width of at least some grooves defined in an upper surface of a medial portion thereof, receiving optical fibers in the grooves, pushing the fibers away from the bottom of each groove, and securing the optical fibers in the grooves.Type: ApplicationFiled: November 2, 2022Publication date: June 1, 2023Inventors: Thierry Luc Alain Dannoux, Riley Saunders Freeland

Patent number: 10788627Abstract: A fiber bulge (“bulge”) formed in an end of an optical fiber for positioning the optical fiber in a ferrule bore is disclosed. An energy source is controlled to direct focused energy to the end of the optical fiber extended from the front end face of the ferrule to expose and melt the end of the optical fiber into a bulge of desired geometry and size. The bulge comprises a cross-sectional region having an outer surface having a minimum outer diameter larger than the inner diameter of the ferrule bore. Thus, the optical fiber may be pulled back in the ferrule bore such that at least a portion of the outer surface of the interface region of the bulge interferes with and engages the front opening of the ferrule bore to position the fiber core within the ferrule bore.Type: GrantFiled: November 15, 2018Date of Patent: September 29, 2020Assignee: Corning Optical Communications LLCInventors: Venkata Adiseshaiah Bhagavatula, Woraphat Dockchoorung, Riley Saunders Freeland, Klaus Hartkorn
