Publication number: 20240004136Abstract: A system of aligning concatenated sections of multicore optical fiber incorporates the capability of intentionally changing core assignments as part of the azimuthal alignment process. The intentional changing of core assignments, referred to as offset clocking, compensates for differences in properties of the individual core regions in a way that reduces variations between the spatial channels supported in the transmission system. The offset clocking technique can be used, e.g., to improve the attenuation (or other selected properties of the propagating signals). The offset clocking technique may be used to step through sequential changes core assignments at one or more splice locations (passive clocking) or identify a particular pairing of cores from one fiber section to the next (e.g., “good quality” core assigned to a “poor quality” signal exiting the first section) and rotate the fiber sections with respect to each other to achieve this particular core assignment.Type: ApplicationFiled: December 6, 2021Publication date: January 4, 2024Applicant: OFS Fitel, LLCInventors: Tristan Kremp, Yue Liang, Robert L Lingle

Patent number: 11163324Abstract: An optical probe includes an optical source that generates an optical beam that propagates from a proximal end to a distal end of an optical fiber that imparts a transformation of a spatial profile of the optical beam. An optical control device imparts a compensating spatial profile on the optical beam that at least partially compensates for the transformation of the spatial profile of the optical beam imparted by the optical fiber in response to a control signal from a signal processor. A distal optical source generates a calibration light that propagates through the one or more optical waveguides from the distal end to the proximal end of the optical fiber. An optical detector detects the calibration light and generates electrical signals in response to the detected calibration light.Type: GrantFiled: September 29, 2020Date of Patent: November 2, 2021Assignee: OFS FITEL, LLCInventors: Eric Swanson, Tristan Kremp, Paul S Westbrook, David J DiGiovanni

Patent number: 11156768Abstract: A hollow core optical fiber and cable combination is configured to exhibit minimal SNR and loss degradation. This is achieved by either: (1) reducing the coupling between the fundamental and other (unwanted) modes propagating within the hollow core fiber; or (2) increasing the propagation loss along the alternative. The first approach may be achieved by designing the cable to minimize perturbations and/or designing the hollow core fiber to fully separate the fundamental mode from the unwanted modes so as to reduce coupling into the unwanted modes. Whether through fiber design or cable design, the amount of light coupled into unwanted modes is reduced to acceptable levels. The second approach may be realized through either fiber design and/or cable design to suppress the light in unwanted modes so that an acceptably low level of light is coupled back into the fundamental mode.Type: GrantFiled: May 18, 2020Date of Patent: October 26, 2021Assignee: CFS FITEL, LLCInventors: David J DiGiovanni, Daryl Inniss, Brian Mangan, Vitaly Mikhailov, John E.

Publication number: 20200079680Abstract: A process of fabricating the microstructure core rod preform used in the fabrication of a hollow core optical fiber includes the step of applying external pressure to selected hollow regions during the drawing of the preform from the initial assembly of capillary tubes. The application of pressure assists the selected hollow regions in maintaining their shape as much as possible during draw, and reduces distortions in the microstructure cells in close proximity to the core by controlling glass distribution during MCR draw.Type: ApplicationFiled: September 12, 2018Publication date: March 12, 2020Applicant: OFS Fitel, LLCInventors: Matt Corrado, David J DiGiovanni, Brian Mangan, Gabriel Puc, Robert S Windeler, Tristan Kremp
