Patent number: 11640031Abstract: The present disclosure relates to a process by which an optical fiber array is cleaved with a laser-cleaving apparatus. The coating material is stripped or removed from a section of an optical fiber array; a coated or ribbonized section of the optical fiber array is secured in a holder; the holder is aligned inside the laser-cleaving apparatus; the laser cleaves the stripped ends of the fibers in the optical fiber array; the laser-cleaved ends of the optical fibers are then mechanically separated to remove the free ends from the optical fibers in the optical fiber array, leaving a cleaved array of optical fibers. The cleaving process enables the optical fiber array to be cleaved at flexible locations along an optical fiber ribbon or optical fiber cable with no swelling, minimal cleave angle variation across the cores of the optical fibers, a controlled surface roughness of the optical fiber end-faces, and high process yield.Type: GrantFiled: May 17, 2021Date of Patent: May 2, 2023Assignee: Corning Research & Development CorporationInventors: Scott Robertson Bickham, Joel Patrick Carberry, Randy LaRue McClure, Craig John Mancusi Ungaro, Qi Wu, Lei Yuan

Patent number: 11619793Abstract: Examples of optical splitter systems, methods and modules enable the stacking and interconnecting of one or more optical splitter modules. One example of a splitter module has a housing and one or more connection members for connecting to adjacent instances of like splitter modules. The housing includes a plurality of cable ports providing access to an optical splitter storage area. Each connection member includes a tab and a slot, the tab configured to slidingly engage with the slot of an adjacent connection member. Sliding engagement of adjacent instances of splitter modules can form a stack of splitter modules along a stacking axis. In some cases a splitter module includes a latching mechanism to removably engage an adjacent splitter module. The latching mechanism can restrict sliding engagement and thus decoupling of the adjacent splitter modules.Type: GrantFiled: November 2, 2021Date of Patent: April 4, 2023Assignee: PPC BROADBAND, INC.Inventors: Nicholas B. Larsson, George I. Wakileh, Joselyn Gabriela Gamboa
