Patent number: 11960132Abstract: A communication cable is provided that retains low signal attenuation even after multiple cycles through significant temperature changes. The cable includes a communication element, a tight buffer element that surrounds the communication element, a strengthening element that surrounds the tight buffer element, an inner jacket that surrounds the strengthening element, and an outer jacket that surrounds the inner jacket. The outer jacket protects the interior components and is made of a hard material, and the inner jacket protects the communication element from the mechanical stresses of temperature-induced thermal expansion and contraction of the outer jacket.Type: GrantFiled: September 19, 2022Date of Patent: April 16, 2024Assignee: CORNING RESEARCH & DEVELOPMENT CORPORATIONInventors: Sebastian Olszewski, Marta Krystyna Tomczak

Publication number: 20240103240Abstract: A fiber optic cable includes a core comprising a plurality of cable subunits configured such that an outer group of cable subunits surrounds a central cable subunit. each cable subunit includes one or more optical fibers, a buffer tube surrounding the one or more optical fibers, a strength layer surrounding the buffer tube, and a subunit jacket surrounding the strength layer. A thin film outer sheath surrounds the core, wherein the thin film outer sheath loads the outer group of cable subunits normally to the central cable subunit such that contact between the outer group of cable subunits and the central cable subunit provides coupling therebetween, limiting axial migration of the outer group of cable subunits relative to the central cable subunit.Type: ApplicationFiled: December 4, 2023Publication date: March 28, 2024Inventors: Mateusz Chmurski, Dorota Lagwa, Sebastian Olszewski, Tomasz Stolarczyk

A plurality of optical fibers (N) are disposed within the at least one buffer tube. Each optical fiber has a fiber diameter of 160 microns to 200 microns. The plurality of optical fibers have a total fiber area (AF). The buffer tube has a free space (1?AF/ATube, ID) of at least 37%, and the optical fiber cable has a fiber density (N/AC) of at least 3.25 fibers/mm2.Type: ApplicationFiled: November 21, 2023Publication date: March 21, 2024Inventors: Leigh Rooker Josey, Snigdharaj Kumar Mishra, Sebastian Olszewski, David Alan Seddon, Pushkar Tandon

Patent number: 9784935Abstract: A fiber optic cable comprises a core subassembly comprising at least one optical fiber and a tube surrounding the optical fiber. A multi-layered jacket surrounds the core subassembly, wherein the jacket comprises an inner layer comprising a flame retardant (FR) material and an outer layer comprising a non flame retardant material having a lower coefficient of friction than the flame retardant material. A method of manufacturing an optical fiber cable includes providing a core subassembly and co-extruding a multi-layered jacket around the core subassembly, wherein the multi-layered jacket includes an inner layer comprising a flame retardant (FR) material and an outer layer comprising a non flame retardant material having a lower coefficient of friction than the flame retardant.Type: GrantFiled: November 1, 2016Date of Patent: October 10, 2017Assignee: Corning Optical Communicaitons LLCInventors: Anne Germaine Bringuier, Anna Lipiec, Allen Michael Miller, Sebastian Olszewski, Katarzyna Synowiec

Patent number: 9669592Abstract: A method of manufacturing a fiber optic cable includes manufacturing a subunit and manufacturing an outer portion. Manufacturing the subunit includes extruding a subunit jacket over a first reinforcement material constraining an optical fiber. Manufacturing the outer portion of the fiber optic cable includes extruding an outer jacket over a second reinforcement material between the outer jacket and the subunit jacket. Hoop stress is applied to the second reinforcement material by the outer jacket, which constrains the second reinforcement material such that it is positioned and oriented to provide anti-buckling support to the fiber optic cable and mitigate effects on the optical fiber of jacket shrinkage due to low temperatures.Type: GrantFiled: March 12, 2014Date of Patent: June 6, 2017Assignee: CORNING OPTICAL COMMUNICATIONS LLCInventors: Bradley Jerome Blazer, Andrew S Dodd, Dieter Erwin Kundis, Sebastian Olszewski
