Publication number: 20230350146Abstract: Embodiments of the disclosure relate to an optical fiber cable. The optical fiber cable includes a subunit having a first interior surface and a first exterior surface. The first interior surface defines a central bore along a longitudinal axis of the optical fiber cable. At least one optical fiber is disposed within the central bore of the subunit, and a plurality of strengthening yarns is disposed around the subunit. A cable sheath disposed around the plurality of strengthening yarns. The cable sheath has a second interior surface and a second exterior surface. The second exterior surface defines an outermost surface of the optical fiber cable. The cable sheath includes from 55% to 68% by weight of a mineral-based flame retardant additive and from 35% to 45% by weight of a polymer blend. The polymer blend includes a co-polyester or co-polyether and a polyolefin or a polyolefin elastomer.Type: ApplicationFiled: July 7, 2023Publication date: November 2, 2023Inventors: Michael Alexander Heinz, Ravinder Kumar Kinnera

Patent number: 11391900Abstract: Embodiments of the disclosure relate to an optical fiber cable. The optical fiber cable includes a cable sheath having an interior surface and an exterior surface. The interior surface defines a longitudinal bore and the exterior surface defines an outermost surface of the optical fiber cable. The optical fiber cable also includes a plurality of micromodules disposed within the longitudinal bore. Each micromodule of the plurality of micromodules includes a micromodule jacket surrounding at least one optical fiber. The micromodule jacket of each of the plurality of micromodules is made of a first polymer composition having a first melt temperature, and the cable sheath is made of a second polymer composition having a second melt temperature that is less than the first melt temperature. The first polymer composition and the second polymer compositions are both low smoke, zero halogen materials.Type: GrantFiled: November 6, 2020Date of Patent: July 19, 2022Assignee: CORNING RESEARCH & DEVELOPMENT CORPORATIONInventors: Michael Alexander Heinz, Ravinder Kumar Kinnera

Patent number: 10534149Abstract: A flame retardant and/or crush-resistant optical cable is provided. The cable includes a plurality of optical fibers and an inner jacket surrounding the plurality of optical fibers. The inner jacket includes an inner layer and an outer layer. The cable includes an armor layer surrounding the inner jacket. The cable includes an outer jacket surrounding the armor layer. The inner layer of the inner jacket, the outer layer of the inner jacket and/or the outer jacket are formed from one or more different material providing different properties to the cable. For example, the outer jacket may be formed from a flame-retardant, zero-halogen polymer material, the inner layer of the inner jacket may be chemically resistant to inorganic material, and the outer layer of the inner jacket may be chemically resistant to organic material.Type: GrantFiled: February 6, 2018Date of Patent: January 14, 2020Assignee: Corning Optical Communications LLCInventors: Holger Baetz, Anne Germaine Bringuier, Ravinder Kumar Kinnera, Wesley Brian Nicholson
