Patent number: 11886027Abstract: An optical fiber cable includes a central strength member, a bedding compound surrounding the central strength member, a plurality of buffer tubes stranded around the central strength member and the bedding compound such that the bedding compound forms to the buffer tubes and occupies substantially the entirety of an inner core area between the buffer tubes and the central strength member. At least one of the buffer tubes contains a plurality of optical fibers and a jacket surrounds the plurality of buffer tubes. The cable may further include a second bedding compound that fills interstices in an outer core area between the buffer tubes and the jacket.Type: GrantFiled: May 21, 2020Date of Patent: January 30, 2024Assignee: CORNING OPTICAL COMMUNICATIONS LLCInventor: Michael Alexander Heinz

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: 11579388Abstract: An optical fiber cable comprises a cable core including at least one optical transmission element to transfer light, and a cable jacket surrounding the cable core. The cable jacket is embodied as a multilayered structure having a first sheath layer and at least a second sheath layer being surrounded by the first sheath layer. The material of the first and the second sheath layer is halogen free. The material of the first sheath layer and the material of the second sheath layer have a different flame retardant additive providing different flame retardant mechanisms.Type: GrantFiled: January 7, 2022Date of Patent: February 14, 2023Assignee: CORNING RESEARCH & DEVELOPMENT CORPORATIONInventors: Emanuela Gallo, Michael Alexander Heinz, Tomasz Kazmierczak, Kirsten Langfeld

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
