Patent number: 11620810Abstract: A system (100) for the identification of the formation of a burning droplet (9) of a material of a fiber optic cable (3) during cable burn testing comprises a data processing device (11) for processing respective image data of a plurality of image samples of an image stream. The data processing device (11) is configured to execute at least a processing step of preprocessing each of the recorded image samples of the image stream to generate a respective preprocessed image sample for each of the recorded image samples such that areas of the recorded image samples disturbing the identification of burning droplets (9) are masked out in the respective preprocessed image sample, and a step of identifying a burning droplet (9) in each of the preprocessed image samples by evaluating a pixel color property of a pixel of each preprocessed image sample.Type: GrantFiled: November 10, 2021Date of Patent: April 4, 2023Assignee: CORNING RESEARCH & DEVELOPMENT CORPORATIONInventors: Robert Klares, Kirsten Langfeld, Thomas Meyer, Waldemar Stöcklein, Uwe Zymnossek

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: 10538653Abstract: A flame retardant compound is provided. The flame retardant compound includes a polymer base resin, a carbonific host compound, and a guest compound including at least one atom of a transition metal. The carbonific host compound and the guest compound form a host-guest complex, and the host-guest complex acts to inhibit at least one of smoke release and smoke formation when exposed to heat. The host-guest complex is distributed within the polymer base resin. An intumescent flame retardant compound is also provided. The intumescent flame retardant compound includes a base resin, an acid donor, a spumific agent, a cyclodextrin host compound, and a guest compound including at least one atom of molybdenum. The cyclodextrin host compound and the guest compound form a host-guest complex. The acid donor, carbonific host compound, and spumific agent react when exposed to a temperature above 280° C. to form a foam.Type: GrantFiled: August 28, 2019Date of Patent: January 21, 2020Assignee: CORNING OPTICAL COMMUNICATIONS LLCInventors: Dayue Jiang, Kirsten Langfeld, Brandon Robert Williamson
