  • Publication number: 20230273384
    Abstract: Embodiments of the disclosure relate to an optical fiber cable. The optical fiber cable includes a cable jacket having an interior surface and an exterior surface. The interior surface defines a central bore extending along a longitudinal axis of the optical fiber cable, and the exterior surface defines an outermost surface of the optical fiber cable. At least one subunit is disposed within the central bore. Each of the at least one subunit includes at least one optical fiber disposed within a buffer tube. A plurality of ultrahigh molecular weight polyethylene (UHMWPE) tensile yarns are positioned around the at least one subunit and extend along the longitudinal axis. A layer of a bedding compound is disposed between the plurality of UHMWPE tensile yarns and the cable jacket.

  • Patent number: 11579388
    Abstract: 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.
