  • Patent number: 8538216
    Abstract: Fiber optic cables and assemblies for routing optical networks closer to the subscriber. The fiber optic cables have a small-cross section yet robust design that is versatile by allowing use in aerial application with a pressure clamp along with use in buried and/or duct applications. Additionally, the fiber optic cables and assemblies have a relatively large slack storage capacity for excess length. Assemblies include hardened connectors such as plugs and/or receptacles suitable for outdoor plant applications attached to one or more ends of the fiber optic cables for plug and play connectivity.

  • Publication number: 20120281955
    Abstract: Fiber optic bundles include helically stranded subunit cables. The assemblies have small cross sections and low bend radii while maintaining acceptable attenuation losses. Binders can be omitted to improve ease of processing and installation. Helically stranding of the subunit cables allows ease of access to the individual cables during installation.

  • Patent number: 7983520
    Abstract: Disclosed are fiber optic assemblies having at least one optical fiber and a water-swellable powder within a tube and/or cavity and methods for making the same. Fiber optic assemblies of the present invention use relatively low-levels of water-swellable powder while still effectively blocking the migration of tap water and/or saline solutions of 3% by weight along the tube and/or cavity. Furthermore, cleaning of the optical fibers is not necessary before connectorization like with conventional fiber optic cables that use a gel or grease. Generally speaking, at least some of the water-swellable powder is transferred to the inside surface of the tube, cavity, optical fiber or the like; rather, than being a loose powder that is able to migrate within the tube or cavity. Moreover, the existence of water-swellable powder within the fiber optic assembly or cable is nearly transparent to the craft since relatively low-levels are possible.

  • Patent number: 7555181
    Abstract: A distribution fiber optic cable including a plurality of optical fibers, a main cable body with some of the plurality of optical fibers being disposed within the main cable body, at least one tether optical fiber, and a cable jacket. The at least one tether optical fiber is one of the plurality of optical fibers that transitions during manufacturing from a first location within the main cable body to a tether access location for a portion of the distribution cable. The cable jacket includes a main cable body jacket and a tether access jacket portion that are connected together by a continuous transition that is applied during cable manufacturing. Thus, the craftsman may conveniently access the at least one tether optical fiber for distribution into the optical network.

  • Publication number: 20090034923
    Abstract: Fiber optic drop cables are disclosed that are suitable for automated preconnectorization. In one embodiment, an optical waveguide is disposed in a buffer tube that has two strength components disposed on opposite sides thereof and a plurality of strength members. The plurality of strength members are disposed at a plurality respective interstices located between the buffer tube and the two strength components and shaped into a plurality of substantially triangular shapes for improving the balancing of the residual stresses in the fiber optic cable caused by the shrinkage of a cable jacket during cooling. In another embodiment, a fiber optic cable includes a tonable lobe connected by a web that is frangible and the web includes predetermined ratios for easily and reliable separation of the tonable lobe.

  • Patent number: 7308175
    Abstract: A buffered optical fiber includes at least one optical fiber and a buffer layer. In one embodiment, the buffer layer generally surrounds the optical fiber and has a non-round cross-section that includes a plurality of wings that are an integrally formed by the buffer layer. Additionally, the buffered optical fiber may form a portion of a fiber optic cable that allows a relatively small bend radius while maintaining optical performance. Optionally, the optical fiber may be a bend resistant optical fiber for preserving optical performance. Additionally, other fiber optic cables that allow relatively small bend radii are also disclosed.

  • Patent number: 6937801
    Abstract: A fiber optic cable is provided that includes a plurality of lengthwise extending, non-jacketed bundles of optical fibers and a cable jacket surrounding the bundles of optical fibers. Each bundle of optical fibers may include a binder, such as a binder thread, for maintaining the integrity of the bundle. The binder may include, for example, a binder thread formed of an air entangled, textured, continuous multi-filament thread. The fiber optic cable may also include a separation element for preventing adhesion between the bundles of optical fibers and the cable jacket without having to separately jacket each bundle of optical fibers.
