  • Publication number: 20080152293
    Abstract: The present invention provides a cable assembly comprising a flexible network access point that includes a flexible cover over a mid-span access location, providing environmental protection for the mid-span access location and facilitating installation of a distribution cable. Subsequent to installation, the mid-span access location is exposed and accessed by pulling a ripcord, for example, thereby removing a portion of the flexible cover. This exposes one or more connectors, which may be single or multi-fiber connectors, that are configured to receive the receptacles of one or more drop cables and/or tethers. Thus, a semi-hardened, selectively-usable closure is provided.

  • Publication number: 20080019641
    Abstract: A pre-connectorized fiber optic distribution cable assembly includes a plurality of optical fibers and at least one mid-span access location along the length of the distribution cable. At least one of the optical fibers is accessed, terminated and then connectorized at the mid-span access location to an optical connector disposed within a receptacle. The mid-span access location, the accessed, terminated and connectorized optical fiber, the optical connector and at least a portion of the receptacle are encapsulated with a protective overmolded shell. A tether including at least one optical fiber connectorized at a first end of the tether is optically connected to the optical connector through the receptacle. A second end of the tether opposite the first end terminates in a network optical connection terminal, thereby compensating for a span length measurement difference between the actual location of the mid-span access and the desired location of the optical connection terminal.

  • Patent number: 7228036
    Abstract: An adjustable tether assembly for a fiber optic distribution cable includes a tether cable and an overmolded housing secured at the end of the tether cable having at least one connector port. The tether assembly is attached to the distribution cable such that the position of the connector port is adjustable along the length of the distribution cable for mitigating differences between the pre-engineered span length distance and the actual span length distance following installation of the distribution cable. A method for mitigating a span length measurement difference in a pre-engineered fiber optic communications network is provided that includes optically connecting an adjustable tether assembly at a mid-span access location of a fiber optic distribution cable and positioning a housing secured at the free end of a tether cable having at least one connector port at a desired location in the network to compensate for the span length measurement difference.

  • Patent number: 7209375
    Abstract: Eccentricity of a optical fiber installed in a passageway of a ferrule is minimized by imposing a force on the end of the optical fiber projecting from the passageway at the ferrule end face to push the optical fiber to a desired position in the passageway, prior to curing an adhesive used for fixing the optical fiber in the passageway, so as to compensate for eccentricity of the passageway. In one embodiment, the force is imposed on the optical fiber by hanging a weight on the optical fiber. In another embodiment, the force is imposed on the optical fiber by using a pressurized jet of fluid. The point of application of the force, the magnitude of the force, and the viscosity of the adhesive are selected such that minimal optical fiber bending occurs, thereby assuring that the optical fiber is positioned at the desired position in the passageway for an appreciable distance from the ferrule end face along the passageway.
