  • Patent number: 7693374
    Abstract: Fiber optic distribution cables and methods for manufacturing the same are disclosed. The methods present one or more optical fibers outward of the protective covering for distribution of the same toward the subscriber. Specifically, the methods include presenting a length of distribution optical fiber outward of the protective covering that is longer than the opening at access location. After the opening is made in the protective covering at the access location, the optical fibers for distribution are selected. Then a tool according to the present invention is positioned about the optical fibers selected for distribution and slid within the protective covering of the fiber optic distribution cable until it reaches a cutting location within the fiber optic distribution cable. Consequently, the tool is positioned for cutting the distribution optical fiber at a cutting location within the fiber optic distribution cable at a downstream location.

  • Publication number: 20100040333
    Abstract: A method of assembling an optical fiber connector includes the steps of providing a ferrule with an internal through passage, and using a gas for treating a surface of the internal through passage to enhance a bonding capability of the surface. Adhesive is introduced into at least a portion of the internal through passage and at least one optical fiber is secured to the surface of the internal through passage by the adhesive. Another method includes the steps of providing the ferrule with an internal through passage including a shoulder, a window that extends through a side surface, and a cap having at least a portion inserted into the window. Adhesive is introduced into at least a portion of the internal through passage and is in engagement with the shoulder for providing an axial stop for securing at least one optical fiber with respect to the internal through passage.

  • Patent number: 7628545
    Abstract: A fiber optic plug assembly of a fiber optic connector assembly is provided and generally includes a fiber optic plug mounted upon an end of a fiber optic cable; a pre-molded boot placed over the fiber optic plug and the fiber optic cable; and a crimp band mated over the pre-molded boot to secure the boot to the fiber optic cable; wherein the fiber optic plug assembly is operable to mate to a fiber optic receptacle. The plug assembly eliminates the need for an overmolded boot. Further, the present invention eliminates the need to perform a heat shrink between the buffer tube and crimp body through the internal O-ring. The plug assembly meets the standards of GR-3120-CORE while at the same time providing a simpler hardware package that can be assembled with ordinary connectorization tools.

  • Publication number: 20090297099
    Abstract: A bent optical fiber coupler (100) that employs at least one optical fiber (10) is disclosed. The coupler includes a curved optical fiber guide channel (200) having a strong curve. The optical fiber(s) held within the optical fiber guide channel have a bend corresponding to the guide channel curve. The fiber end portions are optionally disposed within a straight fiber guide (160) at a coupler input/output end, which is preferably configured to have a standard connector geometry. Use of nanostructured fibers for the at least one optical fiber allows for strong bends having tight radii of curvature without imparting significant attenuation. Coupler assemblies that include the coupler optically coupled to at least one opto-electronic device (310) are also disclosed.

  • Patent number: 7596294
    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: 20080175548
    Abstract: A cable assembly configured to be deployed in a fiber optic communications network includes a pulling grip body disposed at an upstream end of the cable assembly and a preconnectorized distribution cable having a plurality of optical fibers and at least one strength member. The pulling grip body includes a pulling loop that is mechanically coupled to the strength member to permit a high tensile load to be transferred to the distribution cable without inducing relative movement between the cable elements. The pulling grip body is preferably formed by overmolding the pulling loop and the strength member with a flexible encapsulant material. At least one multifiber connector is terminated to optical fibers of the distribution cable at the upstream end. The pulling grip assembly and the preconnectorized distribution cable have a low profile capable of being pulled through a conduit.
