摘要： 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. Thereafter, the tool is removed and the cut distribution optical fiber is routed through the opening at the access location so the distribution optical fiber is presented outside the protective covering.

摘要： A fiber optic cable assembly with a floating tap is disclosed, wherein the assembly comprises a fiber optic cable having a cable fiber assembly, such as in the form of a ribbon stack. The assembly includes at least one network access point (NAP) for accessing at least one cable fiber in the cable fiber assembly and at least one strength area for example a strength member. At least one cable fiber is extracted from the cable fiber assembly and held by a transition assembly. A buffer conduit loosely contains the at least one cable fiber and guides it to an intermediate buffer conduit, which in turn guides the at least one cable fiber to a splice tube. The intermediate buffer conduit can translate relative to the splice tube. At least one tether fiber is spliced to the at least one cable fiber. Alternatively, the at least one cable fiber has sufficient length to serve as the at least one tether fiber so that splicing to another fiber is not required. Each strength member is covered by a movable member. A bonding structure bonds the cable fiber assembly, buffer conduit and movable member so that the cable fiber assembly can translate but not rotate relative to the cable within the NAP. This allows the tap point to “float” within the NAP when the cable fiber assembly needs to translate within the cable.

摘要： 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.

摘要： Angular alignment of optical fibers for fiber optic ribbon cables and related methods are disclosed. Employing optical fibers disposed in a ribbon matrix can increase bandwidth between two interconnection points. In one embodiment, optical fibers are angularly aligned during the process of forming a fiber optic ribbon cable. To angularly align the optical fibers, each of the optical fibers include an angular alignment feature to facilitate uniform or substantially uniform angular orientation along a cable when the optical fibers are prepared to be disposed in the ribbon matrix to form a fiber optic ribbon cable. By purposefully aligning the optical fibers during formation of the fiber optic ribbon cable, end portions of the optical fibers are aligned in the ribbon matrix. Thus, end portions of the ribbon matrix are not required to be removed to expose and align the end portions of optical fibers when the ribbon cable is connectorized.
