摘要： Overmolded ferrule assemblies and methods for making the same are disclosed. Some embodiments include positioning a first plurality of fibers in an alignment fixture in a predetermined arrangement such that a predetermined length of the first plurality of fibers extends beyond an end of the alignment fixture. Similarly, some embodiments include positioning a cover portion of the alignment fixture onto the first plurality of fibers, such that corresponding cover recesses on the cover portion align with the corresponding base recesses on the base portion. One method includes the steps of injecting a flowable material into a port on the alignment fixture, waiting a predetermined time for the flowable material to cure, and after the predetermined time, separating the base portion and the cover portion from the first plurality of fibers and the flowable material to create the overmolded ferrule boot.

摘要： Optical fiber interconnection devices, which can take the form of a module, are disclosed that include an array of optical fibers and multi-fiber optical-fiber connectors, for example, two twelve-port connectors or multiples thereof, and three eight-port connectors or multiples thereof. The array of optical fibers is color-coded and is configured to optically interconnect the ports of the two twelve-port connectors to the three eight-port connectors in a manner that preserves transmit and receive polarization. In one embodiment, the interconnection devices provide optical interconnections between twelve-fiber optical connector configurations to eight-fiber optical connector configurations, such as from twelve-fiber line cards to eight-fiber line cards, without having to make structural changes to cabling infrastructure. In one aspect, the optical fiber interconnection devices provide a migration path from duplex optics to parallel optics.

摘要： Molded fiber optic cable furcation assemblies, and related fiber optic components, assemblies, and methods are disclosed. In one embodiment, an end portion of a fiber optic cable with a portion of a cable jacket removed to expose optical fibers and/or a cable strength member(s) therein and thereafter placing the cable into a mold for creating a molded furcation plug about the end portion of the fiber optic cable. The furcation plug may be overmolded about the end portion of the fiber optic cable. The molded furcation plug can be used to pull a fiber optic cable without damaging the optical fiber(s) disposed within the fiber optic cable. The molded furcation plug is advantageous since it manufactured with fewer parts, without epoxy, and/or without a labor intensive process that may be difficult to automate.

摘要： A slack storage receptacle for storing an excess length of a pre-connectorized fiber optic drop cable extending between an optical connection terminal and a network interface device (NID) includes a housing and a storage means disposed within the housing for receiving the drop cable such that the drop cable slack is stored external to the NID. The slack storage receptacle may be secured to an exterior wall of a subscriber premises and the NID mounted thereon. Alternatively, the slack storage receptacle may be positioned around and formed to the NID. Alternatively, the slack storage receptacle may be buried in the ground adjacent the NID. The drop cable slack may be wound onto the storage means after deployment. Alternatively, the slack storage receptacle may be pre-assembled, shipped to the subscriber premises, and the drop cable unwound from the storage means with the drop cable slack remaining wound on the storage means.

摘要： The method and apparatus of the present invention is capable of precisely determining the orientation of the axis of the guide pin hole defined by a multifiber ferrule. Since the axis of the guide pin hole has a direct relationship to the alignment of the optical fibers, the method and apparatus can also precisely determine the end face angle of the ferrule based upon the axis of the guide pin hole without reference to external features of the ferrule. A measurement pin is initially positioned in a guide pin hole such that a first end of the measurement pin is disposed proximate the end face of the ferrule. The reference plane defined by the first end of the measurement pin is then measured, such as by an interferometer. Based upon the reference plane and the predetermined angle between the reference plane and the axis of the guide pin hole, the method and apparatus can precisely determine the orientation of the axis of the guide pin hole. The method and apparatus can also measure a plane defined by at least a portion of the end face of the ferrule, such as a region of interest surrounding the optical fibers. Based upon an angular difference between the reference plane defined by the first end of the measurement pin and the plane defined by the end face of the ferrule, the method and apparatus can then precisely determine at least one end face angle.
