Abstract: The fiber optic interconnection enclosure, such as a fiber optic distribution frame or the like, effectively limits the entry of particles, such as dust and other contaminants, into the enclosure. For example, the fiber optic interconnection enclosure can maintain a greater pressure, i.e., a positive pressure, within the internal cavity defined by the enclosure than outside of the internal cavity so as to effectively limit the entry of particles into the internal cavity, even as the door of the fiber optic interconnection enclosure is repeatedly opened and closed. The fiber optic interconnection enclosure generally includes at least one fan to draw air into the internal cavity through an air inlet port defined by the cabinet and to circulate the air through the internal cavity in order to reduce the number of particles that settle upon or are transferred to the end faces of the optical fibers or other surfaces within the internal cavity.

Abstract: The fiber optic connector includes a crimp body defining a longitudinal bore extending between the first and second opposed ends of the crimp body. The fiber optic connector also includes a cylindrical shroud defining an internal bore in which a ferrule assembly is disposed. The internal bore extends longitudinally between the first and second opposed ends of the shroud. The first end of the shroud is connected to the second end of the crimp body such that the internal bore of the shroud opens into the longitudinal bore of the crimp body. The crimp body is preferably formed of a metal, while the shroud is preferably formed of a plastic material such that the first end of the shroud can be ultrasonically welded to the second end of the crimp body. In order to further secure the crimp body and the shroud, the second end of the crimp body can include a lip that extends radially outward to engage the first end of the shroud.

Abstract: A composition that includes a hydrated inorganic filler and a polymer blend is disclosed. The polymer blend includes a polymerization or copolymerization product of one or more ethylenically unsaturated monomers. In addition, the polymer blend includes an aliphatic polyketone. The incorporation of aliphatic polyketone with polyethylene based polymers or copolymers results in dramatic improvements in both drip resistance and char strength; moreover, the composition of the present invention can use reduced amounts of hydrated inorganic filler relative to conventional polyethylene based compositions. This reduction in the amount of hydrated filler is expected to lead to improvements in physical properties and extrudability not otherwise possible. These properties make the compositions of the present invention particularly useful as an outer layer for electrical wires, optical fibers, or cables containing at least one wire, optical fiber, or both.

Abstract: The present invention provides a splitter module with an xDSL splitter circuit that is removably installable in a network interface device (NID) and interconnectable with a POTS module in the NID to split the POTS and xDSL signal onto separate inside wire pairs terminated in the NID. The splitter module has a jack and a plug. The plug from the POTS module is inserted in the jack on the splitter module and the plug on the splitter module is then inserted into the jack on the POTS module. This exchange of plugs and jacks place a splitter circuit between the outside plant wiring and the pairs of inside wiring.

Abstract: A weatherproof protector module for telecommunication circuits has wire insertion points that are arranged in lateral, forward and rearward symmetry about a single stuffer screw. The module contains J-shaped insulation displacement connectors (IDCs) with slits for engaging the wires. The symmetry of the module allows the screw to exert balanced forces in every direction as the wires engage the IDCs. The module also contains an insulative gel that is extruded around the wire contact locations when the wires are engaged. A wiper seal located each wire insertion point and a thixotropic gel prevent the expulsion of the insulative gel from the module after extrusion.

Abstract: The optical fiber interconnection closure includes a housing defining an internal cavity and a fiber management frame disposed within the internal cavity. The fiber management frame includes a plurality of partitions for dividing the internal cavity into at least one and, more commonly, a plurality of slack storage compartments and a fiber interconnection compartment. The slack storage compartments are adapted to store slack lengths of optical fiber, while the fiber interconnection compartment is adapted to receive end portions of the optical fibers from the slack storage compartment such that the optical fibers can be interconnected therein. More particularly, one slack storage compartment can store slack lengths of unspliced express optical fibers, while another slack storage compartment can store slack lengths of the optical fibers that are spliced within the closure.

Abstract: A fiber optic connector cabinet is provided that has at least one adapter panel rotatably mounted to the cabinet and that carries at least one fiber optic connector adapter. The angular position of the adapters relative to a front plane of the cabinet is readily adjustable.

Abstract: A fiber optic cable (10) includes a cable core (20) and a jacket section (30). Cable core (20) includes a central member (21), buffer tubes (23, 26), and optical fibers (22, 25) in respective buffer tubes. Jacket section (30) includes a tape layer (34) with a seam (35), and a seam guard (40) disposed over seam (35). Seam guard (40) is operative to perform dual functions, as the seam guard includes substrate (42) operative to prevent cable zippering, and a waterblocker (44) operative to inhibit the migration of moisture into cable core (20).
