    摘要: A preassembled multifiber connector is provided that includes a connector housing and a windowless multifiber ferrule that is substantially rectangular in lateral cross-section. The windowless multifiber ferrule can be at least partially disposed within an internal cavity defined by the connector housing to thereby form a multifiber connector that is free of optical fibers. Thus, the multifiber connector is capable of being preassembled prior to inserting the plurality of optical fibers into the optical fiber bores defined by the windowless multifiber ferrule. A corresponding method of preassembling a multifiber connector is therefore also provided according to the present invention. A ferrule is also provided that is capable of being selectively converted from a windowless configuration to a windowed configuration. The ferrule of this embodiment includes a ferrule body that not only defines at least one optical fiber bore, but that also defines a well extending through a side surface of the ferrule body. The ferrule body also includes a removable web at least partially covering the well to thereby define the windowless configuration of the ferrule. The web is capable of being selectively removed from the well such that the uncovered well forms a window through the side surface of the ferrule that opens into the at least one optical fiber bore to thereby define a windowed configuration of the ferrule.

    摘要: A splicing connector and an associated splice mechanism are provided to splice first and second pluralities of optical fibers without buckling the optical fibers. The connector includes a housing and a retainer disposed of at least partially within the housing which defines a channel through which a plurality of optical fibers extend. The connector also includes a clip for securing the optical fibers within the retainer such that the end portions of the optical fibers are exposed through the forward end of the housing in preparation for splicing the optical fibers. Further, the connector includes a spring for urging the retainer and the optical fibers secured within the retainer toward the forward end of the housing, thereby permitting the optical fibers to be spliced without buckling the optical fibers.

    摘要: A multifiber ferrule is provided that includes a ferrule body that defines at least one elongate hole opening through the front face of the ferrule body that, in turn, includes a lead-in portion proximate the front face for guiding the respective alignment member into the elongate hole. The ferrule body at least partially defines one or more elongate holes, such as a guide pin hole or an alignment groove, each having a longitudinal axis extending therethrough. Each elongate hole includes the lead-in portion proximate the front face and an adjacent alignment portion. The lead-in portion expands radially outward from the longitudinal axis in a direction extending from the adjacent alignment portion to the front face of the ferrule body. As such, the opening of the lead-in portion through the front face of the ferrule body is larger in lateral cross-section than the opening of the lead-in portion into the adjacent alignment portion. The lead-in portion is therefore capable of guiding the respective alignment member into the adjacent alignment portion that, in turn, is sized to snugly receive the alignment member, thereby serving to properly align the ferrule with the alignment members. In addition, the lead-in portion of each elongate hole defined by the multifiber ferrule serves as a receptacle for dirt or other particulates that are transferred from the alignment member as the alignment member is inserted into the respective elongate hole.

    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: The receptacle includes a rotatable coupling nut for engaging an externally threaded fiber optic connector assembly or plug which is mounted upon the end portion of a fiber optic cable. As such, the cross-sectional dimensions of the fiber optic connector assembly can be significantly decreased, thereby permitting the fiber optic cable to be pulled through much smaller ducts or passageways. The receptacle also includes a receptacle body adapted to be mounted in a fixed position, such as to a sidewall of an enclosure. The coupling nut cooperably engages the receptacle body such that the coupling nut is free to rotate relative to the receptacle body even though the longitudinal movement of the coupling nut relative to the receptacle body is limited. In this regard, the coupling nut extends through an aperture defined by the receptacle body such that a flange extending radially outward from the rear end of the coupling nut engages the receptacle body to thereby limit longitudinal movement of the coupling nut in a forward direction. The receptacle can also include an inner sleeve extending at least partially through the longitudinally extending bore of the coupling nut. The inner sleeve can include a flanged rear portion connected to the receptacle body rearward of the rear end of the coupling nut to thereby limit longitudinal movement of the coupling nut in a rearward direction.

    摘要: 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.
