摘要： A ferrule and an associated fabrication method are provided that facilitates fiber-to-fiber contact without requiring the end portions of the optical fibers to protrude beyond the front face of the ferrule. The ferrule includes a ferrule body having opposed front and rear faces and defining at least one optical fiber bore extending between the front and rear faces and adapted to receive an optical fiber. Advantageously, at least the medial portion of the front face through which the optical fiber bores open protrudes outwardly beyond at least some peripheral portions of the front face. By designing the front face such that the medial portion protrudes outwardly beyond peripheral portions of the front face, angular errors in the peripheral portions of the front face and dirt or other particles that accumulate on the peripheral portions of the front face will not prevent the medial portions of the front faces of a pair of ferrules from making contacting as the respective fiber optic connectors are mated. As such, the end portions of the optical fibers need not protrude much, if any, beyond the front face of the ferrule in order to establish fiber-to-fiber contact such that the ferrule can absorb at least some of the forces that would otherwise be imparted to the optical fibers.
摘要翻译：提供一种套圈和相关联的制造方法，其有助于光纤到纤维接触，而不需要光纤的端部突出超出套圈的前表面。套圈包括具有相对的前后表面并且限定在前后表面之间延伸并适于接收光纤的至少一个光纤孔的套圈体。有利地，至少光纤孔打开的正面的中间部分向外突出超出正面的至少一些周边部分。通过设计正面使得内侧部分向外突出超过正面的周边部分，正面的周边部分和积聚在前表面的周边部分上的污垢或其他颗粒的角度误差将不会妨碍内侧一对套圈的前表面的一部分作为相应的光纤连接器接合而配合。因此，光纤的端部不需要突出超过套圈前表面的许多（如果有的话），以便建立纤维与纤维的接触，使得套圈可以吸收至少一些其他的力赋予光纤。

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.

摘要： An adjustable tether assembly for a fiber optic distribution cable includes a tether cable and an overmolded housing secured at the end of the tether cable having at least one connector port. The tether assembly is attached to the distribution cable such that the position of the connector port is adjustable along the length of the distribution cable for mitigating differences between the pre-engineered span length distance and the actual span length distance following installation of the distribution cable. A method for mitigating a span length measurement difference in a pre-engineered fiber optic communications network is provided that includes optically connecting an adjustable tether assembly at a mid-span access location of a fiber optic distribution cable and positioning a housing secured at the free end of a tether cable having at least one connector port at a desired location in the network to compensate for the span length measurement difference.

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 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.

摘要翻译：提供了一种预组装的多光纤连接器，其包括连接器壳体和在横截面上基本上为矩形的无窗多芯线圈。无窗多芯线圈可以至少部分地设置在由连接器壳体限定的内部空腔内，从而形成不具有光纤的多纤维连接器。因此，在将多根光纤插入由无窗多光纤套圈限定的光纤孔之前，多纤连接器能够被预先组装。因此，根据本发明也提供了预组装多纤连接器的相应方法。还提供了能够从无窗构造选择性地转换为窗口构造的套圈。该实施例的套管包括不仅限定至少一个光纤孔的套管主体，而且还限定了穿过套圈主体的侧表面的阱。套圈主体还包括至少部分地覆盖井的可移除的网，从而限定套圈的无窗构造。纸幅能够从井中选择性地移除，使得未覆盖的井通过穿过至少一个光纤孔的套圈的侧表面形成窗口，从而限定套圈的窗口构造。
