    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: The at least partially flexible connector assembly includes a slack storage tube connected to the first end of a fiber optic cable for loosely storing excess lengths of the optical fibers. The slack storage tube is typically at least partially flexible. By including a flexible slack storage tube, the connector assembly can be readily flexed, such as during installations of the fiber optic cable in which the end portion of the fiber optic cable must be bent relatively sharply. However, the slack storage tube does generally include crush resistance means for supporting the slack storage tube as the connector assembly is flexed such that the longitudinal bore defined by the slack storage tube remains open. The crush resistance means can include a wire helically wound about the slack storage tube. Alternatively, the slack storage tube can be a corrugated tube. The connector assembly also includes a number of ferrules mounted on the end portions of respective optical fibers as well as a ferrule holder for holding the ferrules in respective predetermined positions. In addition, the connector assembly can include a plug connected at a first end to the slack storage tube and having a second end that is adapted to receive and engage the ferrule holder. By disposing the ferrule holder within the second end of the plug, the plug effectively secures the ferrule holder and, in turn, the ferrules to the slack storage tube so as to form the connector assembly.

    摘要: An adapter assembly is provided for removably receiving two optical fiber ferrules of the type with open grooves extending longitudinally rearward of the end face of the ferrule. The assembly comprises a sleeve with an interior surface that defines a passageway therethrough sized for receiving the ends of the ferrules therein. The interior surface also defines two longitudinal grooves opposite each other that open to the passageway. A guide pin is located in each groove such that an exposed portion of the outer surface of the guide pin along the entire length of the guide pin inside the sleeve is exposed to the passageway. The exposed portion are sized and located relative to each other to slide in the ferrule grooves and operatively align the end faces of the ferrules rotationally and laterally relative to each other when the two ferrules are inserted into the sleeve.

    摘要: The challenge of pulling an optical fiber having a connector at its terminal end without incurring damage to the fiber or connector due to excessive pulling or bending is met by introducing a breakaway feature that disconnects the connectorized fiber from the pulling mechanism upon detecting excessive force. The breakaway feature may be positioned at several locations along the pathway connecting the optical fiber and the pulling force. In one embodiment the breakaway feature is disposed on a cover over the connectorized front end of the optical fiber. In other embodiments the breakaway element is inserted along the cord connecting the connectorized optical fiber to the pulling force.

    摘要: A gender selectable fiber optic connector is provided which can be readily converted between male and female configurations following assembly and polishing of the connector. The gender selectable fiber optic connector includes a housing, a ferrule operably connected to the housing such that a forward portion of the ferrule extends beyond the housing, and a shroud adapted to be mounted upon the forward portion of the ferrule such that the forward portion of the ferrule extends through a passageway defined by the shroud. In order to alter the gender of the fiber optic connector, the shroud has both male and female configurations. In this regard, the male configuration of the shroud includes at least one guide pin extending lengthwise through the passageway defined by the shroud for engaging a lengthwise extending alignment groove defined by the ferrule in order to produce a male fiber optic connector. In contrast, the female configuration of the shroud is free of guide pins such that mounting the female configuration of the shroud upon the ferrule produces a female fiber optic connector. In addition to the gender selectable fiber optic connector and the associated shroud, a method of fabricating the gender selectable fiber optic connector is provided. Moreover, an outlet assembly is also provided for receiving a fiber optic connector having a rectangular shape in lateral cross-section, such as an MT connector or the gender selectable fiber optic connector having a rectangularly-shaped shroud, and for precisely aligning the rectangularly-shaped fiber optic connector with a substantially cylindrical ferrule, such as a DC or QC ferrule, so as to increase the flexibility with which different types of ferrules can be interconnected as well as the precision of the resulting interconnection.

    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.
