摘要： Devices and methods are described that permit simple correction of a fiber optic polarity reversal problem. An adapter is described having receptacles to receive a connector on a first end, or user end, and on a second end, or contractor end. Both the receptacles provide keying arrangements so that the connectors can be received only when correctly oriented with respect to the adapter. The keying arrangement on the contractor end, however, is reversable so that the connector may be inserted in one of two predetermined orientations, at the behest of the contractor or installer. Adapters are also described that receive connectors only in a physically reversed orientation to counteract a reverse polarity condition. In addition, a jumper is described that can be interposed between a connector and adapter to correct a reverse polarity condition.

摘要： Methods are provided for validating the continuity of one or more optical fibers upon which a fiber optic connector is mounted. Typically, the fiber optic connector is mounted upon an optical field fiber by actuating a cam mechanism to secure the optical field fiber in position relative to an optical fiber stub. If subsequent testing indicates that the continuity of the optical field fiber and the optical fiber stub is unacceptable, the cam mechanism can be deactuated, the optical field fiber can be repositioned and the cam mechanism can be reactuated without having to remove and replace the fiber optic connector. In order to determine if continuity has been established between the optical field fibers and respective optical fiber stubs, a method is also provided that introduces light into at least one of each pair of optical field fibers and optical fiber stubs and that only secures the position of each optical field fiber relative to the respective optical fiber stub once the glow associated with each pair of optical field fibers and optical fiber stubs dissipates, which dissipation indicates the establishment of continuity. An improved multifiber connector and installation tool are also provided to facilitate the establishment and validation of the continuity of optical field fibers and optical fiber stubs in order to reduce the time and cost required to connectorize optical field fibers in the field.

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： 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.
