A fiber optic cable connector for an optical ribbon comprises a multi-fiber ferrule having a plurality of stub fibers secured therein with ends of the fibers projecting beyond the end of the ferrule. The connector also includes first and second opposed splice members extending lengthwise from a first end proximate the end of the ferrule to an opposite second end, and the ends of the stub fibers extend between the opposed splice members at the first end thereof and are disposed in fiber-aligning grooves formed in the first splice member. The splice members are arranged with a fiber-receiving space therebetween to allow the optical fibers of the fiber optic ribbon to be inserted through the fiber-receiving space such that the optical fibers engage the grooves and are guided by the grooves into optically connected relation with the ends of the stub fibers. The connector further includes a cam movable between an initial position allowing the splice members to move apart to enlarge the fiber-receiving space to facilitate insertion of the optical fibers therein, and a final position in which the cam urges the splice members in the vicinity of the ends of the stub fibers toward each other to clamp the ribbon fibers therebetween. The rear end portion of the second splice member can pivot away from the first splice member to facilitate inserting the ribbon into the connector. A tool for installing the connector in the ribbon is also disclosed.

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.

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.

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.

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.

An adapter is provided for operatively mating two optical fiber connectors of the type that are aligned relative to each other by guide pins. The adapter has two sleeve body halves that are joined together at a mating ends. A guide pin mount is captured between the two sleeve body halves that defines an opening to allow abutment of the two connectors therethrough. Two guide pins mounted on the guide pin mount parallel with the passageway defined through the sleeve and located so as to engage the guide pin holes on the connectors and align two connectors inserted into the adapter.
摘要:
The fiber optic interconnection apparatus includes a receptacle mounted at least partially within a wall of an enclosure, such as an optical network unit, a network interface device or a splice closure, and a fiber optic cable assembly for mating with the receptacle. By mating the fiber optic cable assembly with the receptacle in a predetermined aligned manner, one or more optical fibers of the fiber optic cable on which the fiber optic cable assembly is mounted can be optically interconnected with respective optical fibers held by the receptacle which extend through the receptacle and into the enclosure. Since the optical fibers which extend through the receptacle and into the enclosure may have been previously terminated, such as during the initial configuration of the enclosure in which the optical fibers are spliced or otherwise connected to other optical fibers or to active equipment within the enclosure, the fiber optic interconnection apparatus permits the optical fibers of the fiber optic cable to be appropriately terminated within the enclosure without requiring the enclosure to be opened. The components within the enclosure are therefore protected from damage which might otherwise result from opening the enclosure to terminate the optical fibers.
