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.

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.

A ferrule is provided that includes a ferrule body defining a longitudinally extending groove that can serve as an alignment feature for polishing operations. In this regard, the ferrule body extends longitudinally between opposed front and rear surfaces so that at least the rear surface generally defines a substantially rectangular shape in lateral cross-section. In addition, the ferrule body typically has first and second major sides and first and second minor sides with the first and second major sides being larger than the first and second minor sides. The ferrule body defines the longitudinally extending groove in at least one of the major surfaces. A jig is also provided for engaging the longitudinally extending groove defined by the ferrule body in order to hold the ferrule in an aligned position during polishing operations. In this regard, the jig includes a jig body having an alignment feature for engaging a complimentary alignment feature of the ferrule. The jig also includes a support element capable of engaging another side of the ferrule, wherein at least one of the jig body and the support element is capable of pivoting.

Disclosed are multifiber ferrule assemblies and methods for manufacturing the same. In one embodiment, a finished multifiber ferrule can be provided with a front end having a first front surface that extends beyond a second front surface, thereby inhibiting interaction with a laser beam during processing. A plurality of optical fibers can be fixed within respective optical fiber bores and extend from respective optical fiber bore openings to a position beyond the first front surface. The plurality of optical fibers can be processed by cutting and polishing with a laser beam for providing each optical fiber with a final polished end surface located beyond the first front surface. In further embodiments, an offset structure is positioned with respect to a finished multifiber ferrule after cutting and polishing the optical fibers.

The fiber optic connector includes a crimp body defining a longitudinal bore extending between the first and second opposed ends of the crimp body. The fiber optic connector also includes a cylindrical shroud defining an internal bore in which a ferrule assembly is disposed. The internal bore extends longitudinally between the first and second opposed ends of the shroud. The first end of the shroud is connected to the second end of the crimp body such that the internal bore of the shroud opens into the longitudinal bore of the crimp body. The crimp body is preferably formed of a metal, while the shroud is preferably formed of a plastic material such that the first end of the shroud can be ultrasonically welded to the second end of the crimp body. In order to further secure the crimp body and the shroud, the second end of the crimp body can include a lip that extends radially outward to engage the first end of the shroud. The second end of the crimp body can also include a textured surface, such as a knurled surface, for further engaging the first end of the shroud.

A fiber optic connector assembly and method for venting gas inside in a fiber optic connector sub-assembly. The fiber optic connector assembly includes a connector sub-assembly including a ferrule and a ferrule holder having a passage extending therethrough. A stiffener tube having a tube body disposed about a portion of at least one optical fiber supports insertion of the optical fiber into the ferrule holder passage. The stiffener tube contains at least one opening in its tube body configured to vent gas trapped inside the stiffener tube during assembly. In this manner, the trapped gas does not form a gas pocket in the bonding agent, which could compromise bonding among the optical fiber, stiffener tube, and connector sub-assembly.

Disclosed are optical assemblies such as field-installable connectors having a laser-shaped optical fiber along with methods for laser-shaping the optical fiber. The field-installable connector includes a ferrule having front and rear opposed faces and at least one fiber bore defined longitudinally therethrough, a stub optical fiber having a distal end with a laser-shaped end face is disposed within the at least one fiber bore of the ferrule and extends a predetermined distance beyond the rear face of the ferrule, and an alignment feature operable for aligning the stub optical fiber with the field optical fiber. One method of laser-shaping the optical fiber includes rotating the optical fiber and sweeping a beam of a laser across the optical fiber and then essentially stopping the rotation of the optical fiber and sweeping the beam through the optical fiber to cut the same with a tapered and angled end face. Other methods may include shifting the laser relative to the optical fiber to create a “pencil-tip” end on the optical fiber.
