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。

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.
摘要翻译：提供了性别可选择的光纤连接器，其可以在连接器的组装和抛光之后容易地在阳和阴配置之间转换。性别可选择的光纤连接器包括壳体，可操作地连接到壳体的套圈，使得套圈的前部延伸超过壳体，以及适于安装在套圈的前部上的罩，套圈延伸穿过由护罩限定的通道。为了改变光纤连接器的性能，护罩具有阳和阴配置。在这方面，护罩的阳型结构包括至少一个引导销，纵向延伸穿过由护罩限定的通道，用于接合由套圈限定的纵向延伸的对准槽，以便产生阳光纤连接器。相比之下，护罩的阴构造没有引导销，使得将护罩的阴构造安装在套圈上产生阴光纤连接器。除了性别可选择的光纤连接器和相关的护罩之外，还提供了一种制造性别可选光纤连接器的方法。此外，还提供出口组件用于接收具有横截面的矩形形状的光纤连接器，例如MT连接器或具有矩形形状的护罩的性别可选择的光纤连接器，并且用于精确地对准矩形截面，具有基本上圆柱形的套圈，例如DC或QC套圈，以增加不同类型的套圈可互连的柔性，以及所得互连的精度。

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.
摘要翻译：提供一种多光纤套圈，其包括套圈本体，其限定穿过套圈本体的前表面的至少一个细长孔，该细长孔又包括靠近前表面的引入部分，用于将相应的对准构件引导到细长的孔。套圈主体至少部分地限定一个或多个细长孔，例如引导销孔或对准槽，每个具有延伸穿过其中的纵向轴线。每个细长孔包括靠近前表面的引入部分和相邻的对准部分。引导部分在从相邻的对准部分延伸到套圈主体的前表面的方向上从纵向轴线径向向外扩展。因此，引导部分穿过套圈主体的前表面的横截面比通向相邻对齐部分的导入部分的开口大。因此，引入部分能够将相应的对准部件引导到相邻的对准部分中，该相应的对准部分又被调整为紧密地接纳对准部件，从而用于使套圈与对准部件正确对准。此外，由多光纤套圈限定的每个细长孔的引入部分用作用于污垢或其它微粒的容器，当对准构件插入到相应的细长孔中时，其从对准构件传送。

摘要： A ferrule is provided that defines a shoulder having curved corners. In this regard, the ferrule includes a lengthwise extending shaft and an enlarged rear portion proximate the shaft. The rear portion is larger in lateral cross-section than the shaft to thereby define a shoulder. In addition, that portion of the shaft proximate the enlarged rear portion includes curved corners such that the shoulder has corresponding curved inner corners. A fiber optic connector housing is also provided that defines an inwardly projecting shoulder having curved corners. The fiber optic connector housing includes a forward segment defining a lengthwise extending passage and a rearward segment also defining a lengthwise extending passage. The lengthwise extending passage defined by the rearward segment is larger in lateral cross-section than the lengthwise extending passage defined by the forward segment such that a shoulder is defined at the intersection of the forward and rearward segments. In addition, that portion of the forward segment proximate the rearward segment defines a section of the lengthwise extending passage having curved corners such that the resulting shoulder also has curved corners. By including shoulders having curved corners, the fiber optic connector of the present invention allows the ferrule to float within the internal cavity defined by the connector housing without becoming dislodged and assuming a cocked position within the internal cavity.

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.
