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 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.

摘要： A fiber optic connector includes a multifiber ferrule and at least one force centering element for applying a biasing force to the ferrule in the longitudinal direction without introducing a moment about a lateral axis. The connector further includes a coil spring for exerting the biasing force and a spring seat disposed between the coil spring and the ferrule. The rearward portion or the forward portion of the spring seat may be provided with a pair of outwardly extending protrusions that are laterally spaced apart to transfer the biasing force to the ferrule. Alternatively, the forward portion of the spring seat or the rear face of the ferrule may define a convex surface. Alternatively, the ferrule defines a convex surface in the direction of a first lateral axis and the spring seat defines a convex surface in the direction of a second lateral axis perpendicular to the first lateral axis.
