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 right-angle optical-fiber connector assembly for providing an optical connection to an external device such as a circuit board. The connector assembly includes a rigid ferrule having at least one right-angle bend and that defines an interior region and first and second ferrule ends, and a maximum optical fiber bending radius RMAX. One or more bend-performance optical fibers traverse the interior region. Each optical fiber has an associated minimum bending radius RMIN and includes a bending radius RF such that RMIN≦RF≦RMAX, wherein at least one of the one or more optical fibers has RF=RMIN. The first and second connector ends are respectively located at or near the first and second ferrule ends and operably support the first and second optical fiber ends. The connector ends are each adapted to provide an external optical interconnection to an external device such as a circuit board.
