摘要： A method and apparatus precisely determines the orientation of the axis of a guide pin hole defined by a multifiber ferrule, and therefrom, precisely determines an end face angle of the ferrule without reference to external features of the ferrule. A measurement pin is positioned in the guide pin hole with a first end disposed proximate the end face of the ferrule. A reference plane defined by the first end of the measurement pin is measured. The orientation of the axis of the guide pin hole is determined based upon the predetermined angle between the axis of the guide pin hole and the reference plane. A plane defined by at least a portion of the end face of the ferrule is then measured. The end face angle is precisely determined based upon the angular difference between the reference plane and the plane defined by the end face of the ferrule.

摘要： A guide block assembly for aligning and retaining fiber bore forming pins and guide pin bore forming pins in precise relation to each other during the molding of a multi-fiber ferrule includes a unitary member defining at least one fiber bore and at least one guide pin bore. Each fiber bore, and optionally each guide pin bore, is formed by creating a starter hole using a first electric discharge machining (EDM) wire and enlarging the starter hole using a second EDM wire. Each fiber bore has a length to diameter ratio of between approximately 3:1 to 10:1, more preferably between approximately 4:1 to 8:1, and most preferably approximately 6:1. The guide block assembly may further include a cavity behind the fiber bore and a front face that forms a non-rectilinear surface on the face of the ferrule. The unitary block assembly contains fewer parts and is less expensive to manufacture.

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： An alignment sleeve for precisely aligning a pair of ferrules, such as a pair of multifiber ferrules, is provided along with an associated assembly method. The alignment sleeve includes a sleeve member defining a lengthwise extending cavity opening through opposed ends thereof. The sleeve member can also define at least one window and, more commonly, a plurality of windows opening into the cavity. The alignment sleeve also includes a guide pin extending lengthwise through the cavity and a guide pin engagement member extending at least partially into the window defined by the sleeve member. The guide pin engagement member is bonded, such as by welding, to the guide pin such that the guide pin is retained in a floating relationship within the sleeve member. The sleeve member can also define an expansion window to accommodate expansion of the guide pin that is creating during welding of the guide pin. By retaining the guide pins in a floating relationship within the sleeve member, the alignment sleeve aligns the ferrules with increased precision since the precision of the alignment is dictated, not by the precision with which the alignment sleeve is fabricated, but by the precision with which the closely toleranced ferrules are formed.
摘要翻译：提供用于精确对准一对套圈（例如一对多光纤套圈）的对准套筒以及相关联的组装方法。对准套筒包括套筒构件，该套筒构件限定通过其相对端部开口的纵向延伸空腔。套筒构件还可以限定至少一个窗口，更通常地，限定通向空腔的多个窗口。对准套筒还包括纵向延伸通过空腔的引导销和至少部分延伸到由套筒构件限定的窗口中的引导销接合构件。引导销接合构件例如通过焊接结合到引导销，使得引导销在套筒构件内以浮动关系保持。套筒构件还可以限定膨胀窗口以适应在引导件的焊接过程中产生的引导销的膨胀。通过将引导销保持在套筒构件内的浮动关系中，由于对准的精度不是通过制造对准套筒的精度而是由对准套筒的精度决定，所以对准套筒以更高的精度对准套圈，形成紧密公差的套圈。
