ABSTRACT:
This invention relates to a ferrule for use in a fiber optic connector. The ferrule has front and rear faces and comprises (a) a passage being disposed inside the ferrule and having first and second ends, the passage having dimensions defined by the following formulas:in-line-formulae description="In-line Formulae" end="lead"?(n*a)≦H≦(n+1)*ain-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?X≦W≦X+bin-line-formulae description="In-line Formulae" end="tail"?where “W” is the passage width, “H” is the passage height, “X” is the measured with of a fiber optic ribbon, “n” is the number of fiber optic ribbons and n>1, “a” is the fiber optic ribbon thickness and “b” is the fiber pitch on a (b) a plurality of tapered channels disposed between the second end of the passage to said front face of the ferrule.
