1. A ferrule assembly for terminating an optical fiber comprising:

  • an outer ferrule comprising a tubular body wall having front, mating and rear, optical fiber receiving axial ends;

    an inner optical fiber clamping ferrule comprising a tubular body having a front, axial end and a rearwardly extending optical fiber clamping portion for receipt in the outer ferrule and defining an axially extending through-passageway, an axial slit extending through the clamping portion dividing the passageway into two opposed groove portions so that a prepared end of an optical fiber can be located in the groove portions extending along the through-passageway and the inner ferrule subsequently force-fitted within the outer ferrule to extend co-axially therewith, wall portions of the inner ferrule body at opposite axial ends of the slit maintaining axially extending portions of both respective opposed surfaces of the slit spaced apart from each other with the slit in open condition so that opposed walls of the groove portions are pressed into gripping engagement with the optical fiber therein by the receipt of the inner ferrule in the outer ferrule retaining the optical fiber centered accurately in the ferrule assembly.
