Abstract
An inner, optical fiber core clamping ferrule has an optical fiber clamping portion for receipt in an outer ferrule and defining an axially extending through-passageway, an axial slit extending through the clamping portion divides the passageway into two opposed groove portions receiving a prepared end of an optical fiber extending along the through-passageway. The inner ferrule is force-fitted in the outer ferrule to extend co-axially therewith, with wall portions thereof maintaining the opposed walls of the spaced apart slit in open condition so that opposed walls of the groove portions are pressed into gripping engagement with the optical fiber. The opposed walls of the slit diverge as they extend radially outwardly away from the groove portions. The inner ferrule may be split for the entire length of the through passageway forming two halve hinged together at one end or have open slits formed in an otherwise imperforate tubular wall.
