ABSTRACT:
A fiber optic ferrule includes a body extending from a first end to a second opposite end, with the body including an axial passage extending between the first and second ends. The axial passage includes a first diameter portion having a diameter of at least 125 microns, and a second diameter portion having a diameter of at least 250 microns and less than a diameter of the buffer, the second diameter portion positioned between the first diameter and the second end. The axial passage further defines a tapered shape at the second end extending inward from the second end to the second diameter portion. A hub holds the ferrule. A method of assembling a terminated fiber optic cable is also provided.
