ABSTRACT:
An optical fiber connector assembly using eccentric ferrule centering means for adjusting the concentricity of the optical fiber interface end with respect to the connector body perimeter. The eccentric ferrule or ferrules are in the form of elongated sleeves with the innermost sleeve extending from the connector body end the greatest amount. An external crimp sleeve of a relatively soft malleable metal has a generally conical shape with internal step-tapered diameter to fit over the eccentric ferrule exposed ends. Once the concentricity alignment of the optical core has been effected by relative rotation of the eccentric ferrule members (sleeves), crimping of the soft metal sleeve to each eccentric sleeve exposed extremity fixes the relative rotational position of these ferrules preserving the concentric alignment of the optical fiber in the connector body.
