Abstract
Abstract A fiber optic connector which includes a connector body having at least one socket cavity therein and a socket contact inserted into the socket contact cavity. The socket contact has a retention area and a cable termination area at one end and a retractable contact portion at the other end. The connector further includes means on the retractable contact portion for limiting axial movement of the contact portion so that when the contact portion is unretracted, a tip of the contact portion is substantially flush with a surface of the connector body.
