ABSTRACT:
A fiber optic connector includes a plug having a ferrule adapted to be connected to a tip end of an optical fiber, a receptacle associated with a light-emitting element and having a ferrule insertion hole defined therein for receiving the plug therein, the ferrule insertion hole being held in light-transmitting communication with the light-emitting element, the receptacle being arranged such that the receptacle establishes an optical path between the light-emitting element and the optical fiber for optical coupling therebetween when the ferrule is inserted into the ferrule insertion hole, and a light blocking element for interrupting the optical path within the ferrule insertion hole in response to insertion of the ferrule into the ferrule insertion hole. The light blocking element comprises a resilient member such as a leaf spring disposed in the ferrule insertion hole and resiliently displaceable into an inner circumferential surface of the ferrule insertion hole when pressed by the ferrule, thereby allowing the ferrule to be inserted into the ferrule insertion hole.
