ABSTRACT:
An adapter assembly is provided for removably receiving two optical fiber ferrules of the type with open grooves extending longitudinally rearward of the end face of the ferrule. The assembly comprises a sleeve with an interior surface that defines a passageway therethrough sized for receiving the ends of the ferrules therein. The interior surface also defines two longitudinal grooves opposite each other that open to the passageway. A guide pin is located in each groove such that an exposed portion of the outer surface of the guide pin along the entire length of the guide pin inside the sleeve is exposed to the passageway. The exposed portion are sized and located relative to each other to slide in the ferrule grooves and operatively align the end faces of the ferrules rotationally and laterally relative to each other when the two ferrules are inserted into the sleeve.
