A universal optical fiber plug includes a body, a neck formed on the body, a tube extending out from the neck and an annular sealing ring formed on the neck near the joint with the tube to correspond to the recesses in the socket. A blank plug has a blank plug body, a blank plug neck formed on the blank plug body, a blank plug tube extending out from the blank plug neck, and a sealing ring extending out radially from the blank plug neck. A cap is further formed at a joint of the blank plug body and the blank plug neck to prevent contamination of the filament inside the socket.
