An optical connector has a base, the base includes a least one first slot thereon, and the base further includes at least one optical component, a circuit board, a signal transforming integrated circuit (IC), and a plurality of connecting terminals therein. The circuit board electrically connects to the optical component, the signal transforming IC, and the connecting terminals. The first slot is used to connect with an external wire, an optical receiving portion of the optical component receives optical signal which is sent from the wire, and the received optical signal is sent to the signal transforming IC to transform the optical signal into electronic signal. Finally, optical connector sends the transformed electronic signal externally through the connecting terminals. Therefore, optical signal transmission facilitates the optical connector to upgrade transmitting rate, and compatibility of the optical connector can be ensured by transforming the optical signal into electronic signal.
