An optical connector mainly includes a base and a mount. The base has a first slot. The base has a receiving space for arranging the optical component. The mount has an adapting end inserted into the first slot. A connecting port is formed on the adapting end. The base is connected with an external wire through the connecting port. The adapting end has an opening corresponding to the position of a tunnel of the base. Thus, when the external wire is inserted into the connecting port, the optical component can receive an optical signal from the external wire through the tunnel of the base and the opening on the mount.
