A transceiver includes a lead-frame, a signal emitter, a signal receiver, and a coupling lens. The signal emitter and the signal receiver are attached on a same pad of the lead-frame. The coupling lens covers the signal emitter and the signal receiver. Since the positions of the signal emitter and the signal receiver are adjacent to each other, the coupling lens can be used to couple the signal emitter and the signal receiver for transmitting and receiving signals.
