A small form-factor pluggable transceiver is coupled to a cable connector and a network device. The small form-factor pluggable transceiver includes a first connection port, a conversion unit, a transceiver unit, and a second connection port. The conversion unit includes a bandwidth indication pin, and the transceiver unit includes a detection pin. The transceiver unit operates in a normal state based on providing a first voltage level by the detection pin, and operates in an abnormal state based on providing the second voltage level by the detection pin. The bandwidth indication pin indicates that a signal source received by the first connection port is a copper cable-type signal source, and indicates that a rate of the signal source is an invalid rate. The detection pin provides the first voltage level based on the invalid rated by being coupled to a ground point.
