Abstract
An optical network device with abnormal light emission detection includes an optical transceiver circuit and a control circuit. The optical transceiver circuit receives a transmission signal. The control circuit enables the optical transceiver circuit according to the transmission signal, so that the optical transceiver circuit outputs an optical signal. The optical transceiver circuit outputs a status signal according to whether or not the optical transceiver circuit outputs the optical signal. The status signal triggers an interrupt system of the control circuit. The interrupt system is provided with a counter to count a light emission duration of the optical transceiver circuit. When the light emission duration is greater than a preset value, the control circuit stops the optical transceiver circuit from outputting the optical signal.
