Abstract: A COMBO ONU optical module circuit is provided, including a MCU control circuit, a XGSPON ONU circuit, and a GPON ONU circuit. The MCU control circuit includes three control units. The first control unit is configured to determine a transmission channel according to a signal level. The second control unit is configured to switch between a TX_SD_10G signal and a TX_SD_1G signal. The third control unit is configured to supply power to the GPONG ONU circuit using PWR_1G control or the XGSPONG ONU circuit using PWR_10G control. The first control unit is further configured to control the XGSPON ONU circuit and the GPON ONU circuit in an I2C communication mode. Under control of the first control unit, the XGSPON ONU circuit is configured to receive and emit a 10G optical signal, and the GPON ONU circuit is configured to receive and emit a2.5G optical signal.

Abstract: A device integrated with payment function and collection function, includes a smart memory card and an intelligent terminal. The intelligent terminal is adapted to generate a secure transaction management instruction, send the secure transaction management instruction to the smart memory card and notify an execution result of the secure transaction management instruction; to interact with a bank side system via a remote communication network; to interact with user via a user interface; to interact with another device in near field communication mode; to process transaction instruction, generate a secure transaction application instruction and send the secure transaction application instruction to the smart memory card; and to notify an execution result of the secure transaction application instruction. The smart memory card is adapted to execute the safe transaction management instruction and the safe transaction application instruction.
