Embodiment 1

[0030] The present invention contains the Ethernet passive optical network device of the power carrier module, refer to figure 1 As shown, it includes optical transceiver, EPON ONU unit, multi-port Ethernet switching unit, RJ-45 Ethernet port, power carrier module and power cable. Wherein, the optical transceiver completes the mutual conversion between the optical signal and the electrical signal, and can convert the optical signal into an electrical signal, or can convert the electrical signal into an optical signal. The EPON ONU unit converts PON frames into Ethernet frames, or converts Ethernet frames into PON frames and sends them to the optical transceiver. The multi-port Ethernet switching unit switches the Ethernet frames and transmits the Ethernet frames to the power carrier module and other Ethernet ports respectively. The multi-port Ethernet switching unit can also merge the Ethernet frames transmitted by the power carrier module or the RJ-45 Ethernet port. The RJ-...
