A connecting module included in a power over network device includes a pair of capacitors and a power transformer that interconnects the capacitors. The power over network device is to be connected to one of a power source equipment (PSE) and a powered device (PD). When connected to the PSE, the capacitors receive a network signal, the power transformer receives the network signal and a direct current power signal for generating a power line signal. When connected to the PD, the power transformer receives the power line signal, extracts a direct current power signal from the power line signal, and the capacitors of the connecting module receives the network signal, and blocks a direct current component of the remainder of the power line signal. |

1. A power over network device comprising at least one connecting module, said connecting module including a pair of capacitors and a power transformer that interconnects the capacitors,
wherein said power over network device is operable to be electrically connected to one of a power source equipment and a powered device; wherein when said power over network device is electrically connected to the power source equipment,
said capacitors of said connecting module are disposed to receive a network signal, andsaid power transformer of said connecting module is disposed to receive the network signal and a direct current power signal, and to generate, by combining the network signal and the direct current power signal, a power line signal which is to be transmitted to the powered device; and wherein when said power over network device is electrically connected to the powered device,
said power transformer of said connecting module is disposed to receive a power line signal from the power source equipment, and to extract a direct current power signal from the power line signal for the powered device, the remainder of the power line signal after the direct current power signal has been extracted serving as a network signal, andsaid capacitors of said connecting module is disposed to receive the network signal, and to block a direct current component of the network signal. |
