[0012] In order to more clearly describe the technical content of the present invention, further description is given below in conjunction with specific embodiments.

[0013] The PD test system for receiving and forwarding data below 10G of the present invention includes a PD device bridge, a first 10GPort port, a first 10G PHY chip, a CPU, a second 10G PHY chip and a second 10G Port port. The center tap of the first 10GPort port is connected to the PD device bridge, the first 10G Port port is connected to the first 10G PHY chip, the first 10G PHY chip is connected to the CPU, and the CPU is connected to the second 10G PHY chip.

[0014] As a preferred embodiment of the present invention, the device further comprises an EMC protection circuit, the EMC protection circuit is connected to the PD equipment bridge, and the EMC protection circuit is also connected to the PD equipment.

[0015] As a preferred implementation of the present invention, the center tap of the first 10G Port is connected to a PD device bridge and is connected to the PD device through an EMC protection circuit to supply power to the PD device.

[0016] As a preferred embodiment of the present invention, the first 10G Port receives data, which is forwarded to the second 10G PHY chip through the CPU and connected to the streaming device or other device through the network transformer.

[0017] Most of the 10G ports of PD devices currently in use do not have the function of forwarding data. The conduction test equipment only has two network transformers connected to each other, and a PD load is connected at one end, and no EMC protection is provided for the PD load.

[0018] In a specific embodiment of the present invention, a PD test device for a POE 10G network port, such as Figure 2 As shown, the main functions are as follows:

[0019] The present invention supports the ability of data reception and forwarding, realizes the data forwarding capability of two 10G network ports through two 10G PHY chips and a CPU, realizes the data reception and forwarding functions, reduces the environmental problems caused by the insertion loss of the network port during the test process, and realizes the needs of 10G PSE port 100 meters of flow and connecting PD load.

[0020] The EMC protection function is designed. Ordinary PD loads are generally not designed with EMC protection. Plugging and unplugging PD loads from other ports during use will cause data packet loss and link problems on the 10G port. The present invention adds the EMC protection function based on actual conditions to achieve the ability that the tests between ports do not interfere with each other, and plugging and unplugging other ports will not interfere with the test port.

[0021] The 10G PSE port is connected to the first 10G Port. The power supply is connected to the back-end PD device bridge through the center tap of the first 10G Port and then powers the PD device through the EMC protection circuit. The data part is received by the first 10G Port PHY and forwarded to the second 10G PHY chip through the CPU, and then connected to the streaming device or other equipment through the network transformer.

[0022] The technical solution of the present invention mainly advocates a powered network device supporting data forwarding at a PSE port supporting a 10G rate.

[0023] In the technical solution of the present invention, when the 10G PSE port is connected to port 1, the PSE part supplies power to the PD device, and the data part is forwarded to port 2 through PHY and CPU, and then forwarded to other devices by port 2. At the same time, the EMC protection function is considered in the circuit design.
