What’s Reverse Poe Switch

PoE reverse power supply technology is a habitual name. We usually say that the PoE switch supplies power to the network terminal, and the current flows from the PoE switch to the network terminal for forward power supply. Then, the network terminal (client) is used to supply power to the switch. The power supply method that flows from the terminal to the switch is called reverse power supply.

What's Reverse Poe Switch

In PoE forward power supply, the PoE switch is the power supply end of the PSE, and the network terminal is the PD receiving end. In the PoE reverse power supply, the network terminal is the power supply end of the PSE, and the switch is the PD receiving end. Since most of the current network terminals do not support the PSE power supply function, most of the implementation methods of reverse power supply are to add a PSE power supply module on the network terminal side to realize the PSE function of the network terminal.

Reverse PoE power supply switch, namely PD switch. In some installation scenarios such as corridors, wall hangings, and basements, it is difficult to obtain power. The reverse Poe power supply switch cooperates with the PSE (Power Sourcing Equipment) power supply device to supply power to the switch through the network cable, and the switch does not need an external AC power supply. At this time, the switch acts as a PD (Powered Device) powered device. Switch products powered by reverse PoE, including 4 ports, 8 ports, 16 ports, and 24 ports of different specifications, are mainly used in the networking of rural broadband, residential broadband and urban village broadband, helping small operators to solve the difficulty of broadband access construction, difficult to maintain and high cost of electricity.
