What is passive poe?

Passive PoE (Power over Ethernet) is a method of supplying power to networked devices over Ethernet cables without the need for a separate power supply. It uses the same cable that is used for data transmission to provide power to devices that support PoE.

Passive PoE devices usually consist of two parts: a PoE injector and a PoE splitter. The PoE injector is used to inject power into the Ethernet cable, while the splitter is used to extract the power from the cable and deliver it to the device.

Passive PoE is typically used in small network installations, such as home or small office networks. It is relatively easy to install and is less expensive than other PoE methods, making it a popular choice for many users. However, it has limitations such as distance and power output.

Overall, passive PoE is a cost-effective and convenient method for delivering power to networked devices, but may not be suitable for larger and more complex network installations.
