SPoE stands for "Single Pair Power over Ethernet", which is a technology that allows both power and data to be transmitted over a single twisted-pair cable.
A PoE transformer is used to convert the Ethernet data and power signals to a level that can be used by the network device. The transformer is responsible for isolating the data and power signals from each other, as well as providing the necessary voltage levels to power the device.
The SPoE transformer is a type of PoE transformer that is designed to work with single-pair Ethernet cables. This technology is often used in applications where only a small amount of power is needed, such as in IoT devices, sensors, and LED lighting.
Compared to traditional PoE, SPoE has several advantages, such as lower cost, longer range, and lower power consumption. However, it also has some limitations, such as lower power delivery and limited compatibility with existing Ethernet infrastructure.
Overall, SPoE is a promising technology that has the potential to revolutionize the way we power and connect devices in the Internet of Things (IoT) era.
