Background
In the field of network communication technology, particularly in implementing indoor broadband access, technologies currently in common use include Fiber To The Home (FTTH) and power over ethernet (PoE). These techniques provide an effective solution for data transmission and device powering, but at the same time present some limitations and challenges. For example, FTTH, while providing high-speed internet connectivity, is costly to install and requires additional power supplies to power. PoE technology allows power and data to be transmitted over ethernet cables, simplifying the power supply problem for network devices, but with a limited transmission distance, and the need for power supply increases as the power of the device increases.
Conventional FTTH and FTTB solutions require a large amount of physical wiring and specialized installation, adding to the cost and complexity of network deployment. For network devices requiring power, such as wireless Access Points (APs), traditional approaches rely on power adapters or PoE technology, which, while reducing the need for power cords, are limited to the transmission capabilities and distance of ethernet cords, which may not be sufficient for high power devices. Existing power and data transmission solutions require independent system maintenance, increasing operational costs and complexity, especially in troubleshooting and repair. The power and data lines may introduce electromagnetic interference (EMI) that affects network performance. At the same time PoE systems are at risk of overvoltage and overheat at high loads or incorrect configurations.
