摘要
以太网供电(POE)技术是指供电设备(PSE)通过一根以太网电缆在传送数据信号的同时向网络受电设备(PD)提供一定功率直流电的技术,是一项新兴的具有广阔发展和实用前景的技术。本文介绍了该供电技术的基本原理、接入方法,以实例形式阐述了实现以太网供电系统的结构和特点,并对该供电技术的发展和应用前景作了描述。
The POE technology is known as that together with data the power supply equipment （PSE） provides power over an Ethernet cables to the power device （PD） in the terminal side. As a new introduced technology at recent years it has quite wildly development future and good practicality. The technolugy＇s work principle and method of set up by providing some typical installation, also some information about the future area of development and exertion are described in this paper.
