摘要
以太网供电(POE)技术是一项新兴的具有广阔发展和实用前景的技术,该技术允许供电设备(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)提供一定功率的直流电。基于该供电技术的基本原理、接入方法,阐述了以太网供电系统的结构和特点及在实际案例中的应用,并对该供电技术的发展和应用前景作了描述。
The POE technology also known as the power supply equipment （PSE） provides power as well as data over an Ethernet cables to the power device （PD）. It＇s a new introduced technology at recent years which has quite wildly future development and good practicality. This article describes the technology＇s work principle and method of set up by providing some typical installation, also some information about the future area of development and exertion.
