摘要
以太网供电这项创新的技术,通过CAT5/5e/6类非屏蔽双绞线,对网络终端设备既传输数据又提供直流供电,极大地减少部署终端设备的电源和管理成本。结合IEEE802.3af/at标准内容,介绍了以太网供电系统的组成,分析了以太网供电的基本原理,展望了超越IEEE802.3at标准的应用。
The new Power over Ethernet （POE） technology allows Ethernet appliances to transmit data as well as provide DC power through the cat 5/5e and cat 6 unshielded twistedpair cable, greatly reduced the amount of power supply for terminals and the management cost. Combining with IEEE802.3 af/at standard, the paper introduced and the constitution of PoE, analyzed its basic principle and looks forward the application of standard beyond IEEE802.3at.
