PoE(Power over Ethernet)即“以太网供电”,其在以太网电缆中加入直流电源,使得网络设备可以通过网线直接供电。 常用标准 PoE属于Ethernet 802.3标准的一部分: 802.3 af、802.3 at参考802.3第33章“Power over Ethernet over 2 Pairs”, 802.3 bt则参考802.3第145章“Power over Ethernet”。 版本差异 PoE各版本的差...
PoE（Power over Ethernet）技术，简单来说，就是通过网线来传输电力。它充分利用了现有的以太网基础设施，使得网线不仅能传输数据，还能为IP终端设备（如IP电话、无线接入点AP、IP摄像头等）提供电力支持。这种技术不仅简化了布线过程，还为IP设备的供电带来了极大的便利。PoE，也被称作基于局域网的供电系统（Power ov...

Commonly known as high-power PoE (Hi-PoE), Type 4 can supply a maximum power output of 90W to power devices like flat screens and LED lighting over Ethernet cables. IEEE 802.3bt Type 3 and Type 4 are backward compatible with the PoE and PoE+ standards. Detailed information about PoE vs...
PoE provides both power supply and data transmission over Ethernet cables to IP terminals, such as IP phones, APs, and IP cameras.
(PDs). In addition, the IEEE 802.3at (PoE+Power over Ethernet+. PoE+ is an IEEE 802.3at standard that provides 25.5W power on each port.) standard provides more power to PDs where up to 30.0 Watts of power on output is delivered on the standard copper cable. TheMobility Access Switch...
POE也被称为基于局域网的供电系统(POL, Power over LAN )或有源以太网( Active Ethernet),有时也被简称为以太网供电,这是利用现存标准以太网传输电缆的同时传送数据和电功率的最新标准规范,并保持了与现存以太网系统和用户的兼容性。 IEEE 802.3af标准是基于以太网供电系统POE的新标准,它在IEEE 802.3的基础上增加...
