PoE(Power over Ethernet)是指通过网线传输电力的一种技术,借助现有以太网通过网线同时为IP终端设备(如:IP电话、AP、IP摄像头等)进行数据传输和供电。 PoE又被称为基于局域网的供电系统(Power over LAN,简称PoL)或有源以太网( Active Ethernet),有时也被简称为以太网供电。 为了规范和促进PoE供电技术的发展,解决...
Power over Ethernet 就是POE,是通过双绞线传输网络信号,同时给设备供电用的。至于用多少电,这个要看输入电压、电流:假设输入电压为220V,电流为0.1A,那么 P=UI=220*0.1=22W W=22*24=528W·h=0.528度 24小时开机的话大约耗电量是半度的样子,开一个月大概15度。

PoE,也被称作基于局域网的供电系统(Power over LAN,简称PoL)或有源以太网(Active Ethernet),有时甚至简化为以太网供电,是一种通过网线传输电力的技术。这种技术巧妙地利用了现有的以太网基础设施,使得网线在传输数据的同时,还能为IP终端设备(例如IP电话、无线接入点AP、IP摄像头等)提供电力。这不仅简化了...
Regardless of the size or configuration, all PoE switches are designed to provide power over the Ethernet cable to devices that support PoE. These devices, known as powered devices (PDs), include IP cameras, wireless access points, VoIP phones, and more. ...

这个就是以太网供电的意思:以太网供电是指在相同以太网铜缆上提供48V直流电源的能力。实施以太网供电需要两种主要设备--电源设备(PSE),即以太网上的LAN交换机或源电源供电,以及上电设备(PD),即从以太网电缆接收和使用电源以运行的终端设备。
Power over Ethernet (PoE) is technology that provides both power supply and data transmission over Ethernet cables to IP terminals, such as IP phones, APs, and IP cameras.It is also called Power over LAN (PoL) or active Ethernet.To standardize and promote the development of the PoE ...
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...
