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...
一些厂商开发了自己的标准扩展,以提供更高的功率: Cisco的“通用以太网供电”(Universal Power over Ethernet),提供高达60瓦。 HDBaseT规范,由消费电子厂商联盟开发,支持通过四对类别5e或6电缆提供高达100瓦的电力。 Goals of the PoE Standard IEEEPoE标准列出的目标包括: Power: 通过双绞线电缆提供电力和数据。 Saf...
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 ...
以太网(Ethernet Network),不同于同步光纤网(SONET: Synchronous Optical Network)和无线局域网(WLAN: Wireless Local Area Network),在通信的两端之间存在能够导电的物理介质,俗称网线,因此在传输网络信号的同时能够轻松的提供电力传输。 现在的PoE标准已经不是简单的将8根网线中没有用到的4根用来做供电线了。首先,...

Power Sourcing Equipment (PSE) is any equipment that is able to provide and source power on the twisted pair Ethernet cable, such as PoE switches, extenders, and injectors. PSE needs to be highly reliable to prevent device failure and ensure uninterruptible operations of connected PD. With...
Power over Ethernet is a process where devices known as power sourcing equipment (PSE) provide a direct current (DC) voltage over a standard Ethernet cable to another connected device known as a powered device (PD). This allows for the powering of devices without the need for a local power...
