What kind of network cable should the PoE device use?

Power over Ethernet (PoE) is a technology which use network to provide equipment with direct current. Since the nineties of the 20th century, PoE technology with reliable and cost-effective features have been widely respected, PoE equipment is also very common in our daily life, then, what kind of cable we should use to PoE equipment power supply? This tutorial will give you an answer.PoE standardIEEE802.3.af and IEEE 802.3.at are the first standards for PoE, and these two standards of power supply can provide 15W and 30W of direct current to the PoE equipment via cable, respectively. These two standards are generally suitable for low power PoE devices such as IP phones, wireless APs and some cameras. In order to meet the needs of high-power PoE equipment, people later developed the IEEE 802.3.bt standard, in line with this standard power supply equipment can provide high-power PoE equipment with 60 watts or even 100 watts of direct current. However, when supplying power to high-power ..

What 802.3 Standard Originally Defined Poe Functionality?

Definition:IEEE 802.3 is a working group and a collection of IEEE standards produced by the working group defining the physical layer and data link layer's media access control (MAC) of wired Ethernet. This is generally a local area network technology with some wide area network applications. Physical connections are made between nodes and/or infrastructure devices (hubs, switches, routers) by various types of copper or fiber cable. 802.3 is a technology that supports the IEEE 802.1 network architecture. What 802.3 Standard Originally Defined Poe Functionality When Was the Standard Enhanced Powering network devices can sometime present problems, especially if they are located remotely. One convenient solution is to supply the power over an Ethernet LAN cable. Power over Ethernet, is defined under two IEE standards, namely IEEE 802.3af and later IEE 802.3at which defined a number of enhancements.This Power over Ethernet, PoE is now being used for a wide variety of ap..

How to Use PoE Technology to Build Enterprise Wireless Network?

With the popularity of smart phones, laptops and other mobile devices, WiFi has become an indispensable part of the home and enterprise networks, and there are many ways to deploy WiFi networks. Among them, through the PoE technology is considered as the most commonly used ways to build enterprise wireless network, this tutorial will be described in detail. Using PoE technology to power for wireless APThe easiest way to provide WiFi to mobile devices is to set up a wireless AP on the wall or ceiling (see below), and in addition to access network, wireless AP also need to be powered by power cable to ensure work properly. Now, there are two main ways to power for wireless AP: powered by direct current or remote powered by PoE technology. However, due to the deploy location of wireless AP is very special, powered by a DC power supply does not always work, while PoE technology can use the existing Cat5 or Cat6 of network cable to transmit data signal, and also can send the current to..

4 Connection Methods for PoE Switches

1. Switch and terminal's support for PoEIn this method, PoE switches connect wireless AP and network cameras which support PoE power directly through the network cable. This method is the simplest, but is needed to pay attention to the following two points:1). Determine whether the PoE switch and the wireless AP or network camera are standard PoE devices.2). Carefully confirm the purchased network cable specifications. The quality of the cable is critical. The cable of poor quality will cause that AP or IPC cannot receive power or continue to restart.2. PoE supported by switch but not by terminalIn this method, PoE switch is connected to PoE splitter which separates the power supply into data signals and power. It has two output lines, one is the power output line and the other is network data signal output line, that is, the ordinary network line.  Power output 5V / 9 / 12V, etc. can match a variety of DC input non-PoE power receiving terminal and support IEEE 802.3af / 802.3at s..
