RJ45 with the principle of POE function, do you understand?
Now let's introduce the working principle of POE.
The POE works through the (local area network) network cable to provide the original power required for ACCESS POINT (wireless access point) work. There is no need to separately connect the power supply cable to the new power supply mode. Many enterprises have begun to use POE to reduce the cost of building a wireless area network, because POE technology can save a lot of money and complicated lines for purchasing and installing a large number of power sockets and power lines. And ensure the reliability of the source of power. In addition, POE can also enable IP phone users to continue to use the phone when the power source is interrupted, and truly achieve the goal of blackout.
The working principle of POE is to let the DC power supply use the unused lines of the CAT5 cable to transmit power. It also has two functions: data transmission interface and power line. If the remote AP adopts POE, the system architecture will be simpler, the cable usage will be greatly reduced, the maintenance will be easier, the convenience will be more convenient, and the cost can be reduced. Moreover, the POE itself has both stability and security, and also has a remote monitoring function. It does not require an adapter, and the power supply of either 110V or 220V can be used universally.
Therefore, in the future, there will be more Ethernet products connected to the terminal products using POE technology. That's not to mention the network socket!
