OverView:
POE (Power Over Ethernet) is a technology solution that, under the case of no any change for current Ethernet Cat5 wiring/cabling infrastructure, not only transfer data signal but also provide direct current power for some IP based terminal device (like IP telephony, Wireless LAN access point, Network camera, etc.).
POE technology can minimize the cost while ensuring the normal operation of the existing network and the safety of the existing structured cabling.
POE(Power over Ethernet) adapter provide a power solution for the related device, it can supply power and simultaneously be a media for data transfer in anywhere there is a cat5 cable.
POE also known as power system based on local area network (POL, Power over LAN) or Active Ethernet, sometimes it is briefly called Power Over Ethernet, this is the latest standard specification of transferring data and delivering power while taking advantage of existing standard Ethernet transmission cable, and preserve the compatibility between user and the existing Ethernet system.
IEEE 802.3 is new standard of POE in the base of Ethernet power system, which add related standard in power over network cable directly through IEEE 802.3, it’s an extension of existing Ethernet standard, and it is also the first international standard in power distribution.
POE principle
There are 4 pairs of twisted pair for the standard CAT5 network cable, but there are only 2 pairs ones are adapted/applied in 10M BASE-T and 100M BASE-T. IEEE802.3 allows two solutions, when power delivered through free pin, PIN 4&5 connect positive”+”, PIN 7&8 connect negative”-”, while power delivered through data pin, add DC power on the central point of the transmission transformer, without affecting the data transfer. In this case, pin 1&2 and pin 3&6 are at any polarity. IEEE802.3 standard will not allow above two applications happen at the same time. The PSE(Power Source Equipment) provide only one power solution, but the PD(Powered Device) must be adapted to above two application solutions at the same time.
Advantage of POE
1. Cost saving. As it’s just one instead of two pieces of net cable for the installation. PD, in most cases, are installed at where is hard to access AC power. Along with increasing device connected to Ethernet, if there is no need to provide local power for device, it will greatly reduce the cost of installation and simplify the management.
2. It’s easy to install and manage. It allows users to use original device and POE device together on internet automatically and safely, which make rooms for original device coexist with Ethernet cable.
3. It’s safety. As POE supply terminal device just provide power for those device that need power. The Ethernet cable will generate voltage only when it’s connected between POE and Powered Device, so it have eliminated the dangerous of power leakage on cable line.
4. It’s easy to manage network equipment.
