Power over Ethernet(PoE) Pinout Diagram
Power over Ethernet or PoE is a standard system that transmits or delivers electrical
power along with data through the same cable. We know that there are different types of
network cables are available such as cat6, cat7, cat5, etc, and different types of ports also
available such as RJ45. RJ45 has a total of eight pins and it connects with an ethernet cable
that consists of eight separate wires. All these eight wires are not used for the data
transmission, so some of them can be used for electrical power transmission. As per the
standard, the electrical current should interface with the data transmission and the cable
should be safe.
The Power over Ethernet system works under the standardization of the (Institute of
Electrical and Electronics Engineers)IEEE 802.3 committee. Generally, PoE delivers 47-57V
DC power. This PoE system is used for both data and power transmission purposes in
Internet Protocol(IP) cameras, Wireless Access points(WAPs), Voice over Internet
Protocol(VoIP), etc.
According to the IEEE standard cat5 or better cable is required for the transmission of
high power levels. But cat3 cable also can be used if less power transmission is required.
The PoE system was physically implemented under the specification of IEEE 802.3af-2003.
Also, we know that there are two categories for the RJ45 colour code - T568A and T568B.
