PoE is the abbreviation of Power over Ethernet. It's
a standard that allows Ethernet connections to simultaneously transfer data and
power over a single network wire. Electrical current, as well as the data
ordinarily carried by an Ethernet cable, goes via the Ethernet cable with PoE
enabled devices. Throughout the rest of this article, we’ll talk about how PoE
works, what is it used for and what are the advantages of PoE.
How does PoE work?
Ethernet cables are typically built with extra
data carrying capacity in mind. Most cables have four pairs of wires, but only
use two of them - the exception being Gigabit cable, which uses all four pairs
to give larger, quicker data carrying capability.
Most Ethernet cables include spare wiring
capacity, which PoE takes advantage of. To make a power circuit, the two pairs
of wires that aren't used for data are employed as conductors. Any Ethernet
cable with a Category 5 or higher rating is safe to carry current, and because
the data and power are carried on distinct bundles of wire, there is no chance
of interference.
PoE requires a device that can be powered by
PoE, as well as a specialized PoE router or an ordinary router with an
intermediary power switch, in addition to an appropriate Ethernet cable.

What is it used for?
The most common PoE applications:
Advantages of PoE
Cost Saving: By lowering the time and cost of
installing electrical power cabling, Network cables do not require the
installation of a certified electrician and can be placed almost anyplace.
Flexibility: Devices like IP cameras and
wireless access points can be placed wherever they are needed most, and
repositioned easily if necessary, because they are not linked to an electrical
outlet.
Safety: The intelligent PoE delivery system is
designed to safeguard network equipment from overload, under powering, and
wrong installation.
Scalability: PoE makes it simple to add new
equipment to a network.
