Poe is simply a way of supplying power over that ethernet connection so using poe means a single ethernet cable can supply both electrical power and data.
Power over ethernet cable requirements.
Poe is designed to run over standard category twisted pair structured cabling.
How power over ethernet poe works.
Using data comm cables for providing power in addition to communicating signaling has been a hot topic in the data comm industry.
Power over ethernet poe stands for a proven method of delivering dc power over the same twisted pair cabling used for lan data transmission.
Power over ethernet is produced by a device such as a network injector network switch or a router that has poe capability built in.
Power over ethernet poe is great for supplying electricity to a variety of networking av and computing devices any device connected to the network without an outlet or adapter.
Power sourcing equipment pse the lan switch or source power delivered over ethernet.
Two primary elements are required in order to implement poe.
The 2017 nec was the first edition of the nec to address this issue which includes but is not limited to power over ethernet poe.
It also reduces the amount of building materials required to power and connect a device to the network by allowing a single cable to provide both services.
This relatively high voltage allows efficient power transfer along the cable while still being low enough to be regarded as safe.
This allows a single cable to provide both data connection and electric power to devices such as wireless access points waps internet protocol ip cameras and voice over internet protocol voip phones.
Power over ethernet poe technology sends 10 100 1000 mbps of data and 15w 30w 60w and up to 90w of power budget to devices over cat5e and cat6 ethernet cables for a maximum distance of 100m.
If you have such a device it will automatically detect when it is connected.
Powering over data comm cables.
The concept of supplying a direct current to a wire carrying a signal has been around since the 1900s.
Poe allows you to supply power to a networking device using the same cable that transmits the data.
Power over ethernet poe is the ability to deliver 48 vdc of power over the same copper cable as ethernet.
What is power over ethernet poe and what is it used for.
Poe technology allows a single poe network cable to provide the required communication and electrical power to a variety of devices.
Power over ethernet is injected onto the cable at a voltage between 44 and 57 volts dc and typically 48 volts is used.
Power over ethernet or poe describes any of several standards or ad hoc systems that pass electric power along with data on twisted pair ethernet cabling.
