Power Over Ethernet Classes Explained

Power over ethernet delivers electrical power to poe enabled devices using your catx network cables.

Power over ethernet classes explained. Poe lets ethernet cables supply power to network devices over the existing data connection. Power over ethernet poe combines both data communication and power transmission for remote devices in the one cable therefore eliminating the need to run a separate ethernet cable to power a device. 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. Type 2 pse or pd an 802 3at poe compliant pse or pd.

The current is just enough to have each device start and do its operation. Power over ethernet poe is a networking feature defined by the ieee 802 3af and 802 3at standards. Our power without the struggle white paper makes the case for poe deployment in more detail and explains how poe can be used effectively. Powered device pd any device capable of receiving power over ethernet from a pse.

Poe capable devices can be power sourcing equipment pse powered devices pds or sometimes both. This way data and electricity is carried by one cable rather than having separate power cord. Because you don t need to run electrical wiring poe saves money in materials and installation time. 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.

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.

To find out about the myths and misconceptions about power over ethernet options for high power poe and a little more about how the technology works please continue to poe explained part 2. What is power over ethernet poe and what is it used for.

Power over ethernet poe explained part 2 demystifying poe myths and misconceptions poe is a recently developed technology and many people are put off adopting it by the raft of conflicting or out of date information that is available on the subject. Power over ethernet poe technology offers electrical current for wired ethernet lans local area networks through ethernet cables. It s also flexible especially for remote applications since it doesn t require a nearby electrical outlet. Increasingly used for voip phones wireless access points wap s and ip cameras poe eliminates the need for a nearby power outlet for these powered devices and allows a single cable to.
