Power Over Ethernet Cable Type

As well known not all cables are constructed to be able to safely support the.

Power over ethernet cable type.

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. Poe technology relies on the ieee 802 3af and 802 3at standards which are set by the institute of electrical and electronics engineers and. However if the camera is poe enabled only the network connection needs to be made as it will receive its electrical power from this cable as well. That s what power over ethernet poe can do.

This means that the requirement for cat 5 crossover cables is less than it might otherwise be. Ieee 802 3af 2003 type 1 poe. Cat 6 supports 10 gigabit ethernet only up to 164 feet of cable length. Power over ethernet allows devices to be powered over 4 pair category cables.

The first poe standard. 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. Serving two purposes with one cable. This technology allows network cables to not only carry data but also deliver electrical power to networked ip enabled devices before poe two connections an electrical connection and a network data connection would have been required in order to join devices like ip cameras to the network.

The ieee standards 802 3 af and ieee 802 3 at has ratified first two types of poe. What is power over ethernet poe and what is it used for. Many ethernet interfaces in use today are able to detect the type of cable whether it is a straight through or crossover cable and they are able to adapt to the required format. 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.

Specifying power over ethernet brings many advantages to an installation. 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. Power over ethernet standards and applications the ieee institute of electrical and electronics engineers standards for power over ethernet are 802 3af 802 3at and 802 3bt the detailed features are presented as follows. 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.

The category 6 augmented cable standard or cat 6a was created to further improve the performance of cat 6 ethernet cables using cat 6a enables 10 gigabit ethernet data rates over a single cable run up to 328 feet.
