Power Over Ethernet Cable Requirements

Poe technology relies on the ieee 802 3af and 802 3at standards which are set by the institute of electrical and electronics engineers and.

Power over ethernet cable requirements.

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. What is power over ethernet poe and what is it used for. If you have such a device it will automatically detect when it is connected. This relatively high voltage allows efficient power transfer along the cable while still being low enough to be regarded as safe.

Powering over data comm cables. 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. Two primary elements are required in order to implement poe. Power over ethernet is injected onto the cable at a voltage between 44 and 57 volts dc and typically 48 volts is used.

Poe allows you to supply power to a networking device using the same cable that transmits the data. How power over ethernet poe works. 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 sourcing equipment pse the lan switch or source power delivered over ethernet.

Poe technology allows a single poe network cable to provide the required communication and electrical power to a variety of devices. The concept of supplying a direct current to a wire carrying a signal has been around since the 1900s. 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. Poe is designed to run over standard category twisted pair structured cabling.

Power over ethernet is produced by a device such as a network injector network switch or a router that has poe capability built in. The powered device pd the end device that accepts and uses power from. Power over ethernet poe stands for a proven method of delivering dc power over the same twisted pair cabling used for lan data transmission. 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 is the ability to deliver 48 vdc of power over the same copper cable as ethernet. 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.
