The main advantage of Powerover Ethernet (PoE)is delivery of data AND power over one Cat5e/Cat6Ethernet cable. PoE ends the need for AC/DC power supplies and outlets. A remote installation costs less thanfiberas no electrician is required. Ethernet cable costs lessand is often already installed buildings.

This article will explain the many advantages PoE has to offer. What began as an effort to squeeze more speed and power out of existing cabling has becomea force within the IT networking marketplace. Millions of dollars annually are being channeled into its development. The green movement is definitely saving technology some green.

Increased network efficiency allows organizations of any size to design the benefits ofPower over Ethernetinto their networks.

PoE allows you to add a device in awkward or remote locations. It is great for wireless access points, CCTV camera placements, and digital signage on the tops or sides of skyscrapers. It is suitable for IT network installations as well. Cables for IP devices and small, out-of-the-way networks can be boosted for distances beyond 100 meters/ 300 feet for a single device through the use ofPoE injectors.

PoE canbe used over existing copper telecom infrastructure.

When not to use PoE

PoE is not recommended for sending network data over long distances, or for extreme temperatures unless industrial designation is present.
