Power Over Ethernet Cable Vs Ethernet Cable

As an example a cctv camera would normally require both data cable and an external power supply from two separate cables.

Power over ethernet cable vs ethernet cable.

Power over ethernet often referred to as poe is a technology which provides electrical power over standard ethernet cables in most cases providing the power delivery simultaneously with the data signals sent from one device to another. Power over ethernet poe allows devices to be powered over 4 pair category 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. The ieee standard for poe requires category 5 cable or higher for high power levels but can operate with category 3 cable for low power levels.

Though it is extremely cost effective to utilize category cables for powering devices there are a number of factors that. Power over ethernet poe stands for a proven method of delivering dc power over the same twisted pair cabling used for lan data transmission. Poe technology allows a single poe network cable to provide the required communication and electrical power to a variety of devices. That means music photos video streaming and computer data may now be accessible in a previously difficult to cable space.

Power over ethernet or poe technology describes a system to pass electrical power safely along with data on 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. In actual application cables that installed in ethernet to connect with devices like switches routers and pcs and used as a common network medium for data transmission and power supply power over ethernet poe are called ethernet cables. This option unlike powerline adapters allows you to supply not only data signal but power as well to your pds powered devices.

Like power over ethernet poe technology that repurposes copper wiring powerline can send data over your homes existing wiring meaning cost to deployment remains low. 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.
