Power Over Ethernet Cable Length

What is power over ethernet poe and what is it used for.

Power over ethernet cable length. Poe technology relies on the ieee 802 3af and 802 3at standards which are set by the institute of electrical and electronics engineers and. Yes power over ethernet poe will will only power the unit so long as there is enough voltage to power the unit at the end of the cable run. When you invest in cat 6a cable you re making a decision to support your organization and its technology infrastructure for the long term. The first poe standard.

Extend ethernet and poe ethernet and poe both restrict cable distances to 100 metres 328 feet between network ports. It provides up to 15 4w power at voltage range from 44 0 57 0v. 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. The maximum distance you can power a device will vary depending on the access point and the voltage it requires as well as the voltage provided by the power supply and the quality of the cable.

However poe powered devices such as ip cameras and wireless access points frequently must be located at far greater distances from the nearest network switch or power outlet. 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 poe calculator by poe world will calculate the total power required for any device including cable loss by any type or length of cable over ethernet or not it calculates the voltage drop and power required by both the device and the loss in the cable. However the poe has limited of 100 meters which has relative to both network communicating and voltage drop of the power.

It should be noted that cat7 cable has harsher distance limits than cat5e cat6 and cat6a. Ethernet 100 meters 328 feet there are a few different versions of ethernet cable but they all have a maximum distance of 100 meters 328 feet. 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. Ieee 802 3af 2003 type 1 poe.

With this type of cabling system in place you ll be ready to support next generation wireless 4 pair power over ethernet poe hdbaset and digital buildings and other technologies just entering the picture. The poe provides the solution to transmit the power and network communicating over single ethernet cable. It saves the installation cost.
