802.3bt PoE: Providing the Power of Possibility

July 30, 2015 at 10:00 AM

 

The realm of possibilities is expanding for Power over Ethernet (PoE) with the development of 802.3bt PoE.

 

The primary advantage of PoE is that it provides power to communication devices where no AC power source is available.  With no power lines to run, PoE saves on installation costs and makes configuration easier because the power source is within the data cables. More than one million devices are powered by PoE using the same cables that transmit Ethernet data.

 

However, the current version of PoE, 802.3at, peaks at 25.5 Watts, a modest power level that has limited use because many applications require more wattage.

 

The development of the 802.3bt standard will lift those power limitations with capabilities up to 49 Watts! 802.3bt PoE utilizes all four twisted pairs in Cat 5 and Cat 6 Ethernet cables providing more power. 802.3bt will be standardized with support for 10GBASE-T (10 Gbps Ethernet) and will be backward compatible with previous 802.3 versions.


PoE has evolved into a key technology for providing power and data simultaneously.  With 802.3bt PoE offering double, and possibly triple the power, new applications could extend to include 100 million devices worldwide and countless other possibilities.

 

As this new technology emerges, L-com will be developing innovative 802.3bt products and solutions to support your connectivity needs. In the meantime, we continue to support 802.3af and 802.3at applications with a wide range of products that help you save time and money with your wired and wireless networking installations.
