Next Generation PoE: A Hot Topic (or is it?)

By: Susan Larson, Marketing Communications Manager

Power over Ethernet is not a new technology. In the late 1990’s, while I and my fellow Gen X-ers were busy buying grunge-flannel shirts and mourning the end of the Seinfeld series, some much more productive folks were developing a way to transmit simultaneous voice and data traffic over the same IP network. Eliminating the need for a separate phone system certainly had financial benefits, but getting rid of the traditional phone jack meant phones would be left without a power source. So, those same productive folks went back to the lab and figured out a way to transmit power along with voice and data traffic. Hence, Power over Ethernet (PoE) was born.

Fast forward 15 years. We are powering more devices than ever before via PoE technology. What started out on phones has already expanded to powering other devices like security cameras and wireless access points. The more systems and devices an organization can power through its IP network, the more money it will save on installing, maintaining and upgrading disparate systems, such as HVAC, building automation, and access control. Sounds like a financial win for any organization, right?

Despite the financial benefit, High Power PoE presents a challenge: HEAT. Heat is no friend to IP traffic on copper cabling. It weakens signal strength (attenuation) and makes IP traffic more prone to errors.  More errors can cause your network to slow to a crawl and/or possibly lead to rebooting.

Accepting the challenge

Never ones to shy away from a challenge, the engineers at Berk-Tek have come up with several solutions for High Power PoE that will minimize heat rise and ensure your network performs at peak levels. Most recently, they’ve been busy testing heat rise when power is applied to various types of cabling in different installation scenarios. View their latest Test Report here.

Beat the heat

Here are a few other ways that Berk-Tek is working to help you beat the heat with High Power PoE:

  1. Berk-Tek’s LANmark-1000 (Cat 6), LANmark-2000 (Cat 6), and LANmark-XTP (Cat 6A) products have all been listed to 75˚C (above and beyond the 60˚C listing required by the standards). These products provide you with an extra temperature budget, which can be spent in operating environments where temperatures can climb above 45˚C and/or allow more heat generation through PoE.
  2. LANmark-XTP (Cat 6A) is the absolute best performing solution for High Power PoE. Its discontinuous shield is specially designed to not only provide outstanding electrical performance without grounding, but also to provide outstanding PoE performance by significantly limiting heat rise.
  3. To control noise, Berk-Tek has developed a proprietary algorithm called TEK-Twist Technology that essentially optimizes the cable twist for simultaneous transmission of voice, data, power, and video.

The bottom line

When evaluating your network infrastructure requirements, don’t just look at what your needs are today. Think ahead three to five years. Chances are you’ll be powering many more devices than you are now, and you’ll require significantly more power to flow through your network. Be sure to install something that can handle the demands of tomorrow.
