Is Shielded Cabling the Right Choice for Your Cable Installation?

Shielded Cabling Solutions

I just finished reading a very interesting article in the March/April edition of BICSInews Magazine (a great publication put out by  Written by Robert Carslon, V.P. for Siemon (and, on a personal note, Bob is an awesome singer – if I do say so myself!), the article discusses the need to begin cabling for 10 Gigabit Ethernet (GbE) today to handle the vast amounts of data and complex images flying through our LAN systems.  Bob gives a great example of our “need for speed” as he states “Assuming best case data throughput, a raw image sized at 30 Gb takes just 24 seconds to transmit over a 10 GbE network but can take as long as 40 minutes to transmit over a 100 megabit (Mb) Ethernet network.”

The article continues with discussion of issues involved with IP convergence, PoE and concerns with interference from EMI and RFI. The answer, Bob concludes, is shielded cabling. He backs up his statements with four major rationals for utilizing this technology:

  • Provides superior network performance – the shield practically eliminates alien crosstalk (AXT) and eliminates the need for time-consuming AXT field testing
  • Facilitates work area density – utilizing shielded cables allows for “cable sharing” (use of a single cable for multiple applications!)
  • Better dissipates heat for PoE – a more stable transmission at elevated transmissions reduces the need for shorter channels and better supports facilities deploying IP convergence
  • Provides EMI/RFI immunity – while remaining a cost-effective copper solution, as compared to fiber optic cable with higher equipment costs


This is a brief overview to an article you really need to read for yourself. When you finish – let us know if you agree – Is shielded cabling the right choice for your next cable installation?

    I also read the article and found it quite informative. Any chance the U.S. will head in that direction?

      The US is already headed in that direction, the biggest growth of shielded systems is in Data Centers where category 6A cabling and higher is recommended to support higher speed applications including 10GBASE-T. Simply put, the higher the frequency, the more suceptible the cabling is to noise. As networking applications continue to evolve, a shielded or fiber system will be required. Siemon is installing more shielded than UTP 6A and higher systems in the US and globally. After customers are educated about the benefits of shielded cabling they often decide for themselves that shielded cabling is the right choice for their installation. My prediction is that you will see more cabling manufacturers in the US offering and leading with shielded solutions in the future.
