Is Shielded Cabling the Right Choice for Your Cable Installation?
I just finished reading a very interesting article in the March/April edition of BICSInews Magazine (a great publication put out by Bicsi.org). 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?
