Cabling History: Way back when we started WKMN Training, Category 3 cabling was all the rage. Known as "telephone grade" wire, the big news was that you could run Ethernet (10BASE-T) over this inexpensive twisted pair cabling at distances up to 100 meters. The real benefit of being able to use this kind or cabling, however, is that it allowed you to create a more "structured cabling system" than the previous Ethernet LANs which relied on thin and thick coax. With thin and thick coax, troubleshooting network faults was a nightmare since there was no intelligence built into the system. With Category 3 cabling and intelligent hubs at the center of structured cabling systems, you suddenly had an intelligent device into which all stations were connected. This device could sense wiring problems like noise or Ethernet card problems like jabber. These intelligent hubs could automatically isolate bad wiring runs from the rest of the network and alert the network manager to the problem through a network management application. Amazing!

As network speeds increased, however, there was concern that Category 3 cabling would not support those higher speeds due to crosstalk and other potential problems. That's where Category 5 cabling came in. With more twists per inch, Category 5 cabling became the solution of choice for CDDI (FDDI over copper) and Fast Ethernet (100BASE-T). Category 5 cabling was much cheaper to pull than fiber.

Today, Category 6 cabling has emerged as the next evolution in copper, with hopes that it will support Gigabit Ethernet and even higher speeds. One interesting story recently emerged about Category 6 cabling, though. When initially pulled into a new building during early phases of construction, the cabling all tested well when tested for support for high-speed LAN use. Months later, when the building was completed, the same cabling was tested and failed. What happened? During construction, water found its way into the cabling and degraded it. Category 6 was found to be more easily damaged by water. Now, when buildings are being constructed, much more care must be taken to keep the cabling dry!

Of course if you want to guarantee the highest performance, longest life, and safest investment in cabling infrastructure, no one would argue that fiber is the way to go. Single-mode fiber and multi-mode fiber are the infrastructure of the 21st Century backbone network.

Our Network: Up until a few months ago, we had Category 3 cabling for our 10BASE-T stations and some legacy thin Ethernet for some of our older machines. We've replaced it all with Category 5 cabling and 10/100 switches.
