We've seen network speeds increase from 10 million bits of information per second, over Category 3 wire, back in 1991 to 1 billion bits (called Gigabit Ethernet) today. With bandwidth increasing and reliance on the network at an all time high, getting information to where it needs to be is becoming more challenging than ever. Ask any IT Manager what their most common network problem is and you will most likely hear them rant about cabling issues. In fact, cabling problems, which account for over 50% of network problems, cost companies millions annually. The most common problems are:

• Low attenuation

• Poor NEXT (near-end crosstalk)

• Poor ACR (attenuation-to-crosstalk ratio)

• Poor delay skew (data arrives at different times)

• Poor return loss (also known as "echo")

• Splices in cable

• Mis-labeled cables

All of these problems can be avoided if the cabling is installed and tested properly. The cable must be installed following strict and specific guidelines and the testing must be done using the right equipment calibrated for the latest standards (called certification).
