TECHNICIANS NEED TO BE AWARE that the high performance network cables can provide is dependent on how they are pulled, handled and terminated.
Let’s look at a typical Cat5e/6 cable. There are the four twisted pairs, each twisted at a different rate to reduce crosstalk between the pairs. Care should be given during the cable pulling process not to exceed 25 pounds of pull strength. Violating the pull strength rating can cause the twists in the pairs to untwist or spread out, affecting the cable’s performance for the transmission of high-bandwidth data.
