How to Avoid Crosstalk

How to Avoid Crosstalk

You’ll come to find that the most common mistakes are usually the simplest to avoid. For instance, cross talk is very commonly created when connectors are not installed properly at both ends of the cable. Cross talk is the effect we get when electromagnetic energy from one cable leaves an imprint on adjacent cables. (You’ll often see this referred to as “noise.”)This usually isn’t a problem, however, since we twist wires inside Ethernet cable to cancel out this effect. So how, then, does cross talk become such a problem?

Cross Talk

You’ll notice that the Ethernet cable on the right has too much wire left over- we actually need to crimp the connector to the point where no internal wiring is visible. It’s important to note that while the wires do need to be separated to properly install a connector, they should only be separated as little as possible. Otherwise the lack of cancellation will create cross talk- and possibly cause hard-to-track failures in a network.
