Electronic equipment connects with two main types of wiring: signal or communication cables and power cables. Communication cables carry voice, video or data signals, and power cables carry either alternating current (AC) or direct current (DC) electricity.

Cables as Transmitters
As electrical current or electronic signals travel along a wire, they create unwanted electromagnetic waveforms that emit in parallel to the cable. These signals decrease in strength with distance.
Cables as Receivers
These same cables also act like receiving antennas. Any signal that crosses them can be induced into the conductors.
Separating Communication and Power Cables
Since the power of unwanted transmitted signals from a cable decrease with distance, the farther away another cable is, the less power will be induced. Always separate communication and power cables as far as possible, in parallel runs, to prevent unwanted signals from entering.
Installing cables in a grounded metal conduit reduces the amount of unwanted signals they can either transmit or receive. When you can't separate cables far enough, try installing them in a conduit.
