How can EMI problems be minimized in a wiring system?

Minimizing Electromagnetic Interference (EMI) problems in a wiring system can be effectively achieved by properly terminating unused conductors at both ends. When conductors are not terminated, they can act as antennas and pick up unwanted electromagnetic signals, which can result in interference with the data being transmitted through the other conductors. By terminating these unused conductors, you essentially remove the paths that allow interference to be induced in the cabling system. This practice not only enhances signal integrity but also promotes a more stable and reliable wiring environment.

In contrast, while using thicker cables and increasing insulation thickness can improve certain aspects of signal transmission and shielding from EMI, they do not specifically address the issue of unused conductors. Reducing cable length can also be beneficial, as shorter cables can reduce the potential for EMI. However, it is not a definitive measure against the effects caused by open or unterminated conductors. Terminating unused conductors directly mitigates the interference caused by these conductors, making it a key practice in minimizing EMI problems.
