For optimal performance, what is a recommended practice with installed Cat 5e cables?

Keeping Cat 5e cables away from power lines is a recommended practice for optimal performance due to the potential for electromagnetic interference (EMI). Power lines can generate electrical noise, which may disrupt the signals transmitted through the data cable. When data cables are installed in proximity to power lines, they can pick up this interference, leading to degradation in signal quality, increased error rates, and reduced network speeds. By ensuring adequate separation between data cables and power sources, the integrity of the data transmission can be maintained, ultimately enhancing the overall performance of the network.

This practice is an essential aspect of cable installation guidelines and helps ensure that the cabling system operates as intended, providing reliable connectivity over its expected range and minimizing issues related to crosstalk and external noise. In contrast, the other choices do not address the critical consideration of electromagnetic interference, making them less optimal for ensuring the performance of Cat 5e cables.
