Which of the following is NOT a good practice in cable handling to avoid interference?

1. Not using staples

2. Avoiding sharp bends

3. Pulling and stretching cables

4. Using appropriate cable ties

The correct answer is: Pulling and stretching cables

Pulling and stretching cables is not a good practice in cable handling because it can lead to physical damage to the cable itself, such as internal wire breakage or degradation of the insulation. This damage can result in reduced performance or increased interference due to the compromised structure of the cable. Proper handling techniques should prevent stress on the cable, ensuring it maintains its integrity and the quality of the signals it carries. Conversely, not using staples, avoiding sharp bends, and using appropriate cable ties are all critical practices for preventing interference. Staples can create sharp points that might damage cables, while sharp bends can introduce stress and cause signal loss. Using appropriate cable ties helps to neatly organize cables without putting undue strain on them, thus preserving their performance.
