What factor can negatively impact the performance of installed cables over time?

The factor that can negatively impact the performance of installed cables over time is environmental factors such as temperature variations. Cables are susceptible to changes in their surrounding environment, and extreme temperatures can cause physical changes in the materials used in cable construction. For instance, high temperatures can lead to increased resistance, while very low temperatures may cause materials to become brittle. These changes can ultimately degrade the performance of the cable, reducing its efficiency and lifespan.

While regular maintenance and proper cable management are practices that enhance cable longevity and performance, environmental factors can create conditions that deteriorate the cable irrespective of maintenance efforts. Similarly, updated industry standards are aimed at improving the installation and performance of cabling systems rather than negatively impacting them. Thus, understanding the effects of environmental factors is crucial for ensuring optimal cable performance over time.
