Which factor does NOT improve cabling performance?

The factor that does not improve cabling performance is ignoring testing requirements. In a structured cabling system, proper performance is critical for ensuring data integrity, reliability, and overall network efficiency. Testing requirements are established to identify potential issues such as signal loss, interference, or noncompliance with industry standards.

When these testing requirements are ignored, underlying problems can go unaddressed, leading to degraded performance and potential failures in the network. For example, without proper testing, a cable fault may remain undetected, resulting in poor connectivity or slower data transmission rates. Thus, adhering to testing requirements is essential for achieving optimal cabling performance, making ignoring them detrimental instead of beneficial.

In contrast, proper installation techniques, regular maintenance checks, and using shorter cable lengths are all practices that positively influence cabling performance. Proper installation ensures that cables are installed according to standards to minimize signal loss and potential damage. Regular maintenance helps identify and address issues proactively before they impact performance. Using shorter cable lengths is often favorable as longer cabling can lead to increased signal attenuation and possible interference.
