Which aspect of a network cable plays a crucial role in determining its performance over distance?

The twist rate of a network cable is critical in determining its performance over distance. The twisting of the pairs of wires within the cable helps to reduce electromagnetic interference (EMI) and crosstalk between the wire pairs. This design feature enhances the cable's ability to maintain signal integrity over longer distances, as it allows the cable to effectively counteract external noise and signal degradation.

Each pair of wires is twisted together at a specific rate which defines the tightness and spacing of the twists. A higher twist rate typically allows for better performance, especially in environments with high levels of interference. Therefore, optimizing the twist rate helps ensure reliable data transmission at high speeds over extended distances.

While other factors such as cable length, the quality of connectors, and impulses can also influence network performance, the twist rate specifically addresses the fundamental design of the cable that directly affects how signals are transmitted and preserved in the presence of potential interference.
