Why do the four pairs of network cables have different winding densities?

The reason why the four pairs of network cables have inconsistent winding densities is to reduce the impact of interference and cross-interference and provide better signal transmission quality and reliability. Detailed introduction: 1. By winding the wires together and using different winding densities, the spread of interference can be reduced; 2. By using different winding densities, the mutual interference of signals during transmission can be minimized; 3. Using different winding densities in the design of network cables can make the cables easier to bend and install, and can provide better tensile strength and durability.

The four pairs of wires in the network cable (also known as Ethernet cable) have inconsistent winding densities in order to reduce the impact of interference and cross-interference. Two conductors (usually copper wires) in each pair are used to transmit data signals, while four pairs of wires carry multiple signals simultaneously, including data signals and power signals.

The inconsistency in winding density can reduce interference between signals. When data signals pass through a pair of wires, electromagnetic interference may occur from power signals and data signals in other wires. By winding the wires together and using different winding densities, the propagation of interference can be reduced.

In addition, the inconsistent winding density also helps reduce cross-interference. Cross interference refers to the phenomenon that signals transmitted between different lines interfere with each other. By using different winding densities, mutual interference of signals during transmission can be minimized.

In addition, different winding densities can also provide better flexibility and reliability. By using different winding densities in the design of network cables, the cables can be made easier to bend and install, and can provide better tensile strength and durability.

In summary, the inconsistent winding density of the four pairs of wires in the network cable is to reduce the impact of interference and cross-interference and provide better signal transmission quality and reliability. This design reduces electromagnetic interference and cross-interference while providing better flexibility and durability.
