Which technique is commonly used in wiring to reduce crosstalk?

Twisting wires is a widely recognized technique used to reduce crosstalk in wiring systems. This method involves pairing two insulated conductors and twisting them together along their length. The twisting helps to ensure that the electromagnetic interference (EMI) experienced by each wire is equal and, therefore, cancels out the interference due to their proximity to other conductors.

When wires are twisted, the loops created in the pair help to maintain a consistent impedance and minimize the potential for crossover signals from one wire to another. This is particularly important in communication cables, such as twisted pair cables used in Ethernet networks, where crosstalk can significantly degrade signal quality. The equal distribution of interference across the twisted pairs provides a more robust transmission capability and contributes to improved overall performance in data communication systems.

Other techniques, while they may provide some benefit, do not specifically target the mechanisms of crosstalk reduction as effectively as twisting does. Separating wires by distance, for instance, can help in certain scenarios, but it is often not practical in densely packed wiring systems. Shielding, on the other hand, protects against external interference rather than directly preventing crosstalk between individual wires. Using multiple channels might enhance data capacity but does not directly address the
