Buses typically use differential cables because they offer several benefits. One significant benefit is that differential cables effectively eliminate common-mode noise. This is important because when multiple devices are connected in a network, common-mode noise can cause communication errors and degrade the overall performance of the network.
Differential cables also offer better noise immunity compared to standard cables. This is due to the fact that differential signals are transmitted over two wires with opposite polarities, which results in noise being canceled out. In other words, any noise picked up by one wire is effectively canceled out by the opposite polarity on the other wire.
Another advantage of using differential cables is that they allow for longer cable runs without the risk of signal degradation. Differential signals are more resistant to attenuation, which means they can travel further without a loss of signal strength.
Overall, the use of differential cables in buses is a positive thing as it helps to ensure reliable and stable communication between devices on the network.
