What is the main benefit of using balanced signaling in serial cables?

The main benefit of using balanced signaling in serial cables lies in its ability to minimize interference, which allows for longer cable runs without degradation of the signal quality. Balanced signaling works by utilizing two complementary signals sent over a twisted pair of wires. This configuration cancels out any electromagnetic interference that might affect the signals, making it less susceptible to crosstalk and noise from other sources.

As a result, balanced signaling can maintain reliable data transmission over greater distances compared to unbalanced signaling methods, which may suffer from signal loss and distortion due to interference. This feature is particularly advantageous in environments with a lot of electrical noise, ensuring that the integrity of the communication remains intact over longer distances.

While aspects like faster transmission speeds, cost reduction of materials, or simplified wiring processes may hold merit in other contexts, they are not the primary benefits associated with balanced signaling in the context of serial communications.
