Full-duplex operation means separate transmit and receive pairs, so the bus wiring needs four wires instead of two — a topology choice that matters for point-to-point or multi-drop links where simultaneous bidirectional communication is required. The 70 mV receiver hysteresis cleans up noise on long cable runs, reducing the chance of bit errors from ground shifts or reflections.
