The 6.6ft (2m) Active Thunderbolt 4 cable enables full Thunderbolt 4 capabilities and outperforms passive cables beyond 3.3ft (1m) length. An active integrated chipset minimizes signal degradation for consistent 40Gbps output at distances of up to 6.6ft (2m), while passive cables deliver limited performance beyond 3.3ft (1m) due to signal loss.
