新一代USB4 v2.0线缆，支持80 Gbps和240W PD。支持DP 2.1实现8K@60Hz或4K@240Hz。适用于尖端设备的最快USB线缆。
Built to the USB4 version 2.0 specification, this USB-C cable doubles the original USB4 ceiling to 80 Gbps while retaining 240-watt power delivery. It tunnels DisplayPort 2.1 for 8K at 60 Hz or 4K at 240 Hz output and stays backward compatible with earlier USB-C devices at their native speeds. An active design with embedded retimers sustains the data rate, which limits practical length to about 1 meter. The specification positions it as the fastest USB-family cable available, aimed at cutting-edge docks, external SSD arrays, and high-refresh displays. Where Thunderbolt 5 and USB4 v2.0 overlap on bandwidth, this is the USB-IF branded path. Prices range from $30 to $60.
