USB Cable

USB4 enables multiple devices to dynamically share a single high-speed data link. USB4 devices must support a data communication bit rate of at least 20 gigabits (Gbit/s). The current version allows bit rates of 40 Gbit/s (since USB4 version 1.0) and 80 Gbit/s (since USB4 version 2.0).USB4 is only defined for the USB-C connector and its Type-C specification regulates the connector, cables and also power delivery features across all uses of USB-C cables, in part[4] with the USB Power Delivery specification.

The USB4 standard mandates backwards compatibility to USB 2.0, USB 3.x and DisplayPort connections.The dynamic sharing of bandwidth of a USB4 connection is achieved by carrying virtualized "tunnels" of other connections. This includes tunneling of USB3 and DP connections. Other protocols, such as PCI Express and Ethernet can also be tunneled, even without a way to access these directly directly from USB4 ports.
