Cable length

Cable lengths are not explicitly specified in the USB Type-C specifications. However, the electrical requirements give practical limits

USB3.1 Type-C to Type-C cable effectively limits cable lengths to 1 meter.
USB3.0 Type-C to Type-C cable effectively limits cable lengths to 2 meters.
