USB 3.2 Cable Lengths and Water Delivery
December 8, 2017
From USB 2.0 to USB 3.2, USB cables became shorter.
When USB replaced keyboards and mice, USB’s signaling rates of 1.5 Mbps and 12 Mbps. Transmitted more than enough data. If you know what a floppy disk is, those stored data in the Megabytes.
When USB 2.0 launched in 1999 it maintained the 5 meter cable length.
With USB 3.0 the cable length dropped to about 2-3 meters for 5 Gbps.
And with USB 3.1 it dropped to 1 meter for 10 Gbps.
USB 3.2 cables can be 1 meter because it uses 2 lanes of 10 Gbps.
The PHY / electrical signaling for USB 3.1/3.2 is exactly the same so cables can stay the same length.
