New specification of USB "USB 3.2" is multi-lane operation if supported terminal, maximum speed is doubled USB 3.1


The USB 3.0 promoter group announced the specification of "USB 3.2". It is said that the transfer speed becomes faster than usual USB 3.0, and if it is maximum, transfer of 10 Gbps × 2 becomes possible. Because USB 3.1 is 10 Gbps, it can be said that the speed is twice as fast as simple numbers.

As a new standard of USB, there is "USB Type-C" which can be inserted without front and back cables adopted in smart phones and Wi-Fi routers, but "USB 3.2" is another standard different from this. It supports "multi-lane operation" that allows data to be transferred simultaneously in multiple lanes, and can transfer 5 Gbps × 2 lanes or 10 Gbps × 2 lanes.

It is necessary for the device side to support multi-lane operation, but the cable can output speed of 2 GB (16 Gbps) or more per second even with the conventional USB 3.0 cable.

The final specification has not been established yet at USB 3.2, and the official release of the specification will be after the event of "USB Developer Days North America" ​​held in September 2017.
