PARIS, Sept. 2 (Benin News / EP) –

The website USB Promoter Groupthe organization responsible for setting the standard for this connectivity, announced the version USB4 2.0, which will double to reach 80Gbps (gigabits per second) of data transfer with the same cable USB-C.

Today, the agency announced in a statement the first details of the USB 4 2.0 release, which is expected to double those transfer speeds to 80 Gbps.

These levels will be present in both existing 40Gbps USB-C passive cables and new 80Gbps USB Type-C active cables, which have yet to be released. The difference between these two types of devices is that passive devices do not have a built-in chip, while active devices do. to promote faster transfer.

Meanwhile, the USB Advocacy Group announced that specifications for USB-C and USB Power Delivery (PD), a charging protocol found in USB-C cables and connectors, had been modified, will be updated to allow these transfer levels and be compatible with USB4 2.0..

The group will also update protocols to enable better performance of USB 3.2, DisplayPort and PCI Express to “better use available bandwidth”. In the case of USB 3.2, its new architecture will allow it to exceed 20 Gbps of data tunneling speed.

The organization has also maintained backward compatibility of USB 4 2.0 with USB 4 1.0, USB 3.2, USB 2.0 and Thunderbolt 3 versions. USB Dev Daysan event with the developers which will take place next November.
