Cable event! USB 3.2 standard announced compatible with old version 3.1, transfer rate doubled
The USB3.0 PromoterGroup alliance, which is composed of the giants such as Apple, HP, Intel, Microsoft, Texas Instruments, NEC, ST-NXP and other technology companies, announces the USB 3.2 standard will replace the current USB 3.1 standard today.
USB 3.2 supports multi-channel operation of host devices and peripherals. USB Type-C cables already support multi-channel operation. After upgrading to USB 3.2, host devices and peripherals can be used to create multi-channel solutions, allowing two channels of 5Gb / s or 10Gb / s. Due to the support of two channels of 10Gb / s transmission speed, compared with the current USB-C cable, the rate of USB 3.2 will be doubled.
The USB 3.0 Promoter Group stated that connecting to a USB 3.2 storage device, a USB 3.2 host can achieve a data transfer speed of 2 GB / sec. And the cable used is a USB-C cable, which has passed USB SuperSpeed 10 GB / s USB 3.1 certification. In addition, USB 3.2 is also compatible with older versions of devices.
In addition to dual-channel support, USB 3.2 continues to use SuperSpeed USB layer data rate and encoding technology, which will introduce updates to the hub specification to achieve seamless conversion between single-channel and dual-channel operations.
