The Need for (More) Speed: USB 3.2 is Coming

The USB Promoter Group recently announced the pending release of the USB 3.2 specification. While this is an incremental update, it turns out it is a very important one as it opens the door for multi-lane operation between USB 3.2 devices. What does this mean to you? Speeds of up to 20Gbps per second or the doubling of data capacity and speed of current USB Type-C™ cables.

The big question when these updates are rolled out is, “Will the current cables work or do I need to buy new cables?” I am happy to report multi-lane capability was planned for in advance, so any existing USB Type-C™ cable that is certified for SuperSpeed USB 10Gbps will support the new 3.2 specification.  It is also backward compatible with USB 3.0 and earlier devices.

Keep in mind though, to obtain the full benefit of this increase in performance, a new USB 3.2 host must be used with a new USB 3.2 device and an appropriate certified USB Type-C™ cable. As of this writing, there are no known USB 3.2 capable device hosts or devices, and the final draft of the specification will not be ready until September 2017.

As always, Comprehensive will continue to keep you informed and will always have the next generation of connectivity available to you when you need it, so visit our website and blog again soon. (To read the entire press release from the USB Promoter Group, click here.)
