10Gbps USB3.1 demonstrated at CES 2014



10Gbps USB3.1
The current USB 3.1 interface allows you to charge devices as well as a faster data transfer, or the both. At the consumer electronics trade show CES 2014 they have demonstrated the capabilities of the USB 3.1 adopted the USB 3.1 standards by Rave Jeff Craft, president of the USB Implementers Forum.

This provides 10 Gb / s double the USB 3.0 speed and enables the Power Delivery to charge devices with up to 100 watts - under certain conditions. The first demonstration shows a fitted with two SSDs PC (one per PCIe and one USB 3.1), which achieved a reading rate of around 1,000 MB per second, according to the ATTO Disk Benchmark, thanks to the gross data rate of 10 instead of 5 Gigabit per second, and only 3 percent protocol overhead instead of the previous 20 The latter is made possible by the 128b-/132b- instead of the previous 8b/10b encoding, thus a loss of 4 bit per 132 bits.

A special FPGA chip in the hub allows power delivery and also to connect a monitor at the same time. Another function that supported by USB 3.1 is the Power Delivery in the form of six profiles ( 0-5), who can afford each 10, 18, 36, 60 and 100 watts.

Beyond 36 Watt Micro- USB connectors are not provided, only the large connector of type A and B should engage. The devices can negotiate their skills before. This corresponds to what the proprietary devices support already, but just in a standardized form. Jeff Rave Crafts presentation included a printer connected to a hub monitor and a notebook from which a trailer was transferred to the display. USB 3.1 is not fluent in HDCP, which are protected under other Blu-rays. Since the standard has already been adopted, Rave Craft expects the first products at the end of 2014 to be available in the market.
