Ucoax provides USB-IF Certified 40Gbps USB4 Cable

USB4 is, like USB 2.0, USB 3.0, and all the subsequent iterations, a USB specification developed and released by the USB Implementers Forum. It builds on the strengths of USB 3.2 2x2 by maintaining the USB-C connection, but mandates a minimum throughput of 20 Gbps, and opens up the potential for double that. It also improves compatibility with Thunderbolt standards, allows tunnelling of DisplayPort and PCIExpress to better support higher resolution monitors over USB, and mandates USB Power Delivery.

It`s an altogether modern connector that will be more widely available than the competition, offer comparable features, and deliver exciting performance enhancements to anyone used to the older USB standards.

It also brings the big quality of life improvement of starting from scratch with a single naming convention. USB4 cables and devices have their specifications and that`s how they`ll remain, with no intention from the USB-IF of re-framing as it did with USB 3.0 as it morphed into 3.1, then 3.2 and its various generation designations.

The Benefits of USB4

USB4 has all the benefits of previous generations of USB ports, with a number of exciting additions that make it a great alternative to the likes of Thunderbolt 3 and Thunderbolt 4.

For raw bandwidth, USB4 mandates a minimum speed of 20 Gbps throughput. That`s technically only as fast as the best USB 3.2 Gen 2x2 ports, but that`s the floor with USB4, not the ceiling. It`s possible for devices built with USB4 to support up to 40 Gbps instead, with devices given specific logos on their packaging and ports, to show the maximum bandwidth available.

That 40 Gbps may not be guaranteed, but in devices that support it, it makes USB4 just as fast as Thunderbolt 3 and Thunderbolt 4, and one of the highest bandwidth solutions for transferring data.

That huge bandwidth also opens up support for higher resolutions using the DisplayPort Alt Mode 2.0 protocol. That gives it the ability to output to and display up to 8K resolution at up to 60Hz with HDR10 color.

USB4 also supports DisplayPort 1.4 and PCI-Express tunneling, which lets it use smart bandwidth management to make the most of multi-use connections. For example, if you were using a USB4 connection to output to a 4K display, but also wanted to use that same connection for data transfer at the same time, the host system can allocate the maximum available bandwidth to the data transfer, without impeding the stream of 4K video. That`s more nuanced than the 50/50 split that more traditional DisplayPort Alt Mode allows, and should make for a more efficient and versatile connection than previous generations of USB.

All USB4 hosts and devices will have to support USB Power Delivery, too, making it possible to charge more capable devices like laptops and tablets over a USB4 connection. There`s no guarantee on the amount of power that will be provided by the device or host, but technically USB4 Power Delivery can be anything up to 100W, so some devices will be able to charge extremely quickly.

USB4 was also designed from the ground up to be backward compatible with previous USB generations. That means it works with legacy USB 1 and USB 2 generation devices, leveraging dedicated wires within the USB-C connector to do so. However, as the USB-C connector was only implemented with later USB 3.1 devices, a USB-A to USB-C converter will need to be used for connecting older USB 1 and USB 2 devices over USB4. The same goes for any USB-A 3.0 or 3.1 devices, with USB-C 3.1 and 3.2 devices directly compatible with USB4 in all cases.

Thunderbolt 3 compatibility is also mandated for all USB4 hubs, although not all USB4 devices will support it. Conversely, Thunderbolt 4 devices must support USB4.

Of course, to take advantage of USB4 ports you`ll need USB4 cables that are up to the challenge. Cable Matters offers a wide range of USB4 cables and Thunderbolt 4 cables that also offer full compatibility with USB4.
