USB 4 Cable was released in August 2019, making it the most recent iteration of the USB connection technology. It is an improvement over earlier technology because it allows for improved port utilization and quicker transfers. USB 4.0 also has a Type-C connection that can carry up to 40 Gbps of data and provide 100 watts.

Since PCs with USB 4.0 technology first hit the market in 2020, you may not have come across a USB 4 Cable. However, if you do purchase newer technology that includes USB 4, be assured that it is backward compatible with existing USB 2.0 and 3.0 devices. It can also connect to 4K and certain 5K displays.

A Result of USB 4.0 Tech – USB 4 Cable

Because it can dynamically monitor bandwidth requirements for connected displays and preserve the leftover bandwidth for data transport, the USB 4 Cable is more efficient than prior USB types at sharing between data and display protocols. Older USBs merely divided the bandwidth between display and data.

A USB 4 Cable can deliver up to 100W of power. An approved USB4 cable will include the USB logo as well as the number 20 or 40, depending on the speed (20Gbps or 40Gbps).

A single monitor can be connected to a USB4 port. The advantage of USB 4.0 is that it will allow manufacturers to develop more powerful hubs and docks at a lower cost. Because USB 4 devices do not need to be validated, we will soon witness a flood of USB 4 devices with varying degrees of quality, as we see with USB-C hubs today.

Of course, newer technologies are developed with the sole motive of driving development and elevation in the industry. As usual, USB 4.0 has also some great benefits.


  • Speed

The most evident is the data transmission rate. Large files or folders can be copied in a relatively short period with improved speed. In principle, USB 4.0 can achieve speeds of up to 40 Gbps. However, you should be aware that its speed is not constant and that not all USB 4 devices support the full speed.

USB 4.0 devices will be created for three signaling speeds based on market demand: 10 Gbps, 20 Gbps, and 40 Gbps. USB 4 Cable will also play a vital role here.


  • Compatibility

USB 4.0, like earlier USB versions, is backward compatible with prior USB versions. For example, it can be backward compatible with older USB specifications. It is also USB 2.0 and USB 3.0 compatible.

Furthermore, you should be aware that the USB C cables now will most likely be insufficient for USB 4.0. Fortunately, the earlier speeds are still supported. If you want to enhance your transfer rate, you must purchase additional cables and equipment.

The Bottom Line

Since the arrival of this technology, a certain rise in the tendency of using USB 4 Cables has also been noticed. Unfortunately, till now, there are only a few devices that support this technology. But rest assured that within a very short period, many compatible devices will be introduced.

You can consider SmartAVlink as we also offer USB 4 Cables to our customers. Our super speed 10Gbps USB 3.1 AOCs have multiple types, including AM-FM, AM-BM, AM-C, and C-C interface types.
