Does the 40Gbit really go through (or at least 20Gbit)? Unfortunately, there are tons of USB cables that claim to be USB IF certified, but this is not really the case if you read the chip with an appropriate device.

Question

Answer

To ensure that the USB 4.0 cable from PowerGuard achieves the specified data transfer rates, beberapa points should be observed:

## Certification
The cable must be USB-IF certified, which provides a certain guarantee of compliance with USB 4.0 standards.

## Cable specifications
USB 4.0 cables that reach the full performance of 40 Gbit/s require special cables that support this speed. For 40 Gbit/s, the cable length must not exceed 0.8 metres.

## Compatibility and material
The cable should be made of high-quality materials such as copper and equipped with nickel-plated, gold-plated contact surfaces to ensure the required data transfer rate.

## Practical check
To ensure that the cable actually achieves the specified rates, it should be tested with an appropriate device that supports USB 4.0. This can help determine whether the cable actually delivers the specified 20 Gbps or 40 Gbps.

If the cable fulfils all these criteria and is certified, it should be able to achieve the data transfer rates of 20 Gbps or 40 Gbps.
