USB Type-C has high-speed data transmission, fast charging, reverse plug, and others. It’s a standard that’s been widely adopted by various devices such as mobile phones, tablets, laptops, desktop computers, monitors, external hard drives, chargers, and many more. The transmission speeds of USB Type-C cables have also increased from 1020 Gbps to 40 Gbps, with 80 Gbps coming soon. This means that USB Type-C will become even more popular.

Due to its high-speed transmissions, fast charging, and reverse plug features, more and more monitor manufacturers are introducing USB Type-C to their products. However, when using Type-C cables for high-speed transmission, the high-frequency characteristics must be good quality, otherwise potential risks can easily occur.

How Serious are the Risks Caused by Crosstalk?

Crosstalk is the result caused by the coupling of two electrical wires which can interfere with the original signal and reduce its quality. When the crosstalk is larger, it can cause the bit error rate to increase. An increased bit error rate can cause monitor displays to start flickering or produce noise, resulting in a negative user experience. The crosstalk test is one of the most important quality indicators.

Crosstalk can be categorized into two types, namely Near End Crosstalk (NEXT) and Far End Crosstalk (FEXT). When both of these are serious, they can cause the potential risks mentioned above.

Allion has tested many USB Type-C cables throughout the years of experience. We’ve found that all bad-performing cables have issues with crosstalk. It can be said that the crosstalk test is crucial for high-frequency products.
