30 cm USB4 Extension Cable

This 30 cm USB4 extension cable connects USB4 hosts to USB-C monitors, drives or docks. It supports up to 40 Gbps data transfer and delivers up to 100 W of power to connected devices. The cable handles single 8K at 60 Hz, 5K at 60 Hz or 4K at 60 Hz video output.

Compatibility and Limits

Suitable for users extending a USB4 or DP Alternate Mode port on laptops such as Mac Pro 2020, 2019, 2018, XPS or Chrome Book. Not for buyers whose displays lack DP Alternate Mode on their USB-C input. Not for setups requiring cable runs longer than 30 cm.

40 Gbps Data Rate

The decisive specification is the 40 Gbps maximum data transfer rate. This determines whether the cable can sustain 8K at 60 Hz video and high-speed storage traffic without bottlenecking the link. Verify that both host and peripheral support this bandwidth before purchasing.

Questions about this item

Should I choose the 30 cm length or is a longer version available?

The only length offered is 30 cm. If you need more reach, you will need a different cable.

What does the 40 Gbps rating mean when I plug this into my laptop and monitor?

It is the maximum data rate the cable can carry. Actual speed depends on the host port, the display and any dock in the chain.

How does the USB4 interface limit power delivery and video in practice?

The cable supports up to 100 W at 20 V / 5 A and 8K at 60 Hz, but both require the host and display to support those modes.
