USB4 8K extension cable for Thunderbolt 4 workflows

This 0.5 metre male-to-female cable extends a USB4 or Thunderbolt 4 connection between a host laptop and an external monitor or eGPU. It requires a separate male-to-male USB4 cable to complete the link. The cable supports DisplayPort Alternate Mode for video output up to 8K at 60 Hz. It is aimed at users who need a short reach extension in a high-bandwidth setup.

Bandwidth and protocol limits defined by USB4 40

The cable carries up to 40 Gbps of data, matching the USB4 4.0 specification. Actual throughput depends on the host controller, the connected device and the male-to-male cable used alongside it. Power delivery reaches 100 W at 20 V / 5 A, so the host charger must supply that profile for full charging speed. Video at 8K 60 Hz also requires the source and display to support the necessary DisplayPort bandwidth.

Gold-plated connectors with braided nylon jacket

The connectors use gold-plated contacts inside an aluminium shell for corrosion resistance and shielding. A braided nylon outer sleeve protects the cable from abrasion and kinking during daily routing. The male-to-female layout solves the problem of a fixed male-to-male cable that falls short by a small margin. No male-to-male cable is included in the package.

Questions about this item

Should I choose the .5 m length or a longer cable for my setup?

The .5 m length keeps signal integrity at 40 Gbps and 100 W delivery; longer runs can reduce both speeds and power.

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

It allows full USB4 bandwidth for 8K 60 Hz video and fast external SSD transfers, provided both host and device support 40 Gbps.

Does the Thunderbolt interface cap the cable at a lower speed?

No, the cable is rated for 40 Gbps and 100 W, matching Thunderbolt 4 and USB4 specifications without reduction.
