Short Thunderbolt cable for high-power devices

This 0.2m Corn Electronics cable carries Thunderbolt 4 and Thunderbolt 3 signals over a USB4 link rated at 40Gbps. It supports single-display 8K at 60Hz or dual-display 4K at 60Hz and delivers up to 240W of USB Power Delivery 3.1 power. The brown cable is aimed at users who need maximum throughput and charging in a very short reach.

Practical limits of the 40Gbps USB4 link

The 40Gbps theoretical ceiling translates to roughly 2.7G/s in real-world transfers, so large file moves will hit that bound. PD3.1 negotiates 48V at 5A for the full 240W, but the source and sink must both support the standard; otherwise the cable falls back to 100W or lower profiles such as 90W, 66W, 45W, 22W or 18W. Display bandwidth is shared with data, so dual 4K@60Hz leaves less headroom for simultaneous storage traffic.

Simple plug-in with one common snag

Both ends are standard USB-C connectors, so installation is a matter of plugging into any Type-C port on a MacBook, iPad Pro, Switch, Thunderbolt dock or Type-C monitor. The only frequent issue is that some host ports only implement USB 3.2 or USB 3.1 speeds, which caps throughput well below the cable’s 40Gbps rating. The 0.2m length also means the cable cannot bridge devices that are further apart.

Questions about this item

Should I choose the 0.2 m brown cable or a longer length?

The 0.2 m brown cable is the only length and colour offered; it is ideal for keeping a desk tidy when the host and peripheral sit side by side.

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

The 40 Gbps rating lets you drive a single 8K display at 60 Hz or two 4K displays at 60 Hz without compression.

How does the USB4 and Thunderbolt 4/3 interface limit real-world speed and power?

The cable is certified for USB4 and Thunderbolt 4/3, delivering up to 2.7 G/s data throughput and 240 W (48 V / 5 A) charging under the PD 3.1 spec.
