Thunderbolt 4 cable for high-speed workflows

This 2.3 ft Thunderbolt 4 cable connects notebooks, monitors, external GPUs, docks and storage at up to 40 Gbit/s. It supports 8K resolution at 60 Hz and delivers up to 240 W of power for charging laptops and tablets. The passive, plug-and-play design works with MacBook Pro, MacBook Air, iPad Pro, Surface Book, ThinkPad X1 and other Thunderbolt 4 hosts.

Passive length limits bandwidth and power

As a passive cable, the 2.3 ft length is near the practical maximum for maintaining full 40 Gbit/s throughput and 240 W charging without active signal conditioning. Longer passive runs would reduce data rates or power delivery, so this length suits desktop setups where devices sit close together. It cannot extend across a room or through cable trays while preserving peak performance.

Intel Thunderbolt certification guarantees

The cable carries Intel Thunderbolt certification, confirming it meets the official specification for 40 Gbit/s data, 8K video and 240 W power delivery. Non-certified cables may claim similar numbers but often fail compliance testing, causing unstable links or device damage. This certification is the single specification that verifies the cable will work reliably with every supported host and peripheral listed.

Questions about this item

Should I choose the 2.3 ft Thunderbolt 4 cable or a longer one for my dock setup?

The 2.3 ft length suits tight desk runs between a notebook and a Thunderbolt dock; pick a longer cable only if the devices sit farther apart.

What does the 40 Gbit/s rating deliver when I connect an external SSD to my laptop?

You can move large project files at up to 40 Gbit/s, cutting transfer time for multi-gigabyte media compared with slower USB links.

How does the Thunderbolt 4 interface limit real-world charging and display output?

The cable carries up to 240 W Power Delivery and drives an 8K 60 Hz display through DisplayPort Alt Mode, both at the full Thunderbolt 4 spec.
