SKU CH-02EA-AARED MPN TBLT4MM50CM

A 50 cm Thunderbolt cable carrying 40 Gbps data, 100 W power and 8K 60 Hz video over USB-C

  • 40 Gbps data transfer for Thunderbolt devices
  • Up to 100W Power Delivery charges laptops
  • Full 8K 60Hz video via DisplayPort 1.4a
  • 50cm length suits compact desk setups
  • Compatible with USB-C devices for charging and sync

What this cable does

This Thunderbolt 4 cable carries 40 Gbps data, full 8K 60 Hz video and up to 100 W of Power Delivery over a USB-C connector. It connects Thunderbolt 3, Thunderbolt 4 and USB4 hosts to docks, displays and storage devices.

The speed that matters

The cable is rated for 40 Gbps, which is four times the throughput of a standard USB 3.2 Gen 2 link. That bandwidth decides whether a single cable can drive an 8K display and move large project files at the same time.

Capacity and limits

At 50 cm the cable reaches across a typical desk setup without excess slack. It powers laptops at 100 W and bus-powered drives at 15 W. Builders needing longer runs or multiple daisy-chained Thunderbolt devices will need a different length.

Questions about this item

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

The cable moves data at up to 40 Gbps between Thunderbolt 4, Thunderbolt 3, or USB4 hosts and devices, so large photo and video libraries transfer roughly four times faster than a 10 Gbps USB 3.2 Gen 2 link.

Which interface standard does the USB-C connector follow, and what does that limit in practice?

The cable uses Thunderbolt 4 over USB-C, capping throughput at 40 Gbps and power delivery at 100 W for charging and 15 W for bus-powered peripherals.

How long is the cable, and will it reach from a desk dock to a laptop on the same surface?

The cable measures 50 cm (1.6 ft), which is long enough for side-by-side devices on a desk but too short to span under a monitor stand or across a workbench.
