Thunderbolt 3 cable for 40 Gbps workflows

This 0.5 m Thunderbolt 3 cable connects two Thunderbolt 3 USB-C devices at up to 40 Gbps. It suits creative professionals and engineers who need short, high-speed links between a host and storage, docks or displays. The passive design keeps the cable light and flexible for desktop routing. It is not for buyers who need longer runs beyond the supplied half-metre length.

40 Gbps passive Thunderbolt 3 link

The cable delivers a certified 40 Gbps data rate over its 0.5 m length using a passive copper construction. Nickel-plated 24-pin USB-C connectors mate securely with Thunderbolt 3 ports. Aluminium-Mylar foil with braid shielding protects signal integrity. This specification decides whether the cable meets the bandwidth ceiling your Thunderbolt 3 chain requires.

Daisy-chain up to six devices

The cable supports daisy-chaining up to six Thunderbolt devices from a single port. It carries dual 4K 60 Hz video streams and provides power delivery for connected peripherals. USB 3.1 Gen 2 devices at 10 Gbps and DisplayPort monitors also operate through the same link. These bundled capabilities reduce the number of separate cables a workstation needs.
