Certified 40 Gbit/s Thunderbolt 3 Cable

This Thunderbolt 3 certified cable connects Thunderbolt 3 devices with full 40 Gbit/s bandwidth and up to 100 W power delivery. At 0.8 metres it suits desk docking stations and short peer-to-peer links. It also works with USB 3.2 Gen 2 gear at 20 Gbit/s.

Plug-and-play male-to-male USB-C

Both ends are male Thunderbolt 3 USB-C connectors so no adapters are required. Nickel-plated contacts and aluminum-Mylar foil with braid shield resist interference. The PVC jacket is flexible but the 40 Gbit/s rating only holds at this length; longer runs drop to 20 Gbit/s.

40 Gbit/s Thunderbolt 3 data rate

The single specification that decides fit is the 40 Gbit/s Thunderbolt 3 rate over 0.8 m. Buyers who need longer 40 Gbit/s runs or active optical cables cannot use this passive copper link.
