Question about Delock Thunderbolt 3 cable

As far as I know, Thunderbolt 3 cables have data throughputs of up to 40 Gbits per second... Why does it only say 20 Gbits? 20 Gps would only be Thunderbolt 2?! Many thanks for the clarification:-)

Hello, I know the question is older, but I'll write what I know anyway.

As far as I know, with standard Thunderbolt 3 cables the full data rate (40 Gbit/s) can only be transmitted over very short distances (about 0.5 to 0.7 m). If longer cables are produced with this standard technology (e.g. 1 or 2 metres), the data rate drops. Some of these are also called passive cables.

In the meantime, there is also the possibility of producing Thunderbolt 3 cables with 40 Gbit/s, which are e.g. 1 or 2 metres long. However, these cables contain active additional technologies, which makes them more expensive than the standard cables. These cables are sometimes called active cables. An example of such a cable is this one: StarTech 1M THUNDERBOLT 3 40GBPS CABLE

Before buying a cable, it is probably worth taking a quick look at the specifications from the manufacturer (for the Startech cable, see here: https://www.startech.com/ch...), as the two cable types differ in features.

The (passive) Delock cable can only transmit Thunderbolt 3 at 20 Gbit/s, but it can also transmit USB 3.1 at 10 Gbit/s. The (active) Startech cable can transmit USB 3.1 at 10 Gbit/s. The (active) Startech cable can transmit Thunderbolt 3 at 40 Gbit/s over a length of 1 m, but only USB 2.0 at 480 Mbps.

This means that depending on the application, it is better to use one or the other cable.

The manufacturer also states the following information on their website "Thunderbolt™ 3 up to 20 Gb/s."
