Chapter in this post:
Since I am currently using a Thunderbolt monitor from LG (LG 29UC97-S - as an alternative to the Thunderbolt monitor from Apple) that supports Thunderbolt 2, the question arose whether you can use an older (approx. 2-3 years old) Thunderbolt cable or whether you can use it to set the speed to Thunderbolt 1 limited, as the cable does not yet support Thunderbolt 2 (20 GBps).
I have some forums for this (e.g. the Apple support forum) and came across the following information:
There are both Apple and DeLock TB cables on Amazon. I couldn't find any other manufacturers in the offer. And the cables from DeLock and Apple do not have a large price difference (currently approx. 6 to 7 EUR with a total price of around 40 EUR). This is partly because there is electronics in every TB cable and partly because other manufacturers have to pay Apple license fees if they have to bring Thunderbolt cables to market.
Nevertheless, for the sake of completeness, here are the links to the two offers:
I also did a little research on the website thunderbolttechnology.net read. Thunderbolt 3 (the 6th generation) is already being presented there, which is going into the ring as an alternative to Apple's USB-C. With 40 GBps, the transmission speed of Thunderbolt 2 is doubled again. However, I cannot say how it behaves with the cables in Tunderbolt 3.
It could be that the electronics that are in the cable will be revised here as well. The old cables seem to be fundamentally compatible, because the plug still looks the same.
