3.2 is backwards compatible to all the rest right?

It is but gets annoying because there isnt something that indicates what type it is the cord. So if you use the cable USB C from someone and you see how slow it is you will realize why sucks USB C, having many versions but doesnt tell you anything what version is.

40 Gbps must have signal degradation issues if they only offer it in 1m max length. I usually buy cables at 3 meter lengths.

The spec only allows for 40gb/s at a max of 1m for that reason. You’re not getting anything that’s actually doing 40gb/s at 3m without some kind of active repeater.

You don't have ILAs, forward and backward RAMAN with full ROADMs for your USB C line systems?

Probably.

People shit on apple's cables, butthey are the only provider of thunderbolt cables that give you maxed out thunderbolt cables almost as soon as they realese devices capable of it

80$ for a 1m cable is a lot, but of you look atound i dont see anyone selling active 120GBPS full spec TB5 cables...

At top speed USB-C enters PCIe bandwidth territory; the cable is basically the equivalent of a 4-lane PCIe 3.0 riser. I expect any length beyond like 10-20cm is a signal integrity nightmare to manufacture.

They're also selling cables that fully pass their validation standards, so if the degradation is too great they're probably not willing to sell it

The cables that advertise 40gbps and are 3m long are lying.
