I wonder if that's a typo though. 200G ethernet does exist, as part of the "Terabit Ethernet" standard, but it's extremely rare and you'd have trouble finding anything to connect it to that could negotiate that fast.

Switches are crazy expensive but optics are easily available... here's a 400G for less than $500

200G switches are about the cost of a small car, but if your buying this thing that is probably not a showstopper:

I think it’s just a typo.

It's not "extremely rare" in the intended market. It'll still take you over 2 hours to fill this, if you manage to saturate both links (which you can't realistically do).

Doesn't most vendors sell switches capable of that?

100/200/400Gb is widespread in high-performance (HPC or big AI) datacenters.

Isn't 200G starting to become reasonable common for high-end enterprise gear?

Dual-port 10G/25G is fairly standard on servers these days, and SANs with multiple 100G ports aren't exactly rare either. I wouldn't be too surprised to see 200G or 400G ports on newer spine switches these days.
