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.

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

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.
