19.2Tb is 2 x 9.6Tbps. Some (most) companies count Tx and Rx separately despite it making no sense in the context of serdes lanes. Stupid marketing in my opinion.

I don't think they are meaningfully ahead, it's more to do with what's available at the time. 200/224G is only just coming available this year. The others will have the same in their next product announcements.

Thanks again. Very PS, rad to see you putting commits into mopidy still. I haven't touched mpd like systems in a decade but they have a fond place in my heart!!
