These things don't go to a single system. The signal is optically split at the ends and there are big racks of transceivers, each transceiver deals with a single mode. With 55 modes you are looking at dealing with 27 terabits or 125 terabytes per second on any given system.

I get 28.5 Tib/s, so 3.6 TiB/s, not sure how you went from 27 to 125?

I am also not sure, it's not even a case of multiplied instead of divided. Bizarre.
