Well, almost… 32GFC is fixed and at the standard has been ratified and the physical specs are moulded in concrete. In addition to this there are functions that enable to combine 4 of these into a single 128Gb link. Yes 128Gb/s. That’s fast….Ohhh wait… thats only ONE WAY which means a single link can push 256Gb/s in total. That allows you to push 25600MB per second through a link. In order to achieve these transmission speeds there has been a somewhat restructuring on the individual requirements w.r.t. quality of the actual link.
