Just would like to understand what you folks mean,
Do you mean all-optical packet switching, i.e. no OEO but all optical switching
with granularity down to Packet(Cell) level?
So these things are real/in-production nowadays?
Would love to know how do they do that -some ROADMs in a Benes/Clos crossbar?
But they would need to be really tightly timed so they can switch down to cell
level?
