It's sort of interesting to think about how you would feed this with data.
So if there's a router box that on one side has the optical link that can transfer 1.8 pbit/s out then what's on the other side to get the data into the box? 180k 10gbit ethernet ports? Well, obviously not, so there would be ... 180 10 Tbit/s optical links?
And what would be the processor that could multiplex at that data rate?
If the latest intel 6.0ghz processor coult push out one cache line worth of data for each cycle, that would mean you need (1.8 * 10^15) / (64 * 6 * 10^9 * 8) = 586 of these processors!
Could some custom silicon handle this or would you need some optical processing?
Wild stuff.
- themoonisachees 3y agoAll the processing is necessarily done in photonics for these record transmissions. Even so, these kind of speeds are still impressive for photonics. To answer your question more adequately, nothing is pushing out the data in or recieving it beyond a counter and an application-specific photonics chip that is able to process the frames enough to count them. Anything else assumes levels of processing that would make anyone interested in compute fight over it.
- terryf 3y agoRight - I get it that in the experiment there was no real data being delivered, but trying to consider how one would implement it in an actually useful device for me puts the speed into context. It really is incredible.
