Scaling AI with Wide, Parallel Interconnects
D
9:40Don BarnetsonGUEST
So if you, if you look at how, um, uh, communications has developed in the industry, so we have these, uh, emitters, these, uh, very high-speed lasers that we use today, and the lasers have a, a native bandwidth up to, say, uh, about 50 gigabits.
D
9:54Don BarnetsonGUEST
If you want to drive them faster than that, then the, um, uh, they, they roll off, you know, as any transmitter does.
D
10:02Don BarnetsonGUEST
And so the way we get past that is we explore all sorts of electrical compensation.
D
10:08Don BarnetsonGUEST
So both on the transmitter side and the receiver side, we're looking to kind of reverse those channel impairments in order to push a 200 gigabit signal across a, uh, a channel that's not really designed to do that.
12:02
So the redu- when you say redundancy, it's just about literally having more physical links, uh, and using them all, uh, l- more equivalent physical links and using them all at the same time? Or tell us a little more about the physical redundancy.
