“We will need much faster interconnects because as models get bigger, and more compute and data is needed to train them, it’s necessary to scale out to many racks worth of machines. Interconnect bandwidth during scale-out is critical to preventing the accelerators from stalling while waiting on network transfers for …

“Ultimately, we want to go to significantly smaller subarray sizes on our radars, towards digital beamforming. Optical I/O is a key to that as we integrate more advanced digital receiver technology into our systems. This could be a big boon for us in other areas where there are even more …
