📝 Dipole Labs: AI-controlled optical circuit switching for AI clusters Today @dipole_labs is launching out of stealth. They build high-speed optical circuit switches for AI data centers. It's quite surprising, but GPUs in a datacenter spend about half their time idle, waiting for data. Between racks data already travels as light through optical fiber. But at every switch it gets converted to electricity and converted back. That burns energy and takes time. Dipole's switch keeps the light…
