AI Drives Need For Optical Interconnects In Data Centers

Celestial AI has an optical interconnect solution, as well, which the company claims is more thermally stable than the ring resonators currently used in transporting optical signals, and which should allow closer communication with ASICs. “We’re providing optical connectivity all the way to the point of compute,” explained Celestial AI CEO David Lazovsky. “A lot of the companies that are in the co-packaged optics space work on a wire-forwarding technology, meaning you send me a signal electronically and all I’m going to do is convert that to optics and drop it off in an electronic signal at the other end of the fiber. At Celestial AI, we are a full stack solution. We have a protocol adaptive layer to provide compatibility with our customers’ existing infrastructures.”
