Celestial AI to exhibit “Photonic Fabric” optical interconnect platform at OFC


The company says its technology offers breakthrough optical interconnect for memory and compute to address AI requirements

Celestial AI, a company focusing on AI infrastructure, has announced that it will be showcasing its “Photonic Fabric” during the 2024 Optical Fiber Communication (OFC) Conference, to be held from 25-28 March at the San Diego Convention Center.

The company says its product provides breakthrough optical interconnect for memory and compute to meet the increasingly challenging requirements of AI workloads. According to Celestial AI, its technology addresses the most critical performance chokepoints for advanced AI models, delivering over 25 times greater bandwidth and memory capacity while reducing latency and power consumption by up to an order of magnitude compared to existing copper and optical interconnect alternatives.

The company says its Memory Fabric is the only solution available today that shatters the “Memory Wall,” offering tens of terabytes of optically scalable memory capacity, supporting current HBM3e and future HBM4 bandwidth and latency requirements. It adds that the Compute Fabric enables clusters of hundreds of GPUs or AI accelerators to be optically interconnected with industry-leading bandwidth at extremely low latency and energy consumption.

Celestial AI’s participation at OFC includes a workshop on “Integration of Silicon Photonic I/Os under a High-Power ASIC,” a panel on “Next-Generation Disaggregated Data Centers Using Future Chip to System Photonic Technologies,” and a special event that asks: “How Much Optics Does AI Need?”
