Overview

Celestial AI enhances hyperscale data centers with its Photonic Fabric™, an optical compute interconnect that improves memory sharing and reduces DRAM requirements by up to 35%. This technology lowers power consumption and increases bandwidth capacity, which is essential for multi-tenant cloud environments. Additionally, it allows for the disaggregation of High Bandwidth Memory (HBM) using optics instead of traditional connections. The goal is to provide advanced optical connectivity solutions that support the demands of Generative AI and complex workloads.
