Celestial AI offers a photonic interconnect platform called Photonic Fabric. The technology uses light instead of traditional copper-based electronic interconnects to move data, which is designed to support high bandwidth and nanosecond-level latency.

The platform is built for AI data centers and hyperscale cloud providers. It supports the scaling of AI compute within packages and across multiple racks, which may help in handling larger model sizes and increasing context lengths for inference.

Buyers should note that this is a technical infrastructure solution. As the company has been acquired by Marvell Technology, prospective users should confirm how the Photonic Fabric integrates into Marvell's connectivity portfolio.

Key product forms include PFLink for connectivity, PFSwitch for scale-up switching, and OMIB for die-to-die interconnects within a package.

Key Features
