Photonic Fabric Technology: the key to the optical revolution for AI
Celestial AI became known thanks to its patented technology called Photonic Fabric, a major innovation in the field of interconnections.
This photonic fabric uses miniaturized lasers and optical circuits to replace traditional copper cables, thus offering unprecedented performance:
- Very high bandwidth: up to 16 Tbps, multiplying transmission capacity severalfold compared to traditional solutions.
- Near-zero latency: delays on the order of nanoseconds, ensuring instantaneous communication between partner chips.
- Extended distances: components can be positioned farther apart without signal loss.
This technology is all the more critical as current artificial intelligence models are increasingly large and complex. They require an ultra-fast and reliable optical network to exchange massive datasets in real time between different units and avoid bottlenecks.
- Concrete example:
- Amazon Web Services data centers have already praised this advance, announcing that Photonic Fabric connectivity will accelerate their AI deployments.

Thanks to this technology, optical connectivity becomes a fundamental element that should transform the architecture of data centers in the coming years by making the construction of massive neural networks without compromise possible.
Limitations of copper connections and urgency of optical connectivity in AI architectures
Copper, a fundamental material for many interconnections in electronic infrastructures until now, reveals its limits against the growing demands of modern AI systems.
These constraints mainly relate to:
- Limited maximum throughput: the transfer capacity of copper cables quickly plateaus, failing to keep pace with continuous data growth.
- Restricted distance: beyond short distances, signal quality deteriorates, forcing physical proximity of components and thus limiting architecture scalability.
- High energy consumption: copper induces significant thermal dissipation impacting data center power usage.
Modern AI architectures require, however:
- Interconnected networks at very high speed to adapt to massive and parallel processing
- Modularity allowing easy proximity adjustment of computing units according to evolving needs
- Unfailing transmission reliability and stability
Optical connectivity offers an adequate response to these challenges: light pulses pass through fibers designed to carry very high information loads without notable degradation. Marvell and Celestial AI thus propose a solution capable of integrating this technology on a large scale, paving the way for a new era of AI performance.
