2D FAUs sit at the point where optical fibers meet two-dimensional photonic devices — the interface that AI-scale interconnect density now depends on.
Couple fiber to VCSEL and photodiode arrays inside CPO modules, where optical I/O moves onto the package next to compute silicon.
High-fanout optical links for 800G and 1.6T interconnect across training and inference fabrics, where density scales with model size.
Board- and system-level optical routing where dense 2D fiber terminations replace electrical traces over distance.
As AI systems scale, optical interconnect moves from the rack edge toward the package. That migration raises channel density per unit area — and two-dimensional coupling becomes a requirement rather than an option.
The micro-optical component market that serves this transition is evolving from conventional single-row arrays toward 2D arrays, driven by co-packaged optics roadmaps and the bandwidth-per-package needs of accelerators and switches.
Suppliers with working 2D FAU capability today can be designed into CPO roadmaps early — a durable position as volumes scale.
Precision that is repeatable and manufacturable — not just achievable in the lab — is what separates a prototype from a supplier.
Joint development from specification through qualification builds the trust and shared roadmap that strategic accounts require.
