An optical I/O chiplet that carries 8 Tbps between packages in co-packaged AI systems.
What it changes
Replaces copper links and pluggable optics with a chiplet inside the package, changing how far accelerators can sit apart before bandwidth forces a redesign.
Availability
Enterprise only (global)
Access and cost
Get Ayar Labs TeraPHY — Pricing is not published; the roadmap and detailed specifications are released to design partners under NDA.
Evidence it works
- Specifies 8 Tbps bidirectional bandwidth, 10 ns latency and UCIe compliance for the TeraPHY chiplet. — source
- Joined the NVIDIA NVLink Fusion ecosystem in June 2026 to bring co-packaged optics to rack-scale AI infrastructure. — source
What it cannot do yet
- Sold into system designs and under NDA: there is no list price and no way to buy a part directly.
- Specifications are marked preliminary and subject to change, so a design needs margin against a moving part.
