Ayar Labs›Ayar Labs› offers Optical I/O

Ayar says its Optical I/O combination provides greater bandwidth and lower latency than electrical SerDes plus pluggable optics. The company attributes the difference to moving optical conversion close to compute packages.

The solution page also describes flexible reach and integration into existing system-in-package designs. These are supplier claims about the combined system, and actual gains depend on the deployment architecture.

A 2020 research account described TeraPHY as an in-package optical I/O chiplet integrated into an FPGA multichip package. That demonstration established an early technical component of Ayar’s broader Optical I/O approach.

The current offering pairs TeraPHY with SuperNova and positions the combination for AI scale-up. The technical component’s publication date does not by itself establish a first commercial launch year for the combined offering.

The Optical I/O solution is aimed at teams designing large accelerator clusters rather than at general networking buyers. Ayar describes package-level integration, external light delivery, and optical reach as linked design choices.

Its product material discusses multi-rack AI systems and reference designs at package, board, and rack levels. A buyer still needs to assess compatibility with its processor package, fiber routing, cooling, and light source.

Ayar Labs’ Optical I/O offering combines in-package photonic chiplets with an external multiwavelength light source. The architecture moves data between GPU, CPU, and accelerator packages over optical links.

Its current solution page names TeraPHY and SuperNova as the paired components. Ayar targets AI and high-performance computing systems that need interconnects across packages, racks, and data centers.
