Cross-cutting opportunities (industry read)

• PCIe Gen5/Gen6 & CXL Retimer / Switch IC — Hyperscale AI racks need PCIe Gen5→Gen6 + CXL retimers/switches just to keep host-to-accelerator links alive at scale; this is Astera Labs' core ALAB-listed business.
• 800G / 1.6T Co-Packaged Optics & Silicon Photonics module — Scale-out beyond ~100K GPU clusters (verified Colossus class) is bandwidth-bound; pluggable optics are hitting reach/power limits, so the industry is racing to ship CPO at 800G→1.6T while still selling AEC for short reach.
• UALink AI Scale-Up Fabric (GPU-to-GPU) — NVLink lock-in is the single biggest non-NVIDIA accelerator pain point; the UALink consortium is the answer and Astera is the first merchant silicon making it ship-worthy.
