Astera Labs

Overview

Astera Labs is a purpose-built connectivity IC company designing retimers, switches, and smart cable modules for rack-scale AI infrastructure. The company's product portfolio spans four protocol families: PCIe (Aries retimers), CXL (Leo smart memory controllers), Ethernet (Taurus DSP retimers), and UALink/NVLink (Scorpio AI fabric switches). Astera Labs positions itself as the connectivity foundation for open rack-scale architectures, enabling the shift from server-level to rack-level computing with 32-128+ GPUs operating as a single system.

With PCIe Gen 6 retimers shipping in high-volume production at multiple hyperscalers while competitors remain at early evaluation, Astera Labs has established a significant lead in next-generation connectivity silicon.
