- Joint demo at OCP Global Summit, San Jose, Oct 12-15, booth B34.
- Combines Astera Labs Scorpio Smart Fabric Switch, Lumentum 1060 nm VCSEL platform, Corning multimode fiber.
- Proof-of-concept: multiple 32 Gb/s NRZ optical channels, error-free PCIe-5 link.
- VCSEL arrays use 2D arrays with backside lens technology, built on Lumentum's smartphone 3D sensing manufacturing platform.
- Designed to address reach, cable density, signal integrity, power, and thermal constraints in AI racks.
- Lumentum, Astera Labs, and Corning announced a joint demonstration of PCIe-over-optics connectivity for AI rack-scale architectures at the 2026 OCP Global Summit in San Jose, October 12-15. The rack-level demo combines an Astera Labs Scorpio Smart Fabric Switch with Lumentum's 1060 nm VCSEL-based optical interconnect platform and Corning multimode fiber. The proof-of-concept shows multiple 32 Gb/s NRZ optical channels and an error-free PCIe-5 link, designed to address reach, density, power, and thermal constraints in AI racks.
