Lumentum Holdings Inc., Astera Labs, Inc., and Corning Integrated immediately introduced a joint demonstration of PCIe-over-optics connectivity for AI rack-scale architectures on the 2026 OCP World Summit in San Jose, California. The rack-level demonstration combines Astera Labs Scorpio sensible cloth switches with Lumentum’s 1060 nm VCSEL-based optical interconnect platform and Corning multimode fiber connectivity. This demonstration might be accessible for viewing at Astera Labs sales space #B34 from October twelfth to fifteenth.
This demo presents a totally operational optical hyperlink that makes use of VCSEL transmitters and photodetectors to increase PCIe connectivity inside an AI rack. By transporting PCIe over many parallel optical channels, this structure is designed to handle the attain, cable density, sign integrity, energy, and thermal constraints that may restrict conventional electrical interconnects as rack-scale AI methods develop.
The optical interconnect makes use of a high-density 1060 nm VCSEL and a photodetector array carried out in superior packaging, together with a two-dimensional array with back-lens expertise. Constructed on Lumentum’s ultra-high quantity platform in 3D sensing for smartphone gadgets, it’s designed to assist excessive bandwidth density, robust sign integrity, and environment friendly optical connectivity for rack-level AI architectures.
Astera Labs’ Scorpio Sensible Material Swap supplies an illustration switching aspect to display how optical connectivity can lengthen attain inside rack-scale AI methods whereas sustaining a PCIe-based structure.
This proof-of-concept system is designed to display a number of 32 Gb/s NRZ optical channels over Corning multimode fiber and error-free PCIe-5 hyperlinks. This configuration combines a high-density Lumentum optical engine with Astera Labs’ Scorpio sensible cloth switches in a rack-representative system association.
“AI infrastructure is bringing optical connectivity nearer to computing methods, with attain, density, and energy turning into main challenges,” stated Matt Sysak, chief expertise officer at Lumentum. “This demonstration with Astera Labs and Corning reveals how Lumentum’s 1060 nm VCSEL platform can develop PCIe connectivity and unlock a complete new class of capabilities.”
“As AI clusters scale to unprecedented ranges, we’re breaking the constraints of single-rack-level architectures,” stated Adit Narasimha, senior vice chairman of the Sign Connectivity Group at Astera Labs. “This demonstration reveals how VCSEL-based front-end optics are enabled by Astera Labs’ Scorpio sensible cloth switches and COSMOS hyperlink intelligence to cut back latency, enhance energy effectivity, improve bandwidth density, and overcome connectivity bottlenecks between rack-scale AI methods.”
“As optical hyperlinks transfer nearer to computing gadgets, fiber connections should assist elevated density, precision, and scalability,” stated Claude Echahamian, vice chairman and common supervisor, rising enterprise and EMEA, Corning Optical Communications. “Corning’s multimode fiber options and industry-leading MMC connectivity allow this demonstration and assist assist the evolution of high-density optical interconnects for AI infrastructure. As AI clusters proceed to develop in dimension and complexity, Corning is dedicated to growing fiber and connectivity applied sciences that allow new computing networks and sensible cloth architectures.”
