[News] Lumentum, Astera Labs, and Corning to Demonstrate 1060 nm VCSEL-Based PCIe over Optics for AI Rack-Scale Connectivity at the 2026 OCP Global Summit - LEDinside

The 1060nm wavelength selection reveals the real strategic calculus: this is not a simple 850nm replacement but a deliberate optimization at the intersection of VCSEL wall-plug efficiency and fiber attenuation for AI rack-scale links. Astera Labs' pivot from PCIe retimers into the optical domain fundamentally redefines the connectivity layer, directly eroding the moat that copper interconnect incumbents like Amphenol and TE Connectivity built around 224G SerDes reach. Corning's participation is the more telling signal: it positions waveguide and fiber integration, not the laser itself, as the next structural bottleneck. OCP platform endorsement transforms this from a lab demo into a Meta-anchored ecosystem lock-in, where design-in switching costs become prohibitive. Coherent, holding the largest VCSEL market share, will almost certainly field a competing 1060nm solution within 12 months, but the epitaxial process window for this wavelength is only 6 to 9 months, meaning first-mover design wins will be sticky. Within 24 months, if PCIe over Optics enters the OCP reference architecture, copper's share in AI cluster interconnect could compress from roughly 70% to below 40%, triggering a full repricing of the connectivity value chain.
