NVIDIA is advancing the following era of simultaneous packaged optics (CPO) expertise with a prototype designed to convey the optical engine nearer to the computing chip. In response to Wccftech, the corporate offered its newest optical integration analysis at SEMICON West 2026 below the theme “Optical Integration for Subsequent Technology AI”, together with optics-on-interposer (OOI) prototypes and dense wavelength division multiplexing (DWDM) expertise.
OOI designs transfer the optical engine instantly from the natural packaging substrate onto the silicon interposer that carries the computing chip. In response to The Elec, this eliminates natural substrates from {the electrical} sign path, permitting alerts to go by way of shorter, fine-pitch interposer connections, doubtlessly growing bandwidth density and lowering energy consumption.
Past OOI, NVIDIA demonstrated DWDM expertise designed to extend knowledge transmission capability on a single optical fiber. In response to Wccftech, the demonstration combines eight wavelengths working at as much as 32 Gb/s every, leading to a complete bandwidth of 256 Gb/s per fiber.
Each applied sciences are nonetheless within the analysis section and no commercialization schedule has been introduced. In response to The Elec, NVIDIA says it’s wanting into potential future merchandise. At SEMICON West 2026, NVIDIA researcher Nikola Nedovic additionally stated that creating environment friendly optical interconnects for future AI techniques would require balancing machine and circuit design tradeoffs whereas addressing thermal administration and packaging challenges.
Seeking to the long run, NVIDIA says it plans to develop its optical interconnect with the Kyber NVL1152 structure to attach eight racks right into a single 1,152 GPU NVLink area to assist the Feynman platform. Wccftech added that Feynman is predicted to reach in 2028.
NVIDIA’s current CPO merchandise and manufacturing ecosystem
Though OOI remains to be in improvement, NVIDIA has already launched CPO into industrial manufacturing. In Could 2026, the corporate introduced that its Spectrum-X Ethernet photonics swap with built-in 200Gb/s SerDes and CPO expertise for the Vera Rubin platform entered full manufacturing. In response to NVIDIA, CoreWeave, Lambda, and Oracle Cloud Infrastructure are among the many early adopters.
NVIDIA has additionally established a producing ecosystem to assist CPO merchandise. TSMC will present silicon photonics manufacturing, and SPIL will deal with chip-scale packaging, meeting and testing, the corporate stated. TFC packages the laser die into modules and performs reliability verification. In the meantime, Foxconn integrates Spectrum-X photonics switches into full community techniques.
Different companions embrace Coherent, Lumentum, and Sumitomo Electrical for exterior laser supply modules. Corning, Senko, Browave for fiber optics and associated elements. As famous by The Elec, Fabrinet was used for cooling and ultimate testing.
