   Nvidia showcases OOI and 256 Gb/s DWDM optical research

   Nvidia showcased two research-stage optical-interconnect technologies at SEMICON West 2026, according to a report republished by 创业邦. Optics-on-Interposer places the optical engine on the silicon interposer to shorten electrical paths, while an eight-wavelength DWDM demonstration transmitted 256 Gb/s over one fiber using eight 32 Gb/s data channels. Nvidia has not disclosed product adoption, commercialization schedules, measured power improvements, or bandwidth-density data.

   NVIDIA Explores Optics on the Silicon Interposer

   At SEMICON West 2026 in San Francisco, NVIDIA researcher Nikola Nedovic introduced Optics-on-Interposer (OOI), a research approach that moves optical engines from the package substrate onto the silicon interposer shared with compute chips. The design shortens high-speed electrical paths with denser interconnects; NVIDIA says it can reduce power use and increase interconnect bandwidth density, but has not disclosed measured results or a commercialization timeline. NVIDIA also presented dense wavelength division multiplexing research using eight wavelengths over one fiber to achieve 256Gb/s of total bandwidth.
