Nvidia has started volume production of its Spectrum X copackaged optics Ethernet switch to eliminate data bottlenecks in artificial intelligence clusters. At GTC Berlin, Chief Executive Jensen Huang confirmed a $1.1 billion capacity advance to chip testing firm KYEC to establish dedicated facilities in the United States. The investment anchors a broader supply chain expansion that locks in optics, substrate, and testing agreements through 2028.

Bandwidth limits in large scale GPU clusters are forcing a direct shift from electrical wiring to optical interconnects. The Spectrum X switch relies on the COUPE manufacturing process created alongside TSMC to place silicon photonics directly adjacent to compute silicon. This architecture shortens the circuit board electrical route, preserving signal strength during high speed transfers. Nvidia is working with ASE subsidiary SPIL to expand optical engine assembly in Taiwan, targeting a 15x output increase by 2027 and a 30x increase by 2028.
Hardware scaling requires simultaneous upgrades across post fab production steps. The $1.1 billion advance to KYEC funds construction and equipment for an advanced testing site in the United States, targeted for high output in 2027. Nvidia plans to double its worldwide testing volume across operational centers in the United States, Taiwan, and Singapore. Substrate providers Unimicron, Ibiden, and Samsung Electro Mechanics will expand delivery capacity by 2.5x over the next 3 years, while Amkor increases interposer wafer capacity in South Korea by more than 300% by 2028.
Infrastructure expansions align with vehicle and robotics deployments powered by the Vera Rubin platform. Automakers Mercedes Benz, Volvo, Jaguar Land Rover, and Volkswagen Commercial Vehicles are adopting the Hyperion architecture for upcoming vehicle production lines. Nvidia also partnered with Agile Robotics to release an open reference humanoid robot early next year, combining preconfigured processors and operating runtimes to lower software development barriers.
Precision manufacturing vendors in Taiwan are logging long delivery schedules to support these optical packaging targets. All Ring Tech holds equipment orders extending into 2027, with machinery delivery times stretching to 8 months for automated optical alignment and glue dispensing systems. FitTech is preparing test equipment for photonic integrated circuits to screen silicon dies before packaging begins. Motion control specialist GMT Global supplies positioning platforms delivering alignment accuracy within 50 nanometers across 8 to 12 inch optical wafers.
