Nvidia Spectrum-X CPO Ethernet Switch Enters Full Mass Production with Fivefold Power Cut
Nvidia announced in the early hours of August 14, 2026 that its Spectrum-X Ethernet silicon-photonics switch has entered full mass production. Built on the Spectrum-6 chip with co-packaged optics, the system cuts laser count by fourfold and power consumption by fivefold while improving mean time between failures tenfold, making it the world's first 200G/lane CPO Ethernet switch in volume production. Tianfu Communication supplies laser module subassembly for the system. Separately, Focuslight Technologies reported new customers for its NPO/CPO micro-optics and high-channel V-groove products in the first half of 2026, with a technology licensing agreement with a major customer now under execution.
Nvidia announced in the early hours of August 14, 2026 that its Spectrum-X Ethernet silicon-photonics switch has entered full mass production. The product is built on the next-generation Spectrum-6 switch chip and employs co-packaged optics (CPO) technology, reducing the laser count by fourfold, lowering power consumption by fivefold, and improving mean time between failures by tenfold. Nvidia described it as the world's first 200G/lane CPO Ethernet switch system to reach volume production.
