NVIDIA announced its Spectrum-X Ethernet co-packaged-optics (CPO) switch has entered full mass production, calling it the industry's first 200G/lane CPO Ethernet switch system. The hardware is manufactured through a Taiwan-anchored supply chain spanning TSMC, SPIL, Lumentum, TFC and Foxconn.
What does the Spectrum-X mass-production announcement mean for the industry?
NVIDIA has moved its Spectrum-X Ethernet co-packaged-optics switch into full mass production, positioning it as the first 200G/lane CPO Ethernet switch system to reach that stageCITE:E1. The announcement, dated August 15, 2026, marks the transition of the architecture NVIDIA first previewed with named partners back in March 2025 from prototype to shipping productCITE:E1.
What performance advantages does the CPO switch offer over conventional designs?
NVIDIA states the Spectrum-X CPO switch delivers a 5x improvement in network power efficiency, a 5x increase in uninterrupted AI application runtime, and up to a 10x extension of mean time between failures (MTBF)CITE:E2. All three figures are presented by NVIDIA as comparisons against its prior, non-photonic switch designsCITE:E2.
How do the SN6810 and SN6800 differ in specs and use cases?
NVIDIA is shipping two Spectrum-X CPO switch models with different chassis sizes, ASIC counts and port configurationsCITE:E8. The SN6810 fits into a 2U liquid-cooled chassis with 128 ports of 800 Gb/s, for 102.4 Tbps of total capacity, while the SN6800 stacks four ASICs in a 5U system for 409.6 Tbps, supporting 512 ports of 800 Gb/s or over 2,000 ports of 200 Gb/sCITE:E9.
| Spec | SN6810 | SN6800 |
|---|
| Chassis | 2U, liquid-cooled | 5U |
| ASIC count | 1 | 4 |
| Total switch capacity | 102.4 Tbps | 409.6 Tbps |
| Port configuration | 128 × 800 Gb/s | 512 × 800 Gb/s, or 2,000+ × 200 Gb/s |

What roles do TSMC, SPIL, and Foxconn play in the Spectrum-X supply chain?
TSMC (台積電) manufactures the advanced silicon-photonic chips, SPIL (矽品), an ASE Technology (日月光) unit, handles wafer-level and chip-level packaging and test, Lumentum and TFC (天孚通信) supply laser chips and module subassemblies, and Foxconn (鴻海) develops and assembles the complete switch systemCITE:E5. This division of labor was first disclosed earlier: at NVIDIA's GTC event in March 2025, the company named TSMC (2330), Foxconn (2317), ASE Technology's SPIL unit (3711) and 波若威 (3163) as Taiwan partners for the Spectrum-X and Quantum-X CPO switch linesCITE:E11.
How does Spectrum-XGS extend AI networking beyond a single data center?
NVIDIA's Spectrum-XGS technology extends the Spectrum-X network architecture across an entire building or campus, linking multiple data centers into a single coordinated systemCITE:E6. NVIDIA says the technology stays compatible with open-source tools such as SONiC while increasing AI network transmission speed by 1.6xCITE:E6.
How are Taiwan supply-chain firms' AI revenue share and capacity expansion trending?
Three Taiwan supply-chain firms named alongside NVIDIA's Taiwan partner list report rising AI-linked business, though these figures describe their overall AI/HPC exposure rather than Spectrum-X-specific revenue. King Yuan Electronics (京元電) said its 2025 AI-related business is expected to exceed a 20% share of total operations, citing advanced-process demand and AI-driven demand for high-end chips and packaging/testCITE:E12. WinWay Technology (旺矽) said it is expanding capacity to meet customer demand, with second-half capacity able to increase by 30%CITE:E13. Ying Wei (穎崴) said its AI- and HPC-related applications accounted for 52% of its full product-line revenue in 2024, with the company expecting that share to keep growing in 2025CITE:E14.
| Company | Metric | Value | Period |
|---|
| King Yuan Electronics (京元電) | AI-related business share | >20% | 2025 (company projection) |
| WinWay Technology (旺矽) | Capacity increase | +30% | H2 (company projection) |
| Ying Wei (穎崴) | AI/HPC revenue share | 52% | 2024 |
What does this mean?
The roughly 17-month gap between NVIDIA naming TSMC, Foxconn, SPIL and 波若威 as CPO switch partners at GTC in March 2025CITE:E11 and NVIDIA's August 2026 mass-production announcementCITE:E1 spans the same period in which King Yuan Electronics, WinWay Technology and Ying Wei were separately projecting or reporting AI-related revenue shares above 20%, capacity growth of 30%, and AI/HPC shares of 52%CITE:E12CITE:E13CITE:E14. The evidence pack does not attribute those revenue and capacity figures specifically to Spectrum-X volume, so the two threads — NVIDIA's photonic-switch supply chain and Taiwan suppliers' broader AI business growth — are documented in parallel rather than as a direct causal link.
