NVIDIA And Cisco Unveil USFP Optical Module Technology Supporting 400Gb/s-per-Lane Connectivity For Next-Generation AI Factories

Key takeaways

• USFP gives AI builders 4× bandwidth density and 1.3× power efficiency over 200 Gb/s optics, letting them scale AI fabrics without extra switch tiers.
• 12.8 Tb/s total capacity
• 400 Gb/s per lane
• 16 full‑duplex lanes

What happened

NVIDIA and Cisco announced Ultra‑Dense Small Form Factor Pluggable, a 400 Gb/s‑per‑lane optical module that doubles lane count and bandwidth compared to current 200 Gb/s optics, enabling 12.8 Tb/s total capacity in an OSFP‑sized footprint.

Why it matters

USFP lets AI factories connect more computing systems without adding extra switch layers, reducing latency, power use and cost per bit. The higher density and power efficiency (≈1.3× better) mean operators can scale AI workloads while keeping infrastructure footprints and energy budgets lower.

Short-term and longer-term

Short-term. Over the next few weeks, traders should watch for early adoption signals from AI‑heavy customers and any pricing announcements.

Longer-term. For investors, USFP represents a strategic move to capture the growing AI infrastructure market.
