Nvidia and Cisco launch 400Gb/s USFP transceiver for AI data centers
Nvidia and Cisco introduced the Ultra-Dense Small Form Factor Pluggable (USFP) transceiver, a next-gen optical interface for data centers. The module supports 400Gb/s per lane, with a total capacity of up to 12.8Tb/s—four times faster than 200Gb/s interfaces—while improving power efficiency by 1.3x. It is designed for AI workloads, scaling via 16 full-duplex lanes in an octal form factor, with…
Key points
- USFP supports **400Gb/s per lane**, with a max total of **12.8Tb/s**—four times faster than 200Gb/s interfaces
- First versions use **16 full-duplex lanes**, with future scaling to **32+ lanes** for AI workloads
- Third-party partners like **TE Connectivity** and **Amphenol** supply modules, connectors, and cages
Cisco notes the USFP’s two-step insertion design reduces wear and improves signal integrity, handling up to 100 watts without dedicated cooling. While full 12.8Tb/s capacity remains a future goal, the first versions will support 1.6Tb/s endpoints without adding network tiers. The companies emphasize its role in AI-driven data center growth, though Cisco acknowledges it fits into a broader mix of optical architectures.
