A 400Gb/s-per-Lane Form Factor Targets Higher AI Fabric Density While Preserving Pluggable Serviceability. NVIDIA and Cisco announced plans for Ultra-Dense Small Form Factor Pluggable (USFP), an optical module architecture designed for 400Gb/s-per-lane electrical signals and capacity up to 12.8Tb/s. The development extends NVIDIA’s pluggable optics roadmap, targeting higher bandwidth density and power efficiency while retaining the deployment flexibility and serviceability of removable transceivers.
