NVIDIA and Cisco Introduce New Pluggable Optics Form Factor to Scale AI Factories
Cisco and NVIDIA announced plans for USFP, a new high-density 400Gb/s-per-lane pluggable optical module designed to scale Ethernet AI fabrics to 12.8Tb/s of overall capacity. USFP delivers 4x the bandwidth density and roughly 1.3x the power efficiency of current 200Gb/s-per-lane optics, letting AI factory operators add compute without extra network tiers.
