NVIDIA and Cisco Launch New Pluggable Optical Module Form Factor to Expand AI Factories

36KrOctober 12, 20261 min read

NVIDIA and Cisco have jointly launched a new pluggable optical module form factor, USFP (Ultra Small Form-factor Pluggable), designed to expand the scale of AI factory networks. USFP is the first module supporting 400Gb/s per lane, with a maximum single-module capacity of up to 12.8Tb/s, enabling AI builders to connect more compute systems without adding network layers while reducing power consumption per bit transmitted. Compared to existing 200Gb/s-per-lane optical modules, USFP offers four times the bandwidth density and 1.3 times the energy efficiency. NVIDIA and Cisco are collaborating with TE Connectivity and Amphenol to build a multi-source hardware ecosystem around USFP.
