NVIDIA and Cisco announce plans for USFP 400Gb/s-per-lane optical module
Overview
NVIDIA and Cisco announce plans for Ultra-Dense Small Form Factor Pluggable (USFP), a pluggable optical module running at 400Gb/s per lane, with capacity up to 12.8Tb/s.
The companies say USFP gives 4x the bandwidth density and about 1.3x the power efficiency of 200Gb/s-per-lane pluggable modules, so AI factories can scale without adding network tiers. The first planned transceivers will have 16 full-duplex lanes in an OSFP-sized footprint, supporting both switches and SuperNICs, and can expand to 32 or more lanes later. TE Connectivity and Amphenol are building USFP cages, connectors and modules. NVIDIA and Cisco plan to publish an open industry specification through a community-led multi-source project that has not yet started.
