NVIDIA and Cisco Introduce New Pluggable Optics Form Factor to Scale AI Factories
New Transceivers Enable AI Builders to Scale Compute Within the Same Network Footprint While Reducing Networking’s Share of the Power Budget Ultra-Dense Small Form Factor Pluggable (USFP) is designed to be the first module to support 400Gb/s-per-lane electrical signals, enabling capacity up to 12.8Tb/s so AI factory builders can scale Ethernet AI fabrics, while extending […]
USFP as the first module to support 400Gb/s electrical signals per lane, enabling a total capacity of up to 12.8TB/s.|The first planned USFP transistor will pack 16 full-duplex lanes in Octal Small Form Factor (OSFP) class physical sizes.|USFP delivers new bandwidth density while maintaining ease of service, deployment flexibility, and operational simplicity.
NVIDIA and Cisco USFP Optics Target 400Gb/s per Lane, With MGX 1.2 and DSX OS Updates at OCP 2026
NVIDIA and Cisco announced plans today for Ultra-Dense Small Form Factor Pluggable (USFP), an optical module format built for 400Gb/s-per-lane Ethernet in AI fabrics. The first planned transceivers put 16 full-duplex lanes in a footprint about the size of an OSFP module, which works out to 6.4Tb/s per module, and the connector is designed to grow to 32 lanes and 12.8Tb/s. NVIDIA and Cisco say USFP delivers 4x the bandwidth and front-panel densit…
