Nvidia and Cisco have introduced a new network interface called Ultra-Dense Small Form Factor Pluggable (USFP) designed to meet the growing data demands of AI data centers. This optical transceiver is the first to support 400Gb/s per lane, with the potential to reach up to 12.8Tb/s in total bandwidth. The USFP module is four times more powerful than traditional 200Gb/s per lane interfaces and offers a 1.3x improvement in power efficiency.
The new interface is intended to scale efficiently, with development steps still pending for reaching its full capacity. Cisco expects the complete USFP module to eventually achieve an overall bandwidth capacity of 12.8Tb/s. The interface is designed to support power dissipation of up to 100 watts without requiring a dedicated cooling circuit.
Nvidia and Cisco have partnered with TE Connectivity and Amphenol to create the remaining components of the USFP networking infrastructure.
