GoKawiilNvidia and Cisco introduce USFP optical interface for AI data centers
Nvidia and Cisco have jointly unveiled Ultra-Dense Small Form Factor Pluggable (USFP), a new optical transceiver standard supporting 400Gb/s per lane, the first interface to do so. Cisco says the module is designed to eventually reach total transfer rates of 12.8Tb/s, offering four times the bandwidth of existing 200Gb/s optics and 1.3x better power efficiency. Initial USFP transceivers will have 16 full-duplex lanes and work with both switches and Nvidia's SuperNIC adapters, which move data between GPUs using the RoCE protocol.
