As artificial intelligence models continue to expand in scale, the demand for network bandwidth within data centers is surging. On October 12, 2026, NVIDIA and Cisco jointly announced the development of a cutting-edge, high-density pluggable optical module, the USFP. This innovation is designed to bolster the internal network connectivity of AI data centers, facilitating the transmission of greater data volumes within confined equipment spaces while simultaneously curbing network communication energy consumption. Looking ahead, this technology is projected to achieve a total bandwidth of up to 12.8Tbps. When compared to existing optical modules utilizing 200Gbps per-channel technology, the USFP is expected to quadruple bandwidth density and enhance energy efficiency by roughly 30%.
