10 月 13 日消息，NVIDIA（英伟达）、Cisco（思科）当地时间昨日宣布携手推出业界首款支持 400Gbps / lane 高速信号的可插拔光模块规范 USFP。

USFP 与 OSFP 光模块尺寸相当，首批产品集成 16 条全双工通道，后续还可扩展至 32 条乃至更多通道，从而实现 12.8 Tb/s 的吞吐量。

USFP 光模块的带宽可达现有 200G / lane 可插拔光模块的 4 倍；而在 400G SerDes 技术的支持下，USFP 的能效是后者的 1.3 倍。

其采用新型二维阵列连接器，其两步插入设计可在模块插入后才接合高速触点，从而减少触点磨损，提高信号完整性，并使插入力更可预测；支持 100W 功耗，简化了交换机设计。
