SpeedyFiber 0.4M 400G QSFP112 DAC Cable for NVIDIA DGX Spark / GB10 Systems

The 400G QSFP112 Direct Attach Copper (DAC) Cable is designed for 400Gbps Ethernet links using passive copper twinax cable. Each end integrates eight full-duplex copper channels, delivering high bandwidth with ultra-low latency and ultra-low power consumption on the cable itself. Available in 26 AWG and 30 AWG options, the cable supports link lengths up to 2 meters, making it ideal for short-reach rack-to-rack and top-of-rack switch connections. Fully compliant with IEEE 802.3ck, QSFP112 MSA, and InfiniBand NDR standards, this cost-effective and hot-swappable DAC solution simplifies cable management and reduces total power draw in high-density environments. Ideal for cloud computing, hyperscale data centers, and supercomputing environments that require reliable, low-cost, short-distance high-speed interconnects.
