400G to 2×200G High-Performance Breakout DAC
NADDOD Q2Q56-400G-DAC is a high-performance direct-connect copper cable that supports the efficient splitting of a single QSFP-DD 400G port into two independent QSFP56 200G links. Designed for short-distance, high-bandwidth, low-latency data center interconnect scenarios, it complies with IEEE 802.3 and QSFP-DD/QSFP56 MSA specifications. Passive DAC cables offer the lowest-cost, lowest-latency, and near-zero-power high-speed connection currently available. Supporting hot-swapping and compatible with mainstream device platforms, it can connect multiple DGX Spark nodes to a 400G switch, thereby building a compact desktop-level AI cluster.
It is widely used in high-density, short-distance interconnect environments such as high-performance computing, AI and RoCE networks, and cloud data center ToR/Leaf architectures, and provides a flexible and scalable physical layer foundation for smooth upgrades to future 400G networks.
Based on the Spine-Leaf architecture, upgrading from 200G to 400G using NADDOD optical connectors can help customers reduce network costs, improve data transmission speed, and enhance data processing capabilities.
The Q2Q56-400G-DAC passive DAC cable is deeply optimized for AI cluster interconnections and high-density data center environments, delivering extreme performance and flexibility. Ideal for short-range (≤3m) intra-rack or adjacent-rack connections, it simplifies cabling complexity and supports dense deployments.
