MCP7Y70-H002, Mellanox NVIDIA Passive Copper Splitter Cable, 400(2x200)Gbps/4xQSFP56/2m

The Mellanox MCP7Y70-H002 is a high-speed passive copper splitter cable designed for modern data center and cloud infrastructure. As a 400(2x200)Gbps to 4x100Gbps OSFP to 4xQSFP56 breakout DAC, it helps operators, integrators, and enterprise users build efficient short‑reach links inside racks and between adjacent racks. This Mellanox direct attach cable is optimized for high‑density NVIDIA Networking platforms in Asia, Europe, Africa, and North America, where predictable latency and low power are critical. With one OSFP dual‑port interface on the switch side and four QSFP56 connectors on the server or leaf side, the MCP7Y70-H002 allows you to aggregate or distribute 400 Gb/s capacity with simple plug‑and‑play deployment.

The passive copper, direct attach design provides very low latency and removes the need for optical modules and separate fiber cables, which reduces both cost and complexity for distributors and small system integrators. The 2 m length is ideal for typical intra‑rack and row‑based layouts, avoiding excess slack while still giving enough reach for flexible routing. The fin to flat cable jacket style combines a high‑density fin profile at the switch with flat legs on the host side, improving airflow and cable management in crowded racks. This makes the MCP7Y70-H002 suitable for high‑performance computing, AI clusters, storage networks, and leaf‑spine fabrics where cable density and serviceability matter.

For end users running latency‑sensitive workloads, the 400 Gb/s aggregate data rate on the OSFP side with breakout to four 100 Gb/s QSFP56 ports ensures predictable bandwidth between switches and servers. The cable is tailored for short‑reach intra‑rack and rack‑to‑rack high‑speed interconnect, supporting scale‑out designs without adding additional active components. Whether you are refreshing an existing 100G infrastructure or expanding to 400G in stages, the MCP7Y70-H002 lets you connect new high‑capacity switches to existing 100G endpoints in a controlled and cost‑effective way. Distributors benefit from a standard, vendor‑aligned Mellanox part number, while integrators gain a reliable building block for repeatable data center designs across global projects.
