MCP7Y40-N001, NVIDIA Mellanox NVIDIA Splitter Cable, 800Gb/s IB NDR Twin Port/4x200Gb/s/OSFP to 4xQSFP112/1m

The Mellanox MCP7Y40-N001 is a high-performance InfiniBand NDR passive copper splitter cable designed for modern data center and high-performance computing networks. This accessory connects NVIDIA Quantum-2 NDR InfiniBand switches to servers or downstream switches using an OSFP twin-port 800G interface on one side and four QSFP112 200G interfaces on the other. With a total bandwidth of 800 Gb/s (twin port), the MCP7Y40-N001 is ideal for dense rack deployments in Asia, Europe, Africa, and North America where operators need short-reach, low-latency connectivity between switches and nodes. The 1 m passive copper, direct attach design helps reduce power consumption and latency compared with active optical solutions, making it well suited for cost-sensitive rollouts by distributors, small and medium integrators, and large end users.

The MCP7Y40-N001 supports InfiniBand NDR technology, enabling high-speed switch-to-node or switch-to-switch links inside clustered computing, cloud infrastructure, and research environments. Its 1x OSFP twin-port NDR 800G to 4x QSFP112 200G split configuration allows you to fan out one high-capacity port into four independent 200G links, simplifying cabling and improving port utilization on NVIDIA Quantum-2 platforms. Because this cable is passive and direct attach, it offers predictable performance and straightforward installation in top-of-rack, end-of-row, or spine-leaf architectures. For integrators, the standardized OSFP and QSFP112 interfaces help streamline BOM planning and multi-site deployment across different regions.

Designed for selected NVIDIA Quantum-2 NDR InfiniBand platforms that support OSFP to QSFP112 splitter cables, the MCP7Y40-N001 provides a reliable, vendor-aligned option that reduces interoperability risks during upgrades or new builds. Distributors can use this model to complete NDR switch and adapter bundles, ensuring that customers receive a fully compatible connectivity path from day one. For end customers running AI training clusters, research computing, or large-scale virtualized workloads, the cable’s 800 Gb/s twin-port bandwidth and low-latency copper design help maintain consistent performance between compute nodes and core fabric switches. Whether you are expanding an existing NDR fabric or starting a new deployment, the Mellanox MCP7Y40-N001 offers a straightforward way to achieve high-speed InfiniBand connectivity with minimal complexity.
