NVIDIA 3.3ft 400GBase Direct Attach Splitter Cable

The NVIDIA MCP7Y60-H001 is a 3.3 foot splitter cable for direct attach applications that converts a single 400 G OSFP port into two 200 G QSFP56 links. It relies on twinax copper conductors in a passive design, so it transports InfiniBand HDR and Ethernet traffic while maintaining signal integrity across its full one meter length.

Because the cable draws no power and produces virtually no heat, it suits dense rack environments where thermal budgets are tight. Technicians can install it like a standard patch cord, without separate transceivers, enabling cost-effective upgrades to high-speed fabrics.

The length and passive construction make this cable a natural fit for short-reach connections within a rack or between adjacent racks. Administrators in high performance computing clusters, cloud data centers, and enterprise networks use it to link top-of-rack switches with servers, storage nodes, and GPU systems that need consistent 200 G bandwidth.

If you need a straightforward way to split a 400 G port without adding complexity, the NVIDIA MCP7Y60-H001 delivers reliable throughput, simple deployment, and low total cost of ownership.
