NVIDIA 400Gbs to 2x200Gbs OSFP to 2xQSFP56 Active Fiber Splitter Cable

The NVIDIA MFA7U10-H010 is a 400 Gbit/s active optical splitter cable that lets you turn one OSFP port into two independent 200 Gbit/s QSFP56 links. It arrives as a single, integrated assembly, so there is no need for separate transceivers or patch cords. Simply plug the OSFP end into a switch or adapter that supports 400 Gbit/s, connect the two QSFP56 ends to devices that run at 200 Gbit/s, and the link comes up automatically.

With a 10 meter fiber run, the cable reaches comfortably across adjacent racks or between rows in a data center without the bulk and weight of copper. AOC technology carries the optical engines inside the connectors, delivering the low latency and signal integrity you expect from fiber while keeping installation straightforward. There is no cleaning or polishing of fiber tips and no concern about bending radius beyond what the molded jacket already supports.

The cable is built for InfiniBand HDR environments, making it a practical choice for high performance computing clusters, AI training systems, and storage fabrics that rely on sustained bandwidth and deterministic performance. By breaking out a 400 Gbit/s switch port, you can connect two smaller nodes, balance network topologies, or add bandwidth exactly where it is needed without consuming extra ports on the switch.

Administrators who manage dense GPU servers, scale-out storage, or disaggregated composable infrastructures will appreciate how the splitter cable simplifies cabling plans and reduces points of failure. Engineers who need to upgrade or expand can do so without swapping hardware, because the product follows common OSFP and QSFP56 standards.

Highlights:

• Splits one 400 Gbit/s OSFP port into two 200 Gbit/s QSFP56 links
• 10 meter active optical fiber supports cabinet-to-cabinet and row-to-row runs
• Fully compatible with InfiniBand HDR networking
• AOC design reduces weight and electromagnetic interference versus copper
• Works with switches, adapters, and appliances that expose QSFP56 ports
