    Overview

    NVIDIA Mellanox MFA7U10-H005 Overview

    The Mellanox MFA7U10-H005 is a high-performance active optical splitter cable designed for InfiniBand HDR data center and high-performance computing environments. This 1x OSFP to 2x QSFP56 AOC connects a single 400Gb/s HDR port to two 200Gb/s HDR ports, making it ideal for dense GPU clusters, storage fabrics, and latency-sensitive workloads across Asia, Europe, Africa, and North America. With an aggregate data rate of 400Gb/s over active optical fiber, the MFA7U10-H005 delivers stable bandwidth and low bit-error performance over a fixed 5 m reach, helping integrators and resellers simplify high-speed deployments.

    For distributors, the MFA7U10-H005 offers a consistent, vendor-aligned option for NVIDIA/Mellanox InfiniBand HDR 400G OSFP switch ports and HDR 200G QSFP56 adapter ports, reducing compatibility issues and RMA risk. Small and mid-size system integrators benefit from a plug-and-play design that removes the need to manage separate transceivers and fiber patch cords, shortening installation time and easing on-site support. End users running HPC, AI training, or large-scale research computing gain predictable, high-throughput links between compute nodes and leaf or spine switches, with a simple 1:2 split ratio that helps scale capacity without redesigning the fabric.

    The OSFP host side connector presents a dual-port 400Gb/s interface that is purpose-built for modern HDR switches and director-class systems, while the two QSFP56 200Gb/s ends connect directly to compatible HDR adapters or edge ports. Because it uses active optical fiber as the transmission medium, the cable is light, flexible, and easier to route in high-density racks than copper assemblies, especially in hot aisles and overhead trays. The 5 m length is well suited to typical rack-to-rack or rack-to-row deployments in standard data halls, offering enough slack for clean cable management without excess coil and loss.

    Across regions, from hyperscale and cloud providers to enterprise and research labs, the Mellanox MFA7U10-H005 helps standardize InfiniBand HDR connectivity with a fully integrated, factory-terminated solution. It minimizes optical handling in the field, supports consistent HDR 400Gb/s to 2x200Gb/s connectivity, and aligns with same-vendor NVIDIA/Mellanox environments where long-term support and firmware compatibility are key purchasing criteria. This makes the MFA7U10-H005 a practical choice for channel partners building repeatable high-speed solutions and for end customers who want reliable performance with straightforward deployment.
