NVIDIA MFA7U10-H003 OSFP to 2x QSFP56 400 Gb/s Splitter

Preserve fabric density while breaking a single 400 Gb/s HDR link into two 200 Gb/s connections. NVIDIA MFA7U10-H003 is an active optical cable splitter built for InfiniBand environments that need precise port fan-out without adding unnecessary conversion layers or rack clutter. The OSFP-to-2 x QSFP56 design fits high-performance compute and storage networks where every switch port carries real cost. By splitting one twin-port HDR connection into two downstream links, this cable helps align switch uplinks, GPU nodes, and accelerator islands with the bandwidth profile your topology actually needs. At 3 m, it supports short-reach rack and adjacent-rack runs with cleaner cable management than improvised adapter chains. For teams standardizing on HDR infrastructure, this is the kind of interconnect that keeps deployment simple while protecting throughput and layout discipline. Choose it when you need a purpose-built optical splitter for InfiniBand fabrics and want the confidence of a vendor-specific interconnect matched to the platform it serves.
