Description

NVIDIA Mellanox MFA7U10-H010 InfiniBand 400G OSFP to 2x 200G QSFP56 Active Optical Splitter, 10m: This is a 10-meter active optical splitter cable that converts a single 400Gb/s twin-port OSFP InfiniBand interface into two 200Gb/s QSFP56 endpoints. The integrated optics re-time and electrically isolate each lane group. This is a fixed-length integrated assembly, not a transceiver with a detachable patch cord. This is a refurbished unit.

Engineering Context

The MFA7U10-H010 carries 8x 50Gb/s PAM4 lanes on the OSFP side, mapped as two 4-lane HDR groups (2x 200Gb/s) on the QSFP56 side. At 10 meters it bridges cross-rack and short cross-row spans where copper splitters cannot maintain signal integrity at 400G aggregate. The OSFP form factor includes an integrated finned heat sink for active power dissipation; ensure the host switch maintains MSA-compliant airflow. Active optics provide complete EMI immunity, low weight, and tighter bend radius (30mm minimum recommended) than equivalent copper, easing routing through dense cable trays.

Deployment & Use Cases

Connecting NVIDIA Quantum-2 (NDR) switch OSFP ports configured in 2x HDR split mode to ConnectX-6 / ConnectX-6 Dx VPI HCAs across racks. Doubling effective port count of OSFP-based InfiniBand spine or leaf switches feeding HDR compute nodes. AI/ML training fabrics that bridge a Quantum-2 backbone to existing HDR Quantum (QM87xx) edge over 10m cross-rack runs. Storage Area Networks running NVMe-oF over RDMA between mixed-generation aisles.

Compatibility & Hard Constraints

Compatible with NVIDIA Quantum-2 (NDR) switches with OSFP ports configured for 2x200G HDR split mode, NVIDIA Quantum HDR (QM87xx series) on the QSFP56 side, and ConnectX-6 / ConnectX-6 Dx VPI HCAs. Requires switch firmware that supports HDR split-mode signaling. Not compatible with QSFP-DD ports (OSFP is mechanically incompatible). Not validated for Ethernet-only platforms. Fixed 10m length — not field-shortenable.
