NVIDIA Mellanox MC2207312-003 InfiniBand FDR 56Gb/s VPI QSFP+ Active Optical Cable, 3m (Lot of 4): This is a 3-meter active optical cable (AOC) with QSFP+ connectors on both ends, engineered for InfiniBand FDR (56Gb/s) and 56GbE Ethernet point-to-point links over multi-mode fiber (VPI dual-protocol). The cable is a fixed-length integrated assembly; the optics are integrated into the QSFP+ paddle cards and not user-replaceable. Sold as a lot of 4 refurbished units.
Engineering Context
The MC2207312-003 uses VCSEL optics over multi-mode fiber, terminated as a QSFP+ AOC. The cable carries 4 lanes at 14.0625 Gb/s NRZ, aggregated to FDR 56 Gb/s. As a VPI (Virtual Protocol Interconnect) cable, the same physical link can be used for InfiniBand FDR or 56GbE Ethernet depending on host configuration. The fiber assembly is lighter and more flexible than copper at the same data rate, and provides full EMI immunity for runs near power distribution.
Deployment & Use Cases
FDR InfiniBand interconnects in HPC and MPI workloads. 56GbE Ethernet uplinks for storage spine designs. Mid-row cabling between racks where 3m copper is impractical. GPU compute nodes connecting to FDR-capable Mellanox SX6000-series switches.

Compatibility & Hard Constraints
Compatible with Mellanox SX6000-series FDR InfiniBand switches and ConnectX-3/3 Pro VPI adapters configured for FDR or 56GbE. Requires the QSFP+ host port to support the selected protocol (InfiniBand or Ethernet) on each end. Not compatible with EDR (25 Gb/s lane) or HDR (50 Gb/s lane) ports without rate negotiation. Not compatible with QSFP28 100G hosts. Fixed 3m length; integrated optics are not field-replaceable.
