NVIDIA Mellanox MC2207312-100 56Gb/s FDR QSFP+ Active Optical Cable, 100m, VPI: This is a 100-meter active optical cable (AOC) supporting Mellanox VPI — InfiniBand FDR at 56Gb/s and 56GbE Ethernet — over a single QSFP+ to QSFP+ assembly. Active optics inside each QSFP+ housing convert electrical signals to light over multi-mode fiber. This is a fixed-length factory-terminated assembly, not a transceiver with a detachable patch cord. This is a refurbished unit.
Engineering Context
The MC2207312-100 enables 100m reach for FDR-class fabric, well beyond the limits of passive copper DAC at 56Gb/s (typically capped at 5m). VPI capability means the same physical cable can operate as InfiniBand FDR or 56GbE Ethernet, depending on host port configuration. The QSFP+ form factor uses 4 lanes of 14Gb/s NRZ signalling for FDR. Active optics over multi-mode fiber provide EMI immunity and low cable weight versus copper alternatives over long runs.
Deployment & Use Cases
Long-reach FDR InfiniBand fabric links between rows in HPC clusters. 56GbE Ethernet uplinks across data hall distances. Mixed-protocol VPI deployments where the same cable inventory must serve both InfiniBand and Ethernet roles. Connections from compute aggregations to centralized core switches where copper bundles are impractical due to weight or distance.

Compatibility & Hard Constraints
Compatible with Mellanox SX6000 series FDR InfiniBand switches and ConnectX-3, ConnectX-3 Pro VPI adapters running FDR or 56GbE. Compatible with VPI-capable switches that support both InfiniBand and Ethernet on QSFP+ ports. Not rated for EDR (100Gb/s) or HDR (200Gb/s); the cable is FDR-class only. Not compatible with QSFP28 ports unless the platform negotiates down to FDR rates. Fixed 100m length; cannot be extended.
