NVIDIA Mellanox MC2207310-005 56Gb/s FDR InfiniBand QSFP Active Optical Cable, 5m: This is a 5-meter active optical cable (AOC) engineered for FDR InfiniBand at 56Gb/s, with integrated QSFP+ form factor on both ends. The cable uses VCSEL 850nm optics over OM3 multi-mode fiber and is factory-terminated for plug-and-play deployment. This is NOT a copper DAC and NOT an EDR (100Gb/s) QSFP28 cable — it is a FDR-class QSFP+ AOC. Condition: Refurbished, tested.
Engineering Context: The MC2207310-005 transports 4x14Gb/s NRZ lanes over MMF using integrated VCSELs at 850nm, with typical per-end power consumption under 1W — well within the QSFP+ thermal envelope. The factory-terminated optical assembly eliminates the fiber end-face contamination risk inherent to discrete transceiver-plus-patch-cord installations and removes one variable from link-budget troubleshooting.
Deployment & Use Cases: Used in FDR InfiniBand HPC clusters, GPU compute fabrics running CUDA-aware MPI, Lustre and GPFS storage interconnects, and spine-leaf links in data centers running mixed FDR InfiniBand and 40GbE workloads on VPI-capable Mellanox switches.
Technical Specifications:
- Primary Protocol: FDR InfiniBand 56Gb/s (4x14Gb/s NRZ)

Compatibility & Constraints: Compatible with NVIDIA Mellanox SwitchX/SwitchX-2 platforms (SX6018, SX6025, SX6036 and IS5030/IS5035 series) and ConnectX-3 / ConnectX-3 Pro VPI adapters. Supports 40GbE on VPI Ethernet ports. NOT compatible with EDR 100Gb/s QSFP28 switch ports (Switch-IB / Spectrum) — those require QSFP28 cabling such as the MFA1A00 series. Not rated for outdoor or industrial high-temperature environments.
