NVIDIA Mellanox MC2207310-033 56Gb/s VPI Active Optical Cable, QSFP+, 33m: This is a 33-meter active optical cable (AOC) engineered for FDR InfiniBand at 56Gb/s and 56GbE Ethernet over the same QSFP+ form factor. The cable is built for VPI (Virtual Protocol Interconnect) deployments where the same physical link can carry InfiniBand or Ethernet depending on switch configuration. This is a fixed-length integrated assembly with embedded VCSEL optics on multi-mode fiber, not a transceiver with a detachable patch cord. This is a refurbished unit.
Engineering Context
The MC2207310-033 covers spans far beyond the reach of QSFP+ passive copper, which tops out at roughly 7m. At 33 meters the AOC bridges aggregation rows and remote racks while keeping link weight and bend radius manageable. Multi-mode VCSEL optics deliver line-rate 56Gb/s suited to the BER and latency demands of InfiniBand RDMA traffic. The cable is fully shielded and EMI-immune, allowing routing past power tray runs without crosstalk concerns.
Deployment & Use Cases
InfiniBand FDR fabric links between Mellanox SX6000-series spine switches and aggregation chassis. 56GbE Ethernet uplinks for ConnectX-3 Pro VPI HCA-equipped servers. HPC clusters where east-west fabric runs exceed copper reach. Storage fabrics tying SX6036/SX6018 to remote JBOD shelves. Cross-row VPI deployments requiring a 33m span that passive copper cannot serve.
Technical Specifications

Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with Mellanox SwitchX and SwitchX-2 family (SX6000, SX6036, SX6018, SX6710) and ConnectX-3, ConnectX-3 Pro, and ConnectX-4 VPI adapters configured for FDR. Operates in InfiniBand FDR or 56GbE Ethernet modes; switch ports must be configured accordingly. Not compatible with QSFP28 100GbE or EDR ports — this is a QSFP+ generation cable. Not compatible with 40GbE-only platforms that do not negotiate 56GbE FDR signalling. Fixed 33m length; no breakout support.
