NVIDIA Mellanox MC2207310-300 QSFP Active Optical Cable, FDR InfiniBand 56Gb/s and 56GbE VPI, 300m: This is a 300-meter active optical cable (AOC) designed for FDR InfiniBand 56Gb/s and 40/56GbE VPI links over QSFP. The AOC integrates VCSEL optics on multi-mode fiber with QSFP connectors permanently terminated at both ends. This is NOT a passive copper DAC and NOT an LR/LR4 single-mode transceiver assembly. Condition: Refurbished.
Engineering Context: The cable carries 56Gb/s aggregate as 4 lanes × 14Gb/s NRZ for FDR InfiniBand, and supports 40GbE / 56GbE Ethernet over the same QSFP interface in VPI mode. The 300m length is a long-reach AOC variant intended for cross-aisle and inter-row data center runs that exceed the practical reach of DAC copper (typically ≤7m) and short-reach AOCs. Power and signaling are delivered through the QSFP electrical interface; no separate optical transceiver pair is required.
Deployment & Use Cases: Used for long inter-rack and inter-row interconnects in HPC clusters running FDR InfiniBand, large MPI fabrics, and storage replication links between distant racks. Common between top-of-rack switches and core/spine FDR switches separated by hundreds of meters, where pulling a single factory-tested AOC is preferable to terminating SMF in the field.
Technical Specifications:
Connector: QSFP to QSFP (factory-terminated)
Cable type: Active Optical Cable (AOC), VCSEL over multi-mode fiber
Data rate: 56Gb/s FDR InfiniBand (4x14G NRZ); 40GbE / 56GbE Ethernet in VPI mode
Length: 300m
Protocol modes: InfiniBand FDR and Ethernet (VPI)
Hot-pluggable: Yes (via QSFP)
Condition: Refurbished
Compatibility & Constraints: Compatible with Mellanox QSFP host ports on ConnectX-3 / ConnectX-3 Pro VPI HCAs and SwitchX / SwitchX-2 switches in FDR or VPI mode. As a long-reach AOC, mid-span splicing or breaking the cable is NOT supported. This cable is NOT a breakout cable and is NOT a 100GbE QSFP28 AOC. Vendor lock-in or DDM compliance on third-party non-Mellanox switches is not guaranteed.
