NVIDIA Mellanox MC2206230-010 QSFP Passive Copper Cable, IB QDR 40Gb/s, 10m: This is a 10-meter QSFP-to-QSFP passive copper twinax cable engineered for 4X QDR InfiniBand (40Gb/s aggregate) point-to-point links. It is a fixed-length, terminated copper assembly — it is not an active optical cable, not a transceiver-and-patch-cord pair, and not an FDR or EDR cable. This unit is supplied refurbished in tested working condition.
Engineering Context. The cable carries 4 lanes at 10Gb/s NRZ each (4x10G) for a 40Gb/s line rate over a copper twinax pair construction with QSFP (SFF-8436) housings on both ends. As a passive cable, it draws 0 W and contains no signal-active electronics; the link relies entirely on the host and switch SerDes for equalization and clock recovery. The 10m length sits at the upper end of QDR passive copper reach, making it suitable for in-rack and short adjacent-row runs rather than long-distance interconnects.
Deployment & Use Cases. Typical use cases include QDR HPC compute clusters, GPU and storage pods served by QDR-capable IS5000-series and SX6036 switches, parallel filesystem backends running Lustre or GPFS over InfiniBand, and lab and benchmarking environments where reliable copper QDR is preferred over the cost and handling complexity of optics.

Compatibility & Constraints. Works with QDR-capable Mellanox HCAs (ConnectX-2, ConnectX-3) and QDR-capable InfiniBand switches that accept passive copper QSFP cables (IS5000-series, SX6036 in QDR mode). It is not a drop-in replacement for FDR (56Gb/s) or EDR (100Gb/s) media — those rates require their own purpose-built cables. At 10m, the cable runs near the upper boundary of QDR passive copper reach; verify that host and switch firmware recognize the cable EEPROM for clean linkup.
