NVIDIA Mellanox MC2206130-002 IB QDR 40Gb/s QSFP Passive Copper Cable, 2m: This is a 2-meter passive copper direct-attach cable (DAC) with QSFP connectors on both ends, rated for InfiniBand QDR (40Gb/s, 4×10Gb/s) and 40Gb Ethernet at the physical layer. The cable is a fixed-length factory-terminated assembly with no active electronics. This is NOT an active copper cable, NOT a fiber AOC, and NOT a transceiver. This is a new unit.
Engineering Context
Passive QSFP DACs at 2m incur near-zero forwarding latency compared to active or optical alternatives because they contain no signal-conditioning electronics. The MC2206130-002 is engineered for in-rack and adjacent-rack QDR InfiniBand interconnects where reach is short and per-port power must remain low. Power draw is negligible (under 0.1W) since there are no embedded components, and the cable is fully transparent to host port equalization. Bend radius is rated per the standard QSFP passive copper specification.
Deployment & Use Cases
QDR HPC clusters: server-to-ToR-switch interconnects in compute racks. Lustre and GPFS storage fabrics where short-reach QDR backbones connect storage targets to switches. Legacy ConnectX-2/ConnectX-3 InfiniBand testbeds. 40GbE intra-rack server uplinks where the host NIC and switch both negotiate QSFP+ at 40GbE.

Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox QDR-class switches (IS5000/SX6000-family at QDR rates) and ConnectX-2/ConnectX-3 InfiniBand HCAs. Compatible with switch QSFP+ ports configured for 40GbE on supporting platforms. Not compatible with FDR (56Gb/s), FDR10, EDR (100Gb/s), or HDR speeds — the QSFP signaling on this cable is QDR-rated. Not compatible with QSFP28 100GbE links. Not a breakout cable; this is a 1:1 QSFP-to-QSFP assembly. Fixed 2m length.
