NVIDIA Mellanox MC2206125-007 QSFP+ to QSFP+ Passive Copper Cable, 7m — Lot of 10: This is a bulk lot of ten 7-meter passive copper Direct Attach Cables (DAC) engineered for InfiniBand QDR (40Gb/s) point-to-point links between QSFP+ ports. This is a passive copper assembly with no active electronics or optics inside the connector ends. This is not an active optical cable (AOC) and does not include signal regeneration. Each unit is refurbished and tested.
Engineering Context
The MC2206125-007 is a fully integrated factory-terminated copper assembly using twin-axial wires. Passive copper consumes essentially no port power on either end (typically less than 0.1W) compared to AOC or transceiver-based links. There is zero serialization latency added by the cable itself. At 7 meters, the cable is at the upper end of typical passive QDR copper reach; some host adapters and switches may require explicit cable-length tuning or FEC adjustments.
Deployment & Use Cases
HPC compute cluster interconnects using ConnectX-2 or ConnectX-3 QDR HCAs. Top-of-rack to mid-row InfiniBand fabric links for storage and compute. Lab and integration environments where a batch of identical cables is needed for fabric build-out. Refresh inventory for legacy QDR fabrics still in active production.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MC2206125-007
Form Factor: QSFP+ to QSFP+ (Point-to-Point)
Cable Type: Passive Copper DAC
Data Rate: 40Gb/s InfiniBand QDR (4x 10Gb/s)
Length: 7m
Quantity: Lot of 10 units
Power per End: Passive (no active electronics)
Protocol: InfiniBand QDR
Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Designed for InfiniBand QDR fabrics on QSFP+ ports of Mellanox ConnectX-2/ConnectX-3 HCAs and SwitchX/IS5000-series QDR switches. Will negotiate down to lower IB rates (DDR, SDR) where supported by both endpoints. 40GbE Ethernet operation is not guaranteed and depends on switch/NIC SerDes support for passive copper at this length — verify before deploying for Ethernet. Not an active cable: do not deploy on platforms that require active signal regeneration. Fixed 7m length, not breakout-capable.
