NVIDIA Mellanox MC2210130-001 40GbE QSFP+ Passive Copper Cable, 1m — Lot of 5 (Refurbished): This is a 1-meter passive copper direct-attach cable (DAC) terminated with QSFP+ connectors on both ends for 40Gb/s Ethernet (40GbE) point-to-point links. It is a passive copper assembly with no active components, distinct from active optical cables and from QSFP28 100GbE DACs. This listing is for a multipack of 5 refurbished units.
Engineering Context
40GbE over QSFP+ uses 4 lanes of 10Gb/s NRZ to deliver 40Gb/s aggregate Ethernet bandwidth. The MC2210130-001 is fully passive — zero power, zero added latency from electronics, no firmware to negotiate. At one meter, it sits well within the passive copper reach budget for 40GbE and is ideal for top-of-rack server-to-switch links where every centimeter of cable management matters.
Deployment & Use Cases
Top-of-Rack 40GbE server uplinks to SX1000/SX1700-series Mellanox 40GbE switches. ConnectX-3 EN and ConnectX-3 Pro EN host connections at 40GbE. High-density compute racks where short copper jumpers reduce optics cost. Spare cable inventory for established 40GbE Ethernet fabrics.
Technical Specifications

Form Factor: QSFP+ to QSFP+
Cable Type: Passive Copper (DAC)
Data Rate: 40GbE Ethernet (4× 10Gb/s NRZ)
Length: 1 meter
Protocol: 40GbE Ethernet
Power: 0 W (Passive)
Pack Quantity: 5 cables (Lot of 5)
Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with Mellanox SX1000/SX1700-series 40GbE switches and ConnectX-3 EN / ConnectX-3 Pro EN adapters in 40GbE mode. Both ports must be configured for 40GbE Ethernet — InfiniBand QDR/FDR signaling is not supported by this Ethernet-coded cable. The QSFP+ connector is electrically distinct from QSFP28; do not force into 100GbE QSFP28 ports as a 100G interconnect. Does not support 4× 10GbE breakout to SFP+; for breakout, the QSFP+-to-4×SFP+ family (MC2609xxx) is required.
