NVIDIA Mellanox MC2210128-003 QSFP+ 40GbE Passive Copper Cable, 3m: This is a 3-meter passive copper direct-attach cable (DAC) with QSFP+ connectors on both ends, rated for 40GbE Ethernet. This is a fixed-length passive copper assembly, not an active optical cable and not a breakout cable. This is a refurbished unit.
Engineering Context
The MC2210128-003 is a 40GBASE-CR4 passive copper cable for short-reach 40G Ethernet. It uses 4 lanes of 10Gb/s NRZ over twinaxial copper with full shielding for EMI immunity. Passive DACs consume 0 W and add no retiming latency. The 3m length is well within the standard 7m passive copper reach budget for 40GbE. Connectors are factory-terminated and tested.
Deployment & Use Cases
40GbE Top-of-Rack uplinks between adjacent switches. Server NIC to ToR switch at 40GbE in compact rack layouts. Aggregation between SX1000-series Ethernet switches. Storage interconnect at 40G where fiber AOC is unnecessary.
