NVIDIA Mellanox MC3309130-001 SFP+ 10GbE Passive Direct Attach Copper Cable, 1m (Lot of 10): This is a 1-meter passive direct attach copper (DAC) cable with SFP+ connectors on both ends, engineered for 10 Gigabit Ethernet (10GbE) point-to-point links. This is a fixed-length integrated assembly, not a transceiver pair with a separate patch cord. Sold as a lot of 10 refurbished units.
Engineering Context
The MC3309130-001 uses twinaxial copper conductors with EMI-shielded SFP+ paddle cards. As a passive cable, it requires no external power and adds negligible latency compared to active equalized variants. The 1-meter length is targeted at intra-rack connections such as adjacent server-to-Top-of-Rack (ToR) switch links. Power consumption per end is effectively zero. The cable carries Mellanox firmware identification used by switches for compatibility validation.
Deployment & Use Cases
10GbE intra-rack server-to-ToR switch uplinks. Storage controller-to-server connections within a single rack. SFP+ port aggregation on adjacent 1U/2U appliances. Lab and test bench setups requiring short, low-cost 10GbE links.
