NVIDIA Mellanox MC3309130-00A 10GbE SFP+ Passive Copper Direct Attach Cable, 0.5m — Lot of 10: This listing is for ten (10) units of the MC3309130-00A, a passive copper direct attach cable (DAC) terminated SFP+ to SFP+ for 10 Gigabit Ethernet point-to-point links. Each cable is a fixed-length integrated assembly with permanently terminated connectors; it is not a transceiver pair with separate twinax. All units are Refurbished, tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MC3309130-00A operates passively with no active electronics in the connectors, drawing zero power from the host port and adding no transceiver-induced latency. At 0.5m it is built specifically for adjacent-port and intra-rack connections where the shortest practical reach minimizes cable bulk and improves airflow. The cable carries SFI signaling (10.3125 Gb/s NRZ) end-to-end with very low insertion loss thanks to the short copper run.
Deployment & Use Cases
ToR-to-server connections inside a single rack where the server is in a slot directly adjacent to the switch. Storage controller to host bus adapter linkage in a single chassis. Stacking and inter-switch links between two switches mounted side-by-side. Lab benches and test fixtures requiring a deterministic, transceiver-free 10GbE link.

Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox SX1012 / SN2010 / SX10xx-series SFP+ ports and ConnectX-3 / ConnectX-3 Pro / ConnectX-4 Lx adapters in 10GbE mode. Most third-party SFP+ switch ports that accept passive DACs (such as Arista 7050S, Cisco Nexus, Dell PowerSwitch) link up, but vendor SFP+ DAC compatibility lists should be consulted because some switch OS images filter on cable vendor codes. Not compatible with 25GbE SFP28 ports as a 25G link — the cable is 10G-only. Not compatible with 1GbE SFP-only ports without explicit 10G/1G dual-rate support. Fixed 0.5m length.
