NVIDIA Mellanox MC3309130-003 10GbE SFP+ Passive Copper DAC, 3m — Lot of 10: This listing is a bulk lot of ten (10) 3-meter passive copper SFP+ direct-attach cables (DAC) for 10GbE Ethernet point-to-point links. Each cable is a fixed-length integrated assembly with SFP+ connectors on both ends, no active electronics. This is not an optical cable, transceiver, or breakout assembly. All units are refurbished and tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MC3309130-003 is a passive twinaxial copper DAC built for short-reach intra-rack 10GbE connectivity. At 3 meters it sits in the sweet spot for Top-of-Rack to compute-node links where passive copper has the lowest latency, lowest power, and lowest cost compared to AOC or transceivers with patch cords. Passive DAC dissipates no port power for SerDes-driving electronics. Lot pricing reduces per-unit cost for full-rack rollouts and bulk spare-pool builds.
Deployment & Use Cases
Within-rack 10GbE between SFP+ Top-of-Rack switches and ConnectX adapters in compute nodes. Bulk rollout of full racks of 10GbE Ethernet attachment. iSCSI and NFS storage links to 10GbE-attached storage arrays. Spare-pool replenishment for existing 10GbE deployments using MC3309130-003.

Compatibility & Constraints
Compatible with NVIDIA Mellanox SX1012/SX1024/SX1410 and similar SFP+ 10GbE switches, ConnectX-3/-4 EN SFP+ adapters, and most third-party SFP+ 10GbE ports that accept Mellanox-coded passive DACs. Vendor port-coding lockouts may reject Mellanox-coded DACs on some Cisco/Arista platforms; verify port-coding policy before deployment. Not a 25GbE SFP28 cable; will not negotiate above 10Gb/s. Passive DAC does not support 1GbE auto-negotiation on all SFP+ ports. Fixed 3m length, no breakout. Lot-of-10 ships as ten discrete cables.
