NVIDIA Mellanox MC3309124-006 SFP+ 10 Gb/s Passive Copper Direct Attach Cable - MC3309124-006
This passive copper direct attach cable (DAC) is the NVIDIA Mellanox MC3309124-006, an SFP+-to-SFP+ cable rated for 10 Gb/s Ethernet over a 6-meter length. This is a new unit from T.E.S IT-SOLUTIONS. It is NOT an active optical cable (AOC). It is NOT an SFP28 cable — SFP+ connectors operate at 10 Gb/s maximum. The 6-meter length is near the maximum passive copper reach for 10GbE SFP+.
Engineering Context
The MC3309124-006 carries 10 Gb/s over a single lane using NRZ signaling at 10.3125 Gb/s through SFP+ connectors at both ends. At 6 meters, this cable operates near the maximum distance for 10GbE passive copper DAC — signal integrity at this length requires high-quality copper conductors. The passive design requires zero external power and introduces minimal latency. For distances beyond 6-7 meters at 10GbE, active optical cables or fiber patch cables with SFP+ transceivers are required.
Deployment and Use Cases
The MC3309124-006 is deployed for extended-reach 10GbE interconnects within data center racks where shorter DAC cables are insufficient. Common use cases include server-to-ToR switch connections spanning multiple rack units, 10GbE links between ConnectX-3, ConnectX-3 Pro, or ConnectX-4 Lx NICs and SFP+ switch ports, iSCSI and NFS storage network connections requiring 10GbE bandwidth, and lab or staging environments needing 6-meter 10GbE connectivity without optical transceivers.
Technical Specifications
Model: MC3309124-006
Type: Passive Copper DAC (Direct Attach Cable)
Connectors: SFP+ to SFP+
Data Rate: 10 Gb/s (10GbE)
Signaling: NRZ (single lane)
Length: 6 m
Power: Passive (zero power consumption)
Condition: New
Compatibility and Hard Constraints
The MC3309124-006 connects any two devices with SFP+ ports operating at 10 Gb/s. Compatible with ConnectX-3, ConnectX-3 Pro, ConnectX-4 Lx NICs and any Ethernet switch with SFP+ cages. It is NOT compatible with SFP28 ports operating at 25 Gb/s — SFP+ and SFP28 are mechanically compatible but this cable is rated for 10 Gb/s only. Not suitable for QSFP, QSFP28, or QSFP56 ports. The 6m length is near the maximum passive copper reach for 10GbE SFP+ — for longer distances, use active optical cables or SFP+ transceivers with fiber.
