Mellanox 2M 10GbE SFP+ to SFP+ Passive Copper DAC Cable — MC3309130-002

The Mellanox MC3309130-002 is a 2-meter 10GbE SFP+ to SFP+ passive copper Direct Attach Cable (DAC). It provides a cost-effective, low-latency 10GbE connection between switches, servers, and storage devices within the same rack or adjacent racks, eliminating the need for separate optical transceivers and fibre cabling.

Key Features

• 2-meter passive copper DAC — no active components or power required
• 10GbE SFP+ to SFP+ — direct rack-to-rack or server-to-switch connectivity
• Lower cost and lower latency than optical transceiver alternatives
• Mellanox OEM — validated for Mellanox and broad third-party compatibility
• Plug-and-play — no driver or configuration required

Frequently Asked Questions

What is the maximum length for a passive DAC cable?

Passive copper DAC cables are typically limited to 5–7 meters. For longer runs, active DAC cables or optical transceivers with fibre are required.

Is this compatible with non-Mellanox switches?

The MC3309130-002 is SFP+ MSA compliant and broadly compatible with most SFP+ equipment. However, some vendors (notably Cisco) may require vendor-specific or approved cables — verify compatibility before deployment.

The Mellanox MC3309130-002 2-meter SFP+ passive copper DAC cable delivers cost-effective, low-latency 10GbE connectivity for rack-level server-to-switch and switch-to-switch connections — a practical alternative to optical transceivers for short-reach 10GbE links.
