DAC Cable MikroTik DDQ+DA0003 3m QSFP-DD Black

The MikroTik DDQ+DA0003 is a 3-meter direct attach copper (DAC) cable with QSFP-DD connectors on both ends, designed for short-range high-speed connections in data centers and network racks. It provides a 400 Gbit/s electrical interface and a flexible reach that helps link switches, routers and servers across adjacent racks without additional modules.

Advantages

This DAC cable offers a cost-effective and energy-efficient option for 400G connectivity, with integrated QSFP-DD male connectors that plug directly into compatible ports. The fixed 3 m length balances flexibility and neat cabling in rack environments while avoiding the need for optical transceivers for short-distance links.

Suitable for

• Connecting switches within the same rack or adjacent racks
• High-density server-to-switch links in data centers
• Short-reach 400G interconnects where optical modules are unnecessary

Key specifications

• Type: Direct Attach Copper (DAC)
• Length: 3 m
• Connectors: QSFP-DD Male to QSFP-DD Male
• Data rate: 400 Gbit/s
• Color: Black
• Manufacturer: MikroTik, MPN DDQ+DA0003

How to use

Ensure compatible QSFP-DD ports on both devices are available and powered down or follow live-insertion guidelines from your hardware vendor. Align the QSFP-DD connectors and insert the cable firmly into both ports until it seats. Verify link status in your switches or servers and monitor for expected 400G operation. For removal, follow the device-specific procedure to avoid port damage.

Recommendations

Use this DAC for short-distance, high-throughput connections inside racks or between adjacent racks. Avoid bending the cable sharply and keep within manufacturer environmental limits. For longer links, consider compatible optical modules instead of DAC.
