DAC cable CBO AA1404030-E6 30m QSFP direct-attach copper cable

Direct-attach copper (DAC) cable CBO AA1404030-E6 30m QSFP direct-attach copper cable is a 30-meter passive QSFP-compatible copper assembly designed for short-range, high-speed interconnects in data center environments. The cable provides a direct QSFP-to-QSFP connection between network devices, such as switches and servers, eliminating the need for separate optical transceivers and offering a compact, low-latency physical link for rack-to-rack or within-rack deployments.

Advantages

The DAC cable delivers predictable latency and stable electrical performance suited to short-distance/high-bandwidth applications. As a passive QSFP direct-attach copper solution, it reduces component count and power consumption compared with transceiver-plus-fiber alternatives. Its 30 m length supports flexible placement of equipment across adjacent racks or larger enclosures while maintaining signal integrity for multimode QSFP interfaces. The cable is compatible with standard QSFP ports and is suitable for environments that require a fixed, durable copper link.

Suitable for

• Rack-to-rack high-speed connections in data centers
• Within-rack interconnects between switches, routers and servers
• Low-latency links for storage and compute clusters
• Environments where passive copper assemblies are preferred over optical transceivers

Key specifications

• Connector type: QSFP direct-attach copper interface
• Cable type: Passive copper twinax assembly
• Length: 30 meters
• Application: Short-range high-speed interconnects (data center)
• Latency: Low electrical latency suitable for high-performance networking
• Compatibility: Standard QSFP ports on switches, servers and network devices

How to use

Insert the QSFP connectors into the QSFP ports of the two devices to be linked, ensuring proper orientation and secure seating. No additional transceivers or fiber patching are required; the cable establishes a direct electrical link between QSFP interfaces. Verify link status and speed via device management interfaces after connection. When installing, route the cable to avoid tight bends and mechanical strain, and secure it to rack fixtures if needed to prevent tension on the connectors.

Recommendations

Use this 30 m passive QSFP DAC for short-range connections where a fixed copper solution is acceptable. Confirm QSFP port compatibility and supported link speeds on your equipment before deployment, and keep bend radius and environmental limits in mind to preserve signal integrity and connector lifespan.
