DAC cable CBO 470-ACBX-BL QSFP to QSFP 0.5 m for Dell Mellanox

Direct Attach Copper (DAC) cable CBO 470-ACBX-BL with QSFP to QSFP connectors and a 0.5 m length provides a short-range, wired interconnect for high-speed networking ports. Designed for compatibility with Dell and Mellanox switches and adapters, this copper cable supports low-latency links in dense rack environments where a compact, reliable connection is required. The fixed length and QSFP form factor make it suitable for direct QSFP-to-QSFP connections between adjacent equipment in top-of-rack and rack-to-rack deployments.

Advantages

The DAC cable offers low latency and predictable performance compared to optical transceivers, with no separate transceivers or module power requirements. Its passive copper construction reduces heat and power consumption at the port level and allows straightforward plug-and-play installation. The short 0.5 m length helps to minimize clutter and signal degradation in closely spaced rack setups while ensuring stable, high-bandwidth connectivity for 40/56/100 Gbps-capable QSFP ports when used within supported system specifications.

Suitable for

• Short-range QSFP-to-QSFP links in top-of-rack to aggregation switch connections
• Rack-to-rack connectivity in data centers with adjacent equipment
• Switch-to-server or switch-to-switch links where a compact copper solution is preferred
• Environments requiring low-latency, high-bandwidth direct connections

Key specifications

• Connector type: QSFP to QSFP
• Cable length: 0.5 m
• Media: Direct attach copper (DAC)
• Form factor: QSFP compatible
• Typical use: Short-reach, high-speed interconnects

How to use

Insert each QSFP connector into the corresponding QSFP port on your networking devices, ensuring connectors are fully seated and any port release latches engage. Install and remove the cable with devices powered according to vendor recommendations to avoid hot-plug issues. Confirm that connected devices support DAC cables and the targeted link speeds; monitor the link status via network management interfaces to verify operation. For best results, use the cable within the recommended cable management pathways to avoid excessive bending and mechanical stress.

Recommendations

Use this 0.5 m DAC cable for direct, short-distance QSFP links in rack-dense installations. Avoid sharp bends, excessive tension, and exposure to liquids or extreme temperatures. Confirm compatibility with your Dell or Mellanox hardware and verify supported link speeds in system documentation before deployment.
