CBO DAC Cable BlueLAN Dell 470-AAVR QSFP direct-attach cable, 1 m

The CBO DAC Cable BlueLAN Dell 470-AAVR QSFP direct-attach cable, 1 m is a short-range copper interconnect designed for high-speed links between QSFP ports in switches, servers and storage systems. With a 1 metre length and QSFP form-factor, this cable delivers low-latency, point-to-point connectivity suited for rack-level and top-of-rack deployments where a compact, reliable physical link is required.

Advantages

This direct-attach copper cable provides a cost-efficient physical connection with minimal signal conversion and low power consumption compared with active optical alternatives. The QSFP connector and robust construction ensure mechanical compatibility and simple installation in QSFP ports. Its 1 m length reduces cable clutter in confined rack environments while maintaining high throughput and predictable latency for short-distance links.

Suitable for

• Top-of-rack switch-to-switch connections
• Server-to-switch interconnects within the same rack
• Short-distance links in storage arrays and network aggregation
• High-density data centre cabling where low latency and compact routing are required

Key specifications

• Connector type: QSFP (quad small form-factor pluggable)
• Cable type: Direct-attach copper (DAC)
• Length: 1 m
• Intended use: Short-range, high-speed rack-level interconnects
• Design: Passive copper twinax construction for low latency

How to use

Insert each QSFP connector into the corresponding QSFP port on the two devices to be interconnected, ensuring the connector latch engages. No additional transceivers or patch panels are required for direct-attach operation. Verify link status in device management interfaces and confirm supported speeds and link negotiation settings on both endpoints. For reliable operation, route the cable to avoid sharp bends and mechanical strain on the connector ends.

Recommendations

Install the cable in rack-level connections up to 1 metre to maintain optimal signal integrity; avoid excessive bending radii and secure cables to prevent movement. Confirm device compatibility with QSFP passive copper direct connections and check firmware or port configuration if auto-negotiation does not establish the expected link speed.
