Cabo DAC CBO BN-QS-SP-CBL-1M 1 m de comprimento compatível com BlueLAN QSFP

The CBO DAC cable BN-QS-SP-CBL-1M 1 m length compatible with BlueLAN QSFP is a 1 metre passive Direct Attach Copper (DAC) cable engineered for short-reach, high-bandwidth connections between QSFP-enabled network devices. It provides a direct copper link suitable for top-of-rack and switch-to-switch interconnects in data centres, offering lower latency and reduced power consumption compared with equivalent active optical assemblies. The cable is compatible with BlueLAN QSFP ports and is intended for use where a compact, reliable, and cost-effective wired connection is required.

Advantages

This 1 m passive DAC cable delivers high-speed throughput with minimal signal conversion, which reduces latency and energy use. Its passive design eliminates the need for external power, simplifying installations and lowering operational cost. The fixed one-metre length provides predictable signal integrity for short links and reduces clutter in rack environments. Compatibility with QSFP ports ensures straightforward integration with QSFP-enabled switches, servers and transceivers.

Key specifications

How to use

Insert each QSFP-compatible connector into the corresponding QSFP port on the two devices to be linked, ensuring secure seating until the connector latch engages. Verify that both devices recognize the link and that interface diagnostics report expected speed and status. For optimal performance, use this cable only for short-range links as intended; avoid excessive bending or strain on the cable and maintain clear airflow in rack environments.

Recommendations

For reliable long-term operation, route the cable to avoid sharp bends and mechanical stress, maintain proper rack cable management to prevent airflow obstruction, and verify compatibility with QSFP ports on both devices before installation. Use the one-metre length for intra-rack and adjacent-rack connections where short latency and low power consumption are priorities.
