Network Cable BlueOptics Mellanox 00KF006 QSFP DAC SC252501K3M30 3m Blue

The BlueOptics Mellanox compatible BlueLAN QSFP DAC cable (3 m, blue) provides a direct-attach copper connection for short-reach, high-bandwidth links in data center and enterprise networks. Designed for use with QSFP ports, this 3-meter passive DAC delivers low-latency, energy-efficient transmission between switches, servers and storage systems. Its rugged jacket and secure connector housing support reliable physical handling and straightforward identification by color.

Advantages

This QSFP DAC cable offers a compact, low-power alternative to optical transceivers for short-distance links, enabling high throughput with minimal protocol overhead. The fixed 3 m length reduces clutter and improves airflow in rack deployments, while the metal-reinforced QSFP connector ensures a stable electrical interface. The blue jacket aids cable management and rapid visual identification during installation or maintenance.

Suitable for

• Interconnects between QSFP-enabled switches within the same rack or adjacent racks
• Direct server-to-switch connections requiring high bandwidth and low latency
• Storage array links and short-distance aggregation in data center topologies

Key specifications

• Connector type: QSFP (Quad Small Form-factor Pluggable) direct-attach copper
• Length: 3 meters
• Cable construction: shielded twinax copper with protective jacket
• Color: blue for easy identification
• Performance: suitable for high-throughput, low-latency short-reach links
• Power profile: passive (low power consumption) for short distances

How to use

Install the cable by aligning each QSFP plug with the respective port on network switches, servers or storage devices and insert until the connector latch engages. Ensure devices are powered and configured to recognize DAC modules; in some systems a compatible host firmware or driver may be required for full feature support. Route the cable to avoid sharp bends and secure it to rack management points to maintain proper airflow and prevent mechanical strain.

Usage recommendations

For optimal reliability, use this 3 m QSFP DAC for intra-rack or adjacent-rack connections where distances stay within the cable’s passive reach. Verify port compatibility with QSFP interfaces on your networking equipment and avoid exposing the cable to excessive heat or mechanical stress. Regular visual inspections and proper cable management will prolong service life and maintain consistent performance.
