DAC cable CBO BN-QS-QS-CBL-2M-IB-BL 2 m QSFP direct attach blue

The DAC cable CBO BN-QS-QS-CBL-2M-IB-BL 2 m QSFP direct attach blue is a 2-metre Direct Attach Copper (DAC) cable with QSFP connectors, designed for short-distance, high-speed interconnects. With a fixed copper link and QSFP interface, the cable provides a low-latency physical connection between QSFP-enabled switches, network interface cards (NICs) and storage systems. The blue outer jacket simplifies port identification and cable management in dense rack environments, while the pre-terminated assembly eliminates the need for separate transceivers or field termination.

Advantages

This QSFP direct attach cable offers reduced latency and consistent electrical performance for short-reach links, avoiding the overhead and power consumption of separate optical transceivers. The integrated QSFP connectors ensure plug-and-play installation and reliable mating with QSFP ports. The 2-metre length supports common rack and top-of-rack cabling runs without excess slack, and the coloured jacket improves visual organisation of network cabling.

Suitable for

• Inter-switch connections in data centre racks
• Direct links between QSFP-capable NICs and switches
• High-speed connections for storage arrays and server uplinks
• Top-of-rack and short in-rack cabling runs

Key specifications

• Type: Direct Attach Copper (DAC) cable with QSFP connectors
• Length: 2 metres
• Connector interface: QSFP (plug-in fixed assembly)
• Cable jacket colour: blue for port identification
• Use case: short-range, high-speed electrical interconnect
• Latency: low (fixed copper link)

How to use

Insert each QSFP connector into corresponding QSFP ports on the devices to be linked, ensuring correct orientation and full seating until the connector latch engages. Verify link status on connected devices and manage cable routing to avoid sharp bends or mechanical strain. The pre-terminated assembly requires no additional transceivers; handle the cable by the connector housings during installation and avoid excessive twisting or kinking of the cable run.

Recommendations

For optimal performance, use this 2 m QSFP DAC cable for short, direct links within racks or between adjacent racks. Maintain bend radii recommended by the manufacturer, avoid tight cable bundles that could increase heat, and confirm compatibility with device QSFP ports and supported data rates before deployment.
