Network Cable BlueOptics Mellanox 00KF004 QSFP DAC SC252501K1M30 1m Blue

The BlueOptics Mellanox 00KF004 QSFP DAC SC252501K1M30 1m Blue is a direct attach copper (DAC) network cable designed for short-distance, high-speed interconnections. Compatible with Mellanox QSFP ports, this BlueLAN cable supports data transmission up to 100 Gbps and is supplied in a 1 meter length. It is intended for use in data centers and high-performance networking setups where low-latency, reliable links between devices are required.

Advantages

This QSFP DAC cable provides native 100 Gbps bandwidth over a short 1 m span, reducing the need for optical transceivers and associated power consumption. Its direct attach design simplifies installation between compatible QSFP ports and helps maintain low latency and signal integrity. The cable’s blue jacket aids in visual identification within structured cabling environments.

Suitable for

• Server-to-switch connections in data centers
• Switch-to-switch uplinks within racks or adjacent racks
• High-performance computing clusters requiring low-latency links
• Environments where 1 m passive copper interconnects are appropriate

Key specifications

• Connector type: QSFP (Quad Small Form-factor Pluggable)
• Supported data rate: up to 100 Gbps
• Cable type: Direct Attach Copper (DAC)
• Length: 1 metre
• Color: blue

How to use

Ensure both devices have compatible QSFP ports and that firmware or driver compatibility with Mellanox-compatible DAC cables is met. With devices powered down or following hot-plug guidance from your hardware vendor, align and insert the QSFP connectors into the ports until they seat securely. Verify link status and configuration in your switch or server management interface. For removal, follow vendor guidance to avoid abrupt disconnection during critical traffic.

Usage recommendations

Use this 1 m BlueOptics Mellanox QSFP DAC cable for short, high-speed interconnects inside racks or between adjacent racks. Keep bend radii within manufacturer-recommended limits, avoid excessive pulling or kinking, and maintain clear labeling in cable management systems to ensure predictable maintenance and troubleshooting.
