BlueOptics QSFP-DAC-5M-CN InfiniBand/glasvezelkabel 4xSFP+ zwart 5m

The BlueOptics QSFP-DAC-5M-CN InfiniBand/fibre optic cable 4xSFP+ Black 5m is a 5-metre direct-attach cable designed to connect high-speed network equipment using a QSFP interface on one end and four SFP+ interfaces on the other. It supports multi-lane data transmission suited to InfiniBand and compatible fibre channel or Ethernet deployments, enabling short-reach, low-latency connections between switches, routers, adapters and servers in dense rack environments.

Advantages

This cable provides consolidated connectivity through a single QSFP to four SFP+ breakout configuration, reducing cabling complexity and saving rack space compared with multiple individual cables. The 5 m length offers flexibility for structured cabling within and between racks while maintaining signal integrity for short-reach links. The black jacket gives a neutral appearance for standardised cable management in data centres.

Suitable for

• High-speed links between QSFP-enabled switches and SFP+ ports on servers or adapters
• InfiniBand fabrics requiring low-latency short-reach connections
• Fibre channel or 10GbE breakout scenarios in rack and cabinet installations
• Environments where consolidated breakout cabling reduces clutter and simplifies maintenance

Key specifications

• Connector configuration: QSFP to 4 × SFP+
• Cable type: direct-attach copper/fibre-compatible breakout assembly for short-reach links
• Length: 5 metres
• Colour: black outer jacket
• Supported protocols: InfiniBand and common 10Gbps SFP+ applications (fibre channel/10GbE)
• Design: low-latency, multi-lane aggregated connection suitable for dense rack topologies

How to use

Insert the QSFP connector into the QSFP port on the upstream switch or adapter and connect the four SFP+ ends to the corresponding SFP+ ports on target devices. Ensure devices are powered down or ports are in a safe insertion state if recommended by the equipment vendor. After physical connection, verify link status through the network equipment management interface and confirm that port speeds and lanes are negotiated correctly. Secure and route the cable to avoid sharp bends and maintain proper airflow in the rack.

Recommendations

Use this cable for short-reach, high-throughput interconnects within racks or between adjacent cabinets. Avoid exceeding the specified bend radius, keep the cable free of heavy pulls or kinks, and follow vendor compatibility lists for QSFP-to-SFP+ breakout support to ensure proper operation.
