BlueOptics AA1404036-E6 InfiniBand fibre optic cable 5 m QSFP 4xSFP+ Black

The BlueOptics AA1404036-E6 InfiniBand fibre optic cable 5 m QSFP 4xSFP+ Black is a 5-metre multimode link assembled with a QSFP connector on one end and four SFP+ connectors on the other. It is intended for short-reach, high-bandwidth interconnects in rack, top-of-rack and switch-to-switch environments that require low latency and high throughput. The cable's factory-terminated male connectors simplify installation and help maintain consistent signal integrity across multiple parallel lanes.

Advantages

This InfiniBand fibre optic cable supports parallel high-speed transmission through a single QSFP-to-4×SFP+ breakout, reducing the number of separate fibres and ports required for equivalent throughput. The 5 m length offers flexibility for deployment inside racks and between adjacent network devices while avoiding excess slack. Factory-terminated connectors provide repeatable performance and reduce the need for onsite termination, and the cable construction is designed to preserve low insertion loss and minimize crosstalk between channels.

Suitable for

• High-speed server-to-switch and switch-to-switch connections in data centres
• InfiniBand clusters and high-performance computing interconnects
• Top-of-rack and patch-panel breakout configurations
• Short-reach links requiring QSFP to multiple SFP+ interfaces

Key specifications

• Connector configuration: QSFP on one end, four SFP+ on the other
• Length: 5 metres
• Transmission type: fibre optic, designed for InfiniBand and high-speed data links
• Cable colour: black
• Application: short-reach, parallel lane breakout cabling for high-throughput interconnects

How to use

Install the cable by inserting the QSFP male connector into the QSFP port on the source device and plug the four SFP+ male connectors into the corresponding SFP+ ports on the destination device(s). Ensure connectors are fully seated and that port dust caps have been removed prior to insertion. Route the cable to avoid tight bends and mechanical strain; maintain the manufacturer's recommended bend radius to preserve optical performance. Verify link status on connected devices and perform any necessary link diagnostics or port configuration to enable the aggregated or individual lanes.

Recommendations

For reliable operation, keep fibre endfaces clean and protect unused ports with dust caps. Use the 5 m length for deployments within or between adjacent racks; for longer runs select appropriate longer multimode or singlemode fibre solutions. Confirm compatibility of connected devices with QSFP-to-4×SFP+ breakout configurations and follow equipment vendor guidance for lane mapping and speed negotiation.
