BlueOptics Q28-AOC-3M-QL-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male

The BlueOptics Q28-AOC-3M-QL-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male is a 3-metre active optical cable designed for high-speed, low-latency interconnects in data centre and enterprise networking environments. With QSFP28 terminations on both ends, this cable supports direct connections between compatible QSFP28 ports, providing a compact and energy-efficient alternative to separate transceivers and patch cords. The cable is intended for short-reach, high-bandwidth links where signal integrity and minimal latency are required.

Advantages

This 3m QSFP28 AOC delivers reliable high-throughput connectivity while reducing power consumption compared with electrical copper alternatives. The integrated optical transceivers eliminate the need for separate modules, simplifying installation and reducing points of failure. The cable’s QSFP28 Male-to-Male configuration ensures straightforward, tool-free connections between compatible ports, and its active optical design maintains consistent signal quality over the specified distance.

Suitable for

• Short-reach server-to-switch or switch-to-switch links in data centres
• High-performance computing clusters requiring InfiniBand connectivity
• Rack-level interconnects where QSFP28 ports are available
• Low-latency trading platforms and latency-sensitive network segments

Key specifications

• Length: 3 metres
• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Application: InfiniBand / high-speed data centre links
• Performance: Designed for high-bandwidth, low-latency transmission

How to use

Install the BlueOptics QSFP28 AOC by aligning each QSFP28 connector with the corresponding port on the devices to be connected and inserting until the latch engages. No separate transceivers or fibre patch panels are required. Ensure both devices are powered off or follow hot-plug guidelines provided by the equipment manufacturer when connecting live systems. Verify link status indicators on connected equipment to confirm successful negotiation and data link establishment.

Usage recommendations

Place the cable in a layout that avoids sharp bends and excessive strain; maintain the manufacturer’s minimum bend radius. Use appropriate ESD precautions when handling connectors, and keep connector endfaces clean to prevent signal degradation. For predictable performance, use this AOC within the specified 3 m distance and in environments that meet the equipment’s operational temperature and humidity ranges.
