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

The BlueOptics Q28-AOC-3M-IA-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male is a 3-metre active optical cable designed for high-speed InfiniBand connections. It features QSFP28 connectors on both ends and supports short-reach, low-latency, high-bandwidth links typically required in data centers and high-performance computing clusters. The cable is intended for direct connection between compatible QSFP28 ports and offers a compact, flexible alternative to separate transceivers and fibre patch cords.

Advantages

This 3 m QSFP28 Active Optical Cable provides low latency and high bandwidth suitable for InfiniBand environments. The integrated optical transceivers reduce power and space compared with discrete modules plus patch cords. Its male-to-male QSFP28 configuration simplifies installation and reduces component count. The cable construction offers flexibility for rack and cabinet routing while maintaining signal integrity over the specified distance.

Suitable for

• Short-reach server-to-switch or switch-to-switch connections in data centres
• High-performance computing clusters requiring InfiniBand QSFP28 links
• Storage arrays and compute nodes with QSFP28 ports
• Top-of-rack and aggregation layer interconnects up to 3 metres

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 male on both ends
• Length: 3 metres
• Interface: InfiniBand high-speed link compatible with QSFP28 ports
• Performance: Designed for low-latency, high-bandwidth short-reach connections

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port until the connector latches. Ensure devices are powered down or follow hot-plugging procedures recommended by your hardware vendor if you connect live equipment. Verify link status on both endpoints after installation and check for proper lane mapping and speed negotiation in device interfaces. Avoid sharp bends and excessive strain on the cable during routing to preserve optical performance.

Recommendations

Use this QSFP28 AOC for short-distance links where low latency and high throughput are required. Route the cable with gentle bends, maintain recommended minimum bend radius, and avoid compressive forces near the connectors. Confirm compatibility with your hardware vendor's QSFP28 port specifications and firmware requirements before deployment.
