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

The BlueOptics Q28-AOC-3M-IB-BO InfiniBand fibre optic cable 3m QSFP28 Male is a 3-metre active optical cable designed for high-speed, short-range interconnects in data center and high-performance computing environments. Both ends terminate in QSFP28 male connectors, offering a compact direct-attach solution for linking switches, servers and storage equipment. The cable supports InfiniBand signaling and is intended to deliver the high bandwidth and low latency required by cluster computing, storage fabrics and aggregation topologies.

Advantages

This 3 m QSFP28 AOC provides electrical isolation and immunity to electromagnetic interference while maintaining the throughput characteristics of optical transmission. Its integrated optical transceivers simplify deployment by eliminating separate transceiver modules, reducing component count and physical footprint. The cable’s QSFP28 form factor supports multi-lane high-speed links and is compatible with equipment that accepts QSFP28 direct-attach optical connections. The solution is lightweight and flexible for clean cable management in dense rack environments.

Suitable for

• High-performance computing clusters requiring low-latency interconnects
• Data centre switch-to-server or switch-to-switch links within the same rack or adjacent racks
• Storage area network connections and NVMe-over-Fabrics links
• Top-of-rack aggregation and spine-leaf architectures with InfiniBand support

Key specifications

• Cable type: Active optical cable (AOC)
• Length: 3 metres
• Connector type: QSFP28 male to QSFP28 male
• Supported protocol: InfiniBand (high-speed serial lanes)
• Typical use: Short-range high-bandwidth interconnects in data centre environments
• Physical properties: Lightweight, flexible optical assembly suitable for dense cabling

How to use

Install the cable by aligning each QSFP28 male connector with the corresponding QSFP28 port on your switch, server or storage device and insert until the latch engages. Ensure equipment is powered down or follows manufacturer hot-plug guidance if applicable. Verify link status through your device management interface or LEDs after connection. Route the cable to avoid sharp bends and maintain the recommended bend radius to preserve optical performance. If replacing an existing link, confirm compatible port types and supported protocols before swapping.

Usage recommendations

For reliable operation, use this BlueOptics QSFP28 AOC within rack or adjacent-rack distances specified for short-range optical interconnects. Avoid tight bends, excessive torsion and prolonged exposure to mechanical stress. Confirm firmware and port compatibility on networking equipment to ensure full lane utilization and expected data rates.
