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

The BlueOptics Q28-AOC-3M-IX-BO InfiniBand fibre optic cable is a 3-meter active optical cable with QSFP28 male connectors on both ends, engineered for high-speed data transmission in dense networking environments. Its design targets low-latency links between switches, servers and storage arrays, supporting the high throughput demands of modern data centers and high-performance computing clusters.

Advantages

This InfiniBand fibre optic cable provides a compact and energy-efficient alternative to copper for short-reach, high-bandwidth links. Active optics reduce signal loss over the 3 m length, maintaining signal integrity and consistent throughput. QSFP28 connectors deliver a standardized interface for 100Gb/s-class ports, while the male-to-male configuration simplifies direct connections between compatible equipment without additional transceivers.

Suitable for

• Interconnects between data centre switches and aggregation devices
• High-performance computing (HPC) cluster node connections
• Server-to-storage links in SAN and NAS environments
• Short-reach, high-bandwidth links in blade chassis and rack deployments

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 3 meters
• Interface class: InfiniBand compatible, suitable for 100Gb/s QSFP28 ports
• Typical use: Short-reach, rack-to-rack and intra-rack high-bandwidth links
• Signal characteristics: Low latency, reduced insertion loss compared to passive solutions

How to use

Install the BlueOptics QSFP28 AOC by aligning each QSFP28 male connector with the corresponding port on your switch, server or storage device and gently inserting until the connector latches. No additional transceivers or fibre termination are required. Ensure devices are powered down or follow hot-plugging recommendations from equipment vendors when connecting or disconnecting to avoid port damage. Verify link status via device management interfaces after connection.

Recommendations

Route the cable to avoid sharp bends and maintain the recommended minimum bend radius for QSFP28 AOCs. Keep the cable away from sources of electromagnetic interference and mechanical stress. For optimal performance, match the cable to ports that support 100Gb/s QSFP28 or InfiniBand-compatible interfaces and confirm firmware or driver compatibility on connected devices.
