BlueOptics QSFP-AOC-3M-FR-BO InfiniBand/fibre optic cable 3m Male/Male

The BlueOptics QSFP-AOC-3M-FR-BO is a 3 metre active optical cable with QSFP male connectors at both ends, designed for InfiniBand and high-speed fibre optic network links. This cable supports short-reach, low-latency connections between switches, servers and network appliances in data centres and high-performance computing environments. The assembly combines optical transceivers and a lightweight, flexible sheath to deliver stable multi-gigabit data transfer over a 3 m distance while reducing electromagnetic interference compared with copper alternatives.

Advantages

This active optical cable offers a compact, plug-and-play solution for high-density racks, providing high bandwidth and low power consumption compared with equivalent copper direct-attach assemblies. The QSFP connectors enable modular, hot-pluggable installation and support multi-lane data transmission for aggregated throughput. The optical construction reduces signal degradation over the 3 m span and eliminates the need for separate transceiver modules, simplifying installation and maintenance.

Suitable for

• Interconnecting switches and server ports in data centres
• High-performance computing clusters using InfiniBand fabrics
• Storage area networks and SAN fabric links
• High-density rack deployments where space and cable management are critical

Key specifications

• Cable type: active optical cable (AOC)
• Connector type: QSFP male to QSFP male
• Length: 3 metres
• Supported protocol: InfiniBand and compatible fibre optic network interfaces
• Transmission: multi-lane high-speed optical data channels
• Applications: short-reach, low-latency interconnects in data centre environments

How to use

Insert the QSFP connectors into compatible QSFP ports on your switches, servers or network adapters, ensuring the connector keying aligns with the port. The cable is plug-and-play and typically recognised automatically by equipment that supports QSFP AOC assemblies. Route the cable through your rack or cable management system, avoiding tight bends and excessive tension to preserve the optical fibres and maintain performance.

Usage recommendations

Handle the cable by the connector housings, avoid kinking or bending the cable beyond the manufacturer’s minimum bend radius, and secure cables to prevent strain on ports. Verify compatibility with device QSFP port types and firmware when integrating into InfiniBand or fibre optic networks to ensure full link performance.
