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

The BlueOptics QSFP-AOC-3M-LC-BO InfiniBand fibre optic cable is a 3-meter active optical cable designed for high-density networking environments. With QSFP form-factor connectors and male-to-male termination, this cable provides a direct optical link between compatible QSFP ports to support high-speed data transfers in data centres, server racks and switch interconnects. The cable construction minimises electromagnetic interference and supports stable, low-latency communication over a 3 m distance.

Advantages

This active optical cable offers the bandwidth and signal integrity required for InfiniBand links while reducing power consumption compared with some copper alternatives. Its QSFP male-to-male connectors enable plug-and-play installation with compatible transceiver ports, and the 3 m length provides a balance between reach and cable management in dense rack layouts. The fibre medium ensures immunity to electrical noise and maintains consistent performance in environments with multiple high-speed links.

Suitable for

• Interconnecting QSFP ports on switches, routers and host adapters
• Server-to-switch links in data centre racks
• High-performance computing (HPC) and InfiniBand fabrics
• Low-latency storage area network (SAN) connections

Key specifications

• Connector type: QSFP male to QSFP male
• Cable type: Active Optical Cable (AOC)
• Length: 3 metres
• Application: InfiniBand high-speed data interconnects
• Medium: Fibre optic
• Latency: designed for low-latency links
• Shielding: immune to electromagnetic interference due to optical transmission

How to use

Ensure both devices have compatible QSFP ports that support InfiniBand over active optical cables. Align the connector keyed guides and insert the QSFP plugs straight into the ports until they click into place. Verify link status on the connected devices and configure network settings according to your InfiniBand fabric or switch requirements. To disconnect, press the release mechanism (if present) and withdraw the connector carefully to avoid stressing the fibre.

Recommendations

Route the cable with gentle bends and avoid sharp kinks; maintain the manufacturer’s minimum bend radius. Keep connectors covered when not in use to prevent contamination. Use cable management accessories in racks to prevent strain on ports and to preserve signal integrity for sustained high-speed operation.
