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

The BlueOptics QSFP-AOC-3M-SO-BO InfiniBand fibre optic cable 3m Male/Male is a 3-metre active optical cable designed for high-bandwidth, low-latency links in data centres and high-performance computing environments. With QSFP form-factor connectors on both ends, this cable supports multi-lane InfiniBand links and delivers reliable optical transmission over a short reach without the need for separate transceivers. It is intended for direct device-to-device connections where secure, high-speed interconnects are required.

Advantages

This active optical cable offers high data throughput and low latency characteristics suitable for InfiniBand fabrics. The integrated optical transceivers within the cable eliminate the need for separate SFP/QSFP modules, simplifying installation and reducing component count. Its compact, flexible design allows for neat cable management in dense racks and switch arrays, while the fixed 3 metre length provides a predictable physical layout for short-range interconnects.

Suitable for

• Interconnects between InfiniBand switches and host adapters in data centres
• High-performance computing clusters requiring multi-lane connectivity
• Server-to-switch or switch-to-switch links within the same rack or adjacent racks
• Environments where integrated optical solutions reduce inventory and simplify deployments

Key specifications

• Connector type: QSFP to QSFP (male/male)
• Length: 3 metres
• Type: Active Optical Cable (AOC)
• Application: InfiniBand high-speed interconnects
• Form factor: QSFP (quad small form-factor pluggable)

How to use

For installation, insert each QSFP connector into the corresponding QSFP port on the devices to be linked, ensuring correct orientation and a secure mechanical fit. No external transceivers are required because the optical interfaces are built into the cable ends. After connection, verify link status on the connected devices and confirm expected link speed and lane configuration in the host or switch management interface. Route the cable to avoid sharp bends and secure it to maintain airflow and rack organisation.

Recommendations

Use this 3 m AOC for short-reach connections inside racks or between adjacent racks where InfiniBand throughput and low latency are required. Avoid exceeding the cable's bend radius and protect the connectors from dust when not in use. Check device compatibility for QSFP-based InfiniBand links before deployment.
