BlueOptics 40G-AOC-QSFP15M-BO InfiniBand fibre optic cable 15 m QSFP

The BlueOptics 40G-AOC-QSFP15M-BO InfiniBand fibre optic cable 15 m QSFP is a 15-metre active optical cable designed to provide high-speed connectivity between QSFP ports in data centre and networking environments. It supports InfiniBand signalling and is intended for short to medium reach interconnects where consistent 40 Gbps-class data transfer and low latency are required. The cable integrates QSFP terminations and optical transmission in a single assembly to simplify installation and reduce the need for separate transceivers.

Advantages

This active optical cable delivers a stable 40 Gbps-class link with minimal signal loss over its 15 m length, reducing the need for additional repeaters or active electronics in the link. The integrated QSFP terminations simplify port-to-port connections and permit direct attachment to compatible switches, network adapters and storage devices. Its optical design reduces electromagnetic interference and lowers heat generation compared with equivalent copper assemblies.

Suitable for

• Interconnects between switches, routers and servers with QSFP ports
• High-performance computing clusters using InfiniBand fabrics
• Data centre top-of-rack and end-of-row linking at 40 Gbps range
• Storage area networks and backup systems requiring low-latency links

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP (quad small form-factor pluggable) on both ends
• Supported protocol: InfiniBand signalling at 40 Gbps class
• Length: 15 metres
• Transmission medium: multimode optical link integrated in cable assembly
• Latency: low-latency optical transmission suitable for HPC and storage traffic
• EMI immunity: optical transmission eliminates susceptibility to electromagnetic interference

How to use

Connect each QSFP termination to a compatible QSFP port on your network device or host adapter, ensuring the port supports InfiniBand or the targeted 40 Gbps interface. Verify link status indicators on both devices after insertion and confirm negotiated speed and lane configuration in device management tools. Use proper handling to avoid sharp bends or tensile stress on the cable and ensure sufficient airflow around connected equipment.

Recommendations

For reliable operation, route the cable with gentle curves and avoid bending below the manufacturer’s minimum bend radius. Use QSFP-compatible ports rated for InfiniBand 40 Gbps and check firmware or driver compatibility if link training does not complete. Store and handle the cable by its connector housings and avoid exposing terminations to dust; replace protective caps when not in use.
