Cavo in fibra ottica InfiniBand BlueOptics XLAOCBL5-BO 5 m QSFP

The BlueOptics XLAOCBL5-BO InfiniBand fibre optic cable 5 m QSFP is an active optical cable (AOC) with QSFP-to-QSFP connectors designed for 40GBASE-SR4 applications. The pre-assembled 5 metre multimode fibre link integrates a transmitter and receiver in each QSFP plug to enable full-duplex optical transmission at data centre and high-performance computing speeds. The cable follows MSA-compliant QSFP AOC specifications to ensure mechanical and electrical interoperability with devices that support QSFP 40G connections.

Advantages

This 5 m BlueOptics AOC provides a plug-and-play fibre connection that is immune to electromagnetic interference and eliminates the need for separate patch cords or manual fibre termination. Built to MSA standards and using high-quality optical and electronic components, the cable supports up to 40 Gbps links with low latency and stable signal integrity. Integrated digital diagnostic monitoring (DDM/DOM) offers real-time telemetry for supply voltage, laser bias, output and input power, and temperature, simplifying troubleshooting and remote monitoring.

Suitable for

• Interconnects between QSFP ports on switches and routers within racks
• High-performance computing clusters and InfiniBand fabrics
• Storage systems and SAN connectivity requiring 40 G optical links
• Short-reach data centre spine and leaf connections up to 5 m

Key specifications

• Form factor: QSFP to QSFP active optical cable
• Length: 5 metres
• Data rate: up to 40 Gbps (40GBASE-SR4 applications)
• Fibre type: multimode (AOC with integrated optical transceivers)
• Monitoring: Digital Diagnostic Monitoring (DDM/DOM) per SFF-8472
• Compliance: QSFP AOC MSA mechanical/electrical compatibility; CE and RoHS conformity

How to use

Connect the QSFP plugs into compatible QSFP ports on network switches, routers or storage devices while the systems are powered according to manufacturer guidelines. The cable provides automatic optical link negotiation following the host hardware protocol; if DDM/DOM telemetry is required, enable or verify support in the host device to read diagnostic parameters. No additional fibre cleaning or patching is necessary thanks to the pre-assembled AOC design.

Recommendations

Verify that the target hardware officially supports QSFP 40G AOC modules and that the port firmware accepts third-party AOCs. Use the cable within the specified 5 m length for optimal performance, avoid tight bending radii near the connectors, and confirm DDM/DOM compatibility on the host for access to diagnostic data.
