BlueOptics Q28-AOC-50M-AT-BO InfiniBand fibre optic cable 50m QSFP28 Male

The BlueOptics Q28-AOC-50M-AT-BO InfiniBand fibre optic cable 50m QSFP28 Male is a 50-metre active optical cable (AOC) with QSFP28 connectors on both ends designed for high-speed short-reach links. It supports 100G data transmission over multimode fibre using a QSFP28-to-QSFP28 electrical and optical interface that follows MSA guidelines. The cable integrates optical transmitters and receivers and includes digital diagnostics monitoring (DDM/DOM) for real-time reporting of supply voltage, laser bias current, transmit power, receive power and temperature when supported by host hardware.

Advantages

The BlueOptics 50 m QSFP28 AOC provides a pre-assembled fibre link that avoids patching and minimizes attenuation from patch cords. Compliance with QSFP28 MSA standards ensures interoperability with equipment that supports QSFP28 AOC modules. Built-in DDM/DOM simplifies troubleshooting and remote monitoring of optical parameters. The all-in-one AOC design reduces electromagnetic interference concerns typical for copper cabling and enables consistent short-reach 100G connections in dense environments such as racks and data center rows.

Suitable for

• Short-reach 100G connections between switches and routers in data centers
• High-performance computing (HPC) clusters and InfiniBand fabric links
• Interconnecting storage systems and aggregation hardware within the same room or adjacent rooms
• Environments that require low-latency, high-bandwidth links without patch panels

Key specifications

• Length: 50 metres
• Connector type: QSFP28 to QSFP28 (male)
• Transmission rate: 100 Gbit/s (100GBASE-SR4 / QSFP28 AOC compliant)
• Fibre type: multimode optical link (AOC with integrated transceivers)
• Monitoring: Digital Diagnostics Monitoring / Digital Optical Monitoring (DDM/DOM) supported (dependent on host support)
• Compliance: QSFP28 AOC MSA mechanical/electrical/functional compliance

How to use

Install the BlueOptics Q28-AOC-50M-AT-BO by inserting the QSFP28 plugs into compatible QSFP28 ports on your networking devices, taking care to follow the host vendor’s insertion and extraction procedures. Ensure connected devices support QSFP28 AOC modules and, if you require diagnostic data, confirm the host system exposes DDM/DOM parameters. Route the cable to avoid sharp bends and mechanical strain; keep bend radius within manufacturer guidelines for multimode fibre AOCs. No additional patch cords or fibre polishing is required because the cable is factory-terminated.

Recommendations

For reliable operation, use this 50 m QSFP28 AOC within typical data centre ambient conditions and avoid environments with excessive vibration or temperatures outside the equipment specifications. Confirm compatibility with your switch, router or storage platform prior to deployment and, for initial rollouts, consider testing with a sample unit to verify full functionality and DDM/DOM readouts on your specific hardware.
