BlueOptics 100FRRF0500-BO InfiniBand fibre optic cable 50 m QSFP28

The BlueOptics 100FRRF0500-BO InfiniBand fibre optic cable 50 m QSFP28 is a 50-metre active optical cable (AOC) with QSFP28-to-QSFP28 male connectors designed for high-speed data links in data centres and networking environments. Engineered for 100GBASE-SR4 and InfiniBand applications, the cable integrates a transmitter and receiver module at each end and uses multimode fibre to support short-reach 100 Gbit/s connections over 50 metres while avoiding electromagnetic interference inherent to copper links.

Advantages

This BlueOptics AOC is manufactured to MSA-compliant QSFP28 interface standards and is compatible with hardware that supports 100GBASE-SR4 and related Intel-compatible implementations. The integrated transceivers simplify installation by delivering a pre-assembled optical link without the need for patching or cleaning patch cords, reducing attenuation points. The cable supports digital diagnostics monitoring (DDM/DOM) for real-time readout of supply voltage, laser bias current, transmit output power, received input power and temperature when used in equipment that exposes DDM/DOM data.

Suitable for

• 100 Gbit/s short-reach links in data centres (switch-to-switch)
• High-performance InfiniBand connections for compute clusters
• Interconnects between routers, switches and storage systems

Key specifications

• Length: 50 metres
• Connector type: QSFP28 male to QSFP28 male
• Rated protocol: 100GBASE-SR4 / InfiniBand-compatible 100G applications
• Media: multimode fibre with integrated active optical transceivers
• Diagnostics: DDM/DOM support for real-time monitoring (requires host support)

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on the network devices ensuring proper alignment and secure seating. Verify that the host devices support 100GBASE-SR4 or InfiniBand at the intended speed and that any required firmware or driver settings permit use of third-party AOCs. If DDM/DOM information is required, confirm that the equipment exposes diagnostic registers and monitor the reported parameters through the management interface.

Recommendations

Avoid sharp bends and excessive pulling force on the cable; maintain minimum bend radii specified by multimode fibre best practices and route the cable to prevent kinks. Ensure QSFP28 ports are powered down or handled according to device guidelines when inserting or removing the AOC. For reliable diagnostics, use hardware and software that support DDM/DOM access.
