BlueOptics Q28-AOC-25M-MV-BO InfiniBand-kuituoptinen kaapeli 25 m OM3

The BlueOptics Q28-AOC-25M-MV-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends, designed for 100G high-speed transmissions over short distances. Constructed with OM3 multimode fibre (50 µm core) and flame-resistant LSZH sheathing, this 25-metre cable converts electrical signals to optical and back via built-in optical transceivers, providing a lightweight and flexible alternative to direct-attach twinax solutions for connections within or between adjacent server racks and high-performance computing equipment.

Advantages

The AOC design integrates I/O and O/E conversion in the QSFP28 housings to support 100GBASE-SR4 Ethernet and InfiniBand applications while reducing weight and improving flexibility compared with DAC cables. OM3 multimode fibre and a smaller bend radius deliver reliable short-reach performance. LSZH (halogen-free, low smoke) sheathing enhances fire-safety characteristics for data centre environments. Each cable is manufactured to MSA and industry specifications and tested for functionality prior to shipment.

Suitable for

• High-performance computing clusters and InfiniBand networks
• 100GBASE-SR4 Ethernet links within racks or between adjacent racks
• Data centre interconnects requiring low weight and high flexibility
• Short-reach connections where OM3 multimode fibre is appropriate

Key specifications

• Cable type: Active Optical Cable (AOC) with integrated optical transceivers
• Length: 25 metres
• Connector type: QSFP28 to QSFP28 (hot-pluggable)
• Fibre type: OM3 multimode fibre

• Sheathing: LSZH (halogen-free, low smoke)
• Compliance: manufactured to MSA and common industry standards (functional testing before shipment)

How to use

Ensure both host devices support QSFP28 interfaces and are powered down or follow hot-plug guidelines from the equipment vendor. Insert each QSFP28 connector into the corresponding QSFP28 port until it clicks into place; the built-in transceivers handle electrical-to-optical and optical-to-electrical conversion automatically. Verify link status and negotiate speeds through the host systems. For removal, follow vendor-recommended hot-unplug procedure or power-down sequence to avoid port or system interruptions.

Recommendations

Route the cable with attention to bend radius limits of OM3 multimode AOCs and avoid sharp bends, kinks, or crushing. Use cable management within racks to minimize stress and maintain airflow. Choose AOC over DAC where reduced weight and improved flexibility are required; select OM3 for short-reach 100G links, and confirm compatibility with your switches and NICs prior to deployment.
