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

The BlueOptics Q28-AOC-25M-LE-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends for 100G high-speed transmissions over short distances. Designed for intra-rack and adjacent-rack connections, this 25 meter OM3 cable converts electrical signals to optical and back again within the connector modules, providing a lightweight and flexible alternative to passive twinax DACs. The cable features LSZH flame-resistant sheathing and is built to follow MSA, SFF and IEEE requirements for compatible QSFP28 operation.

Advantages

The active optical design reduces weight and increases flexibility compared with direct-attach twinax cables while maintaining 100GBASE-SR4 Ethernet performance. QSFP28 transceiver connectors include built-in electrical-to-optical and optical-to-electrical conversion for hot-pluggable operation. The OM3 multimode fibre and optimized bend radius improve signal integrity in dense cabling environments. Manufacturing and pre-shipment testing follow industry standards to ensure consistent functionality and durability.

Suitable for

• High-performance computing clusters and InfiniBand connectivity
• 100GBASE-SR4 Ethernet links within racks or between adjacent racks
• Data center top-of-rack and aggregation layer connections
• Server-to-switch and switch-to-switch short-reach links

Key specifications

• Cable type: Active Optical Cable (AOC) with QSFP28 to QSFP28 connectors
• Length: 25 meters
• Fibre type: OM3 multimode
• Supported data rate: 100 Gbps (100GBASE-SR4 compatible)
• Sheathing: LSZH (low smoke, zero halogen) flame resistant
• Connector features: built-in electrical-to-optical and optical-to-electrical conversion, hot-pluggable
• Standards compliance: manufactured to MSA/SFF/IEEE-related formfactor specifications and industry norms

How to use

Install the QSFP28 connectors into compatible QSFP28 ports on switches, network adapters or servers, ensuring proper alignment and secure seating. The cable requires no separate transceiver modules because conversion occurs inside the QSFP28 connector assemblies. Use the cable for short-reach 100G links within racks or between adjacent racks; avoid tight bends and secure the cable to prevent stress at connector interfaces. Verify link status and speed on connected devices after insertion to confirm proper operation.

Recommendations

For reliable operation, route the cable to maintain bend radii within manufacturer guidelines, avoid exposure to direct heat sources or mechanical strain, and confirm compatibility with device QSFP28 ports. Use in environments where LSZH sheathing is required for reduced smoke and halogen emissions.
