BlueOptics Q28-AOC-7M-IX-BO cable de fibra óptica InfiniBand 7m QSFP28

The BlueOptics Q28-AOC-7M-IX-BO InfiniBand fibre optic cable 7m QSFP28 is a factory-new active optical cable (AOC) designed for high-speed short-range connections between QSFP28 ports. Built with OM3 multimode fibre (50 µm core) and QSFP28-to-QSFP28 pluggable transceivers, this 7-metre cable supports 100GBASE-SR4 Ethernet and InfiniBand interconnects inside racks or between adjacent racks. The cable features a flame-resistant LSZH outer jacket for reduced smoke and no halogen release in the event of fire, while integrated electrical-to-optical and optical-to-electrical conversion enables lightweight, flexible, hot-pluggable connectivity compared with passive twinax solutions.

Advantages

The BlueOptics AOC provides lower weight and greater flexibility than direct-attach twinax cables, with a smaller bend radius and reduced diameter that simplify cable routing in dense rack environments. QSFP28 transceiver ends conform to MSA, SFF and IEEE specifications, and the cable assembly is factory-tested to ensure functionality. The LSZH sheathing improves safety in confined spaces and the use of branded photonics components supports long-term signal stability and predictable performance.

Suitable for

• Short-range high-speed server-to-switch or switch-to-switch connections within or between adjacent racks
• 100GBASE-SR4 Ethernet and InfiniBand high-performance computing links
• Data centre top-of-rack and leaf-spine network deployments requiring QSFP28 ports
• Environments where low smoke, halogen-free cabling is required

How to use

Inspect both QSFP28 ports and the BlueOptics cable connectors for debris before insertion. Align the QSFP28 module latch and insert the cable end gently into the QSFP28 port until it clicks into place. The integrated I/O converters handle signal conversion automatically; no separate transceiver modules are required. For removal, depress the latch and withdraw the connector straight out to avoid stressing the fibre. Use supported QSFP28 ports and verify link status via host or switch management interfaces after connecting.

Recommendations

Route the cable to avoid tight bends and maintain the manufacturer’s minimum bend radius. Keep AOC connectors covered when not in use to avoid contamination. Use the cable for short-range high-speed links inside racks or between adjacent racks as intended; do not attempt field repair of the active optical assembly. Follow equipment vendor guidance on supported cable types and link configuration for optimal interoperability.
