## Summary description

The BlueOptics Q28-AOC-7M-IA-BO is a 7m InfiniBand fibre optic cable featuring QSFP28 connectors. It utilizes OM3 fibre optic type with a core diameter of 50 µm, ensuring high-speed data transmission for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-7M-IA-BO InfiniBand fibre optic cable 7m QSFP28 is an active optical cable (AOC) designed for short-distance, high-speed connections between network devices. Built with OM3 multimode fibre (50 µm core) and QSFP28 to QSFP28 hot-pluggable transceivers, this 7 metre AOC supports 100GBASE-SR4 Ethernet and InfiniBand environments where reliable 100 Gbps class links are required inside racks or between adjacent racks. The cable features a flame-resistant LSZH outer sheath for reduced smoke and halogen-free behavior in environments with strict fire-safety requirements.
Advantages
The active optical design integrates I/O and O/E conversion in the QSFP28 ends, enabling electrical-to-optical signal conversion with lower weight and greater flexibility than equivalent direct-attach twinax (DAC) assemblies. The product follows SFF/MSA and IEEE-related specifications for QSFP28 transceiver form factors and is factory tested for quality and functionality prior to shipment. Compared to passive copper alternatives, this AOC offers a smaller bend radius, reduced diameter, and improved performance for short-reach, high-bandwidth links.
Suitable for
 100GBASE-SR4 Ethernet connections inside data centre racks
 InfiniBand high-performance computing interconnects
 Short-reach links between adjacent racks or equipment within the same rack
 Upgrades from twinax DAC to lighter, more flexible optical cabling
Key specifications
 Cable type: Active Optical Cable (AOC)
 Connector type: QSFP28 to QSFP28 (hot-pluggable)
 Length: 7 metres
 Fibre type: OM3 multimode fibre
 Core diameter: 50 µm
 Supported link standard: 100GBASE-SR4 / InfiniBand-compatible high-speed links
 Sheath: LSZH (low smoke, zero halogen) flame resistant
 Bend performance: small bend radius compared with twinax solutions
How to use
Ensure both devices to be connected support QSFP28 interfaces and are powered off or support hot-plug operations according to the device manual. Align each QSFP28 connector with the corresponding port and insert until the latch engages; the integrated transceiver modules perform the O/E and E/O conversions automatically. Verify link status on connected equipment and consult device diagnostics if link does not establish. Handle the cable by the connector housings where possible and avoid excessive bending beyond the manufacturer-specified radius.
Usage recommendations
Use the BlueOptics 7m QSFP28 AOC for short-distance, high-bandwidth connections inside racks or between neighbouring racks. Avoid routing near high-temperature sources, maintain gentle routing with bends above the minimum bend radius, and ensure compatibility with the host devices' QSFP28 ports and firmware versions. For environments requiring verified compliance, confirm device support for 100GBASE-SR4 or InfiniBand link modes and follow data centre cabling management practices.
