## Summary description

The BlueOptics Q28-AOC-7M-CP-BO is a 7m InfiniBand fibre optic cable designed for high-speed data transmission. It features OM3 fibre type, QSFP28 connectors on both ends, and a core diameter of 50 µm, making it ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-7M-CP-BO InfiniBand fibre optic cable 7m OM3 is a factory-new active optical cable (AOC) featuring QSFP28 connectors on both ends and OM3 multimode fibre with a 50 µm core diameter. Designed for short-reach, high-speed interconnects within racks or between adjacent racks, this 7 metre AOC converts electrical signals to optical and back again inside the QSFP28 housings to support 100GBASE-SR4 Ethernet and similar InfiniBand links. The cable uses flame-resistant LSZH sheathing for reduced smoke and halogen-free construction and is manufactured to recognized industry MSA, SFF and IEEE guidelines. Each unit is tested before shipment to ensure functional conformity.
Advantages
The active optical design provides lower weight and greater flexibility than passive twinax solutions while maintaining hot-pluggable QSFP28 connectivity. Built-in electrical-to-optical and optical-to-electrical conversion in the QSFP28 ends enables reliable 100 Gb/s transmission over OM3 multimode fibre. The smaller bend radius and reduced cable diameter compared to direct-attach copper improve cable management in dense rack environments. LSZH sheathing reduces hazardous emissions in case of fire and the cable is manufactured and tested according to established industrial standards for compatibility and longevity.
Suitable for
High-density data centre rack-to-rack 100 Gb/s interconnects
Short-reach InfiniBand links in HPC clusters
Top-of-rack to adjacent rack connections
Switch-to-switch and switch-to-server connections requiring QSFP28 ports
Key specifications
Length: 7 metres
Connector type: QSFP28 to QSFP28 (active optical cable)
Fibre type: OM3 multimode
Core diameter: 50 µm
Supported interface: 100GBASE-SR4 / InfiniBand high-speed links
Sheath: LSZH (low smoke, halogen free)
Cable form factor: Active Optical Cable with I/O O/E conversion in connectors
How to use
Insert each QSFP28 connector into compatible QSFP28 ports on network switches, servers or InfiniBand adapters until the latch engages. The cable is hot-pluggable; power cycling is not required in most environments. Ensure that connected devices support 100GBASE-SR4 or the equivalent InfiniBand link speed and that port settings match the expected data rate and lane configuration. Maintain gentle bend radii and avoid tight kinks; the active transceivers will handle the electrical/optical conversion automatically once the link is established.
Usage recommendations
For reliable performance, install the cable in managed cable runs with gentle curves and avoid compressing the LSZH jacket. Do not exceed recommended bend radii and keep transceiver ends free of dust—use protective caps when the cable is not connected. Verify compatibility with device firmware and QSFP28 port types before deployment and test links after installation.
