## Summary description

The BlueOptics Q28-AOC-25M-PS-BO is a 25m InfiniBand fibre optic cable designed for high-speed data transfer. It features OM3 fibre type with a core diameter of 50 µm and QSFP28 connectors on both ends, ensuring reliable connectivity for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-25M-PS-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) built for short-distance 100G high-speed connections. With QSFP28 connectors on both ends and OM3 multimode fibre (50 µm core), the cable converts electrical signals to optical and back in integrated transceiver modules, providing reliable links between devices inside racks or between adjacent racks. The cable features a flame-resistant LSZH outer sheath and is factory-tested for functionality and compliance with recognised industrial standards.
Advantages
The AOC design offers reduced weight and improved flexibility compared with direct attach twinax (DAC) solutions while maintaining 100GBASE-SR4-compatible performance. Built-in I/O and O/E converters in the QSFP28 connector housings ensure signal conversion and compatibility with QSFP28 ports. The OM3 multimode fibre and smaller bend radius improve routing in dense rack environments. The product is assembled from high-quality components and is tested against MSA, CE and RoHS related criteria.
Suitable for
 Short-range 100G connections inside data centre racks
 Inter-rack links between adjacent cabinets in high-performance computing
 High-throughput InfiniBand or 100G Ethernet uplinks and switch interconnects
 Server-to-switch and switch-to-switch connections where reduced weight and greater flexibility are required
Key specifications
 Length: 25 meters
 Connector type: QSFP28 to QSFP28
 Fibre type: OM3 multimode, 50 µm core diameter
 Supported data rate: 100 G (100GBASE-SR4 / InfiniBand high-speed transmission)
 Sheathing: LSZH (low smoke zero halogen), flame resistant
 Cable type: Active Optical Cable (AOC) with integrated transceivers
 Bend performance: smaller bend radius compared to DAC solutions
How to use
Connect each QSFP28 connector to the corresponding QSFP28 port on network equipment such as switches, routers or host adapters. The cable is hot-pluggable; insert or remove connectors while devices are powered on according to the hardware vendor's hot-swap guidance. Ensure both ends are seated fully to enable the integrated transceiver modules to negotiate the link and establish the 100G connection. Avoid sharp bends and prevent crushing to preserve optical performance and mechanical integrity.
Usage recommendations
Route the cable inside rack channels or management trays to minimize stress and maintain the recommended bend radius. Verify compatibility with the intended QSFP28 ports and check firmware or driver requirements for 100G operation when connecting to host adapters or switch modules. Inspect connector ends before insertion and keep dust caps in place when not in use.
