## Summary description

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

## Long description

The BlueOptics Q28-AOC-25M-EE-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) assembled with QSFP28 connectors on both ends for 100G high-speed short-range connections. Built with OM3 multimode fibre (50 µm core) and a 25 metre length, this AOC converts electrical signals to optical and back via integrated I/O O/E converters in the QSFP28 housings. The cable is intended for interconnections inside racks or between adjacent racks in data centres and high-performance computing environments, offering lower weight, greater flexibility and a smaller bend radius compared with passive twinax solutions.
Advantages
The active optical construction provides reliable 100GBASE-SR4 performance over short distances while remaining hot-pluggable and compliant with SFF/MSA and IEEE specifications for QSFP28 modules. The OM3 multimode fibre and LSZH (low smoke zero halogen) flame-resistant sheathing reduce fire risk and emissions. Compared with direct attach copper twinax, this QSFP28–QSFP28 cable offers reduced weight, improved flexibility, smaller diameter and better bend tolerance. Each unit is factory-new, function-tested and manufactured using industry-grade components and tested to recognised safety and environmental standards.
Suitable for
 100G connections within a single rack
 Inter-rack links between adjacent racks
 High-performance computing clusters and InfiniBand fabrics
 Data centre uplinks and switch-to-switch short-reach links
Key specifications
 Length: 25 metres
 Connector type: QSFP28 to QSFP28 (hot-pluggable)
 Fibre type: OM3 multimode fibre
 Core diameter: 50 µm
 Supported application: 100GBASE-SR4 / InfiniBand high-speed transmission
 Sheath: LSZH (low smoke, zero halogen), flame resistant
 Bend radius: designed for smaller bend radius than passive twinax
How to use
Install the QSFP28 connectors into compatible QSFP28 ports on switches, network adapters or other networking devices while the systems are powered as the cable is hot-pluggable. Ensure connector alignment and a secure seating until the latch engages. Route the cable to avoid excessive tight bends and sharp edges; respect the recommended bend radius specified by the equipment manufacturer. No separate transceivers are required because the O/E and E/O conversion is integrated in the connectors. If issues occur, reseat both ends and verify port configuration and link speed settings on connected devices.
Usage recommendations
For reliable operation, use the cable for short-reach 100G links within and between adjacent racks, avoid physical strain on connector ends, store coiled without tight loops, and perform compatibility checks with QSFP28 ports and switch firmware. Follow data centre cabling guidelines and safety rules for LSZH materials when routing through enclosed spaces.
