## Summary description

The BlueOptics Q28-AOC-25M-PA-BO is a 25m InfiniBand fibre optic cable designed for high-speed data transmission. It features OM3 fibre type and QSFP28 connectors on both ends, ensuring optimal performance for data centers and networking applications. With a core diameter of 50 µm, this cable provides reliable connectivity and is suitable for various high-bandwidth applications.

## Long description

The BlueOptics Q28-AOC-25M-PA-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends designed for 100G high-speed short-reach links. With a 25 metre length and OM3 multimode fibre (50 µm core), this AOC converts electrical signals to optical and back inside its QSFP28 modules to enable reliable 100GBASE-SR4 and InfiniBand connectivity between devices in the same rack or adjacent racks. The cable uses a halogen-free LSZH sheath for reduced smoke and toxicity in case of fire and offers increased flexibility and lower weight compared with direct-attach twinax solutions.
Advantages
The integrated QSFP28 transceiver modules provide hot-pluggable, plug-and-play operation and comply with MSA, SFF and relevant IEEE specifications for form factor and interoperability. OM3 multimode fibre with a 50 µm core supports high-bandwidth short-reach transmission while the active conversion inside the cable ensures stable signal integrity at 100 Gbps. The LSZH outer jacket improves safety in enclosed environments, and the AOC design delivers a smaller bend radius and reduced weight versus DAC alternatives.
Suitable for
 Server-to-switch and switch-to-switch interconnects within racks
 Short-distance 100G Ethernet (100GBASE-SR4) links
 High-performance computing and InfiniBand fabrics
 Data centre top-of-rack and adjacent-rack cabling
Key specifications
 Cable type: Active Optical Cable (AOC) with QSFP28 to QSFP28 connectors
 Length: 25 metres
 Fibre type: OM3 multimode, 50 µm core diameter
 Supported link speed: 100 Gbit/s (100GBASE-SR4 / InfiniBand high-speed)
 Sheath: LSZH (low smoke, zero halogen)
 Bend radius: reduced compared with DAC; designed for tight routing in racks
 Hot-pluggable connectors with integrated electrical-to-optical and optical-to-electrical conversion
How to use
Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on your switches, routers or network adapters until the module seats and latches. No external transceivers are required because the conversion electronics are built into the cable ends. Ensure both ends are connected to compatible QSFP28 ports configured for 100G operation and verify link status via your devices' management interfaces. Route the cable to avoid sharp bends below the specified minimum bend radius and secure it within the rack to prevent strain on the connectors.
Usage recommendations
Use this 25m OM3 AOC for short-range 100G and InfiniBand interconnects inside racks or between adjacent racks where flexibility, reduced weight and adherence to LSZH safety standards are required. Avoid repeated insertion/removal cycles beyond manufacturer recommendations and maintain bend radius to preserve optical performance. Verify compatibility with host ports that support QSFP28 modules and 100GBASE-SR4 or equivalent InfiniBand signalling.
