## Summary description

The BlueOptics Q28-AOC-25M-FR-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-FR-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) designed for 100G high-speed short-range connections. Featuring OM3 multimode fibre with a 50 µm core and QSFP28 connectors on both ends, this 25 metre AOC converts electrical signals to optical and back at the transceiver ends to support reliable 100GBASE-SR4 and InfiniBand data transmission between devices within or between adjacent racks. The cable uses a flame-resistant LSZH sheath for reduced smoke and halogen-free construction, and its QSFP28 modules conform to common MSA, SFF and IEEE specifications to ensure interoperability with compatible network and server equipment.
Advantages
This active optical cable offers lower weight and greater flexibility compared with direct-attach twinax solutions, enabling easier routing inside racks and tighter bend radii. Integrated I/O and O/E converters in the QSFP28 transceivers provide stable optical-electrical conversion without separate pluggable modules. The OM3 multimode fibre supports high-bandwidth 100G links over short distances while the LSZH outer jacket improves fire safety in data centre environments. Factory testing and the use of recognised component manufacturers help ensure consistent performance and long-term reliability.
Suitable for
100GBASE-SR4 Ethernet links within racks or between adjacent racks
High-performance computing and InfiniBand interconnects requiring 100G
Switch-to-switch, switch-to-server and high-density patch panel connections
Environments where reduced cable weight and tighter bend radius are required
Key specifications
Fibre type: OM3 multimode fibre
Core diameter: 50 µm
Connector type: QSFP28 to QSFP28 (integrated transceiver modules)
Length: 25 metres
Supported data rate: 100 Gbit/s
Application: 100GBASE-SR4 / InfiniBand short-range links
Jacket material: Low Smoke Zero Halogen (LSZH), flame resistant
Bend radius: smaller radius than typical twinax solutions (improved flexibility)
How to use
Install the cable by plugging each QSFP28 connector into the corresponding QSFP28 port on your switches, servers or adapters. The integrated transceiver modules are hot-pluggable; ensure ports are powered and configured for 100G operation as required by your equipment. Route the cable to avoid excessive mechanical stress and maintain the manufacturer-recommended minimum bend radius. No separate optical transceivers are required since conversion is performed within the AOC modules. Verify link status and perform functional tests after installation to confirm the connection operates at the expected speed.
Usage recommendations
Store and handle the BlueOptics AOC with care to avoid sharp bends or crushing. Use cable management within racks to prevent strain on connectors, and keep the LSZH jacket free of contaminants. For optimal performance, match the cable to compatible QSFP28 ports and ensure firmware or driver support for 100G links in your networking equipment.
