## Summary description

The BlueOptics Q28-AOC-25M-MA-BO is a 25m InfiniBand fibre optic cable designed for high-speed data transfer. It features OM3 fibre type and QSFP28 connectors on both ends, ensuring reliable performance and compatibility with various networking equipment. The 50 µm core diameter allows for efficient signal transmission, making it ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-25M-MA-BO InfiniBand fibre optic cable 25m OM3 is a 25-metre Active Optical Cable (AOC) with QSFP28 connectors on both ends, designed for 100G high-speed transmissions over short distances. It uses OM3 multimode fibre with a 50 µm core diameter and integrates optical-electrical conversion in the QSFP28 modules. The cable features LSZH (low smoke zero halogen) sheathing and is intended for interconnections within racks or between adjacent racks in data centers and high-performance computing environments.
Advantages
This QSFP28-to-QSFP28 AOC provides flexible, lightweight cabling with a smaller bend radius compared to direct-attach twinax solutions. The built-in I/O and O/E converters in the transceiver housings enable hot-pluggable 100GBASE-SR4 operation and stable optical signal transmission over the 25 m distance. The cable is manufactured to industry MSA, SFF and IEEE guidelines and is produced using components from established vendors to ensure consistent performance, reduced weight and improved thermal properties. The LSZH jacket reduces halogen release and smoke in the event of a fire.
Suitable for
 Short-reach 100G interconnects inside racks
 Connections between adjacent server or switch racks
 High-performance computing cluster links
 Data centre switch-to-switch or switch-to-server links
Key specifications
 Cable type: Active Optical Cable (AOC) with integrated transceiver modules
 Connector type: QSFP28 to QSFP28 (hot-pluggable)
 Length: 25 metres
 Fibre type: OM3 multimode fibre
 Core diameter: 50 µm multimode core
 Standard compatibility: 100GBASE-SR4 Ethernet
 Sheath material: LSZH (low smoke, zero halogen)
 Bend radius: smaller bend radius than typical twinax solutions (AOC design)
How to use
Install the BlueOptics Q28-AOC-25M-MA-BO by inserting each QSFP28 connector into the corresponding QSFP28 port on switches, servers or network adapters. The cable is hot-pluggable; ensure that ports support QSFP28 modules and 100GBASE-SR4 operation. Route the cable following recommended bend radius guidelines and avoid tight kinks; secure the cable to rack infrastructure if necessary to prevent strain on connectors. No separate transceiver modules or patch panels are required because the optical-electrical conversion is integrated into the cable ends.
Usage recommendations
Use this AOC for short-distance 100G links inside racks or between adjacent racks. Confirm compatibility with host devices' QSFP28 ports and check firmware or vendor compatibility lists if applicable. Handle the QSFP28 housings carefully, maintain minimum bend radius, and keep connector dust caps in place when connectors are not mated to protect optical interfaces.
