## Summary description

The BlueOptics Q28-AOC-25M-IX-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 enhances signal quality, making it suitable for data centers and enterprise networks.

## Long description

The BlueOptics Q28-AOC-25M-IX-BO InfiniBand fibre optic cable 25m OM3 is a 25-metre active optical cable (AOC) with QSFP28 connectors on both ends, intended for 100G high-speed transmissions over short distances. It uses OM3 multimode fibre with a 50 µm core diameter and LSZH (low smoke zero halogen) sheathing. The cable integrates optical-electrical conversion modules in the QSFP28 housings so it behaves as a hot-pluggable QSFP28-to-QSFP28 link compatible with SR4/100GBASE-SR4 applications and rack-to-rack connectivity within data centres and enterprise networks.
Advantages
The active optical construction provides lower weight and greater flexibility than direct-attach twinax solutions while maintaining 100G performance. Built-in I/O and O/E converters in the QSFP28 ends remove the need for separate transceivers, simplify installation and support hot-plug operation. OM3 multimode fibre and a 50 µm core diameter offer reliable signal quality for short-range high-bandwidth links. The LSZH jacket reduces halogen emissions and smoke in the event of fire, and components are manufactured to MSA/SFF and IEEE guidelines for interoperability.
Suitable for
High-density rack-to-rack connections within data centres
Short-reach 100G Ethernet interconnects (100GBASE-SR4)
InfiniBand high-performance computing clusters requiring QSFP28 links
Enterprise aggregation and spine-leaf fabric links inside server rooms
Key specifications
Cable type: Active Optical Cable (AOC) with integrated optical-electrical conversion
Length: 25 metres
Connector type: QSFP28 to QSFP28 (hot-pluggable)
Fibre type: OM3 multimode
Core diameter: 50 µm
Application: 100GBASE-SR4 / short-range 100G transmissions
Sheath: LSZH (low smoke zero halogen)
Compatibility: Designed to meet MSA/SFF and IEEE interoperability guidelines
How to use
Install the BlueOptics QSFP28-to-QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on your switches, NICs or InfiniBand adapters. Ensure both ends are fully seated and latched; the integrated O/E converters will negotiate link parameters automatically. No separate transceivers or fibre termination is required. Use the cable for short-distance links inside racks or between adjacent racks and avoid excessive bending beyond the recommended bend radius.
Usage recommendations
When routing the cable, maintain manufacturer-recommended bend radius and avoid sharp kinks to preserve OM3 multimode performance. Use within the specified short-reach distance for 100GBASE-SR4 applications and verify device compatibility with QSFP28 AOC modules. Keep connectors clean and protected during installation to ensure reliable link quality.
