## Summary description

The BlueOptics Q28-AOC-25M-QN-BO is a 25m InfiniBand fibre optic cable featuring QSFP28 connectors. It utilizes OM3 fibre optic type with a core diameter of 50 µm, ensuring high-speed data transmission and reliability for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-25M-QN-BO InfiniBand fibre optic cable is a 25 metre QSFP28 to QSFP28 Active Optical Cable (AOC) designed for short-distance 100G high-speed connections within data centre racks or between adjacent racks. The cable uses OM3 multimode fibre with a 50 µm core diameter and an LSZH (low smoke, zero halogen) outer sheath. QSFP28 module ends integrate electrical-to-optical and optical-to-electrical conversion to support 100GBASE-SR4 Ethernet and InfiniBand applications while maintaining hot-pluggable compatibility with SFF and IEEE MSA-compliant ports.
Advantages
The AOC design provides lower weight, greater flexibility and a smaller bend radius compared with direct-attach twinax (DAC) solutions. Built-in I/O and O/E conversion at the QSFP28 connectors reduces the need for separate transceivers and ensures signal integrity over the 25 m link. The cable is manufactured to industry MSA standards and is factory tested for quality and functionality. LSZH sheathing reduces toxic and corrosive emissions in case of fire, supporting safer installations in confined environments.
Suitable for
 100GBASE-SR4 Ethernet links within and between adjacent server racks
 High-performance computing and InfiniBand fabric connections
 Top-of-rack and spine switch interconnects in data centres
 Short-reach connections where reduced weight and improved flexibility are required
Key specifications

How to use
Ensure both QSFP28 ports on the connected devices are powered down or follow hot-plug guidance from the equipment vendor, then insert the QSFP28 connector ends into the respective ports until they latch. Verify link status and negotiated speed on the host equipment. For removal, follow the vendor’s hot-plug or shutdown procedure, depress the connector latch and pull straight out to avoid stress on the fibre. Route the cable with gentle bends, respecting its minimum bend radius to avoid signal loss or mechanical damage.
Usage recommendations
Use the BlueOptics Q28-AOC-25M-QN-BO for short-reach 100G links where reduced weight and flexibility matter. Avoid tight bends and sharp kinks, keep fibres away from high-heat sources, and store or route cables in trays or bundles that prevent crushing. Verify device compatibility with QSFP28 AOC modules and confirm firmware/driver support for AOC modules if required by the host system.
