## Summary description

The BlueOptics Q28-AOC-25M-CI-BO is a 25m InfiniBand fibre optic cable designed for high-speed data transmission. It features OM3 fibre type with a core diameter of 50 µm and QSFP28 connectors on both ends, ensuring reliable connectivity for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-25M-CI-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends designed for short-range 100G high-speed links. It uses OM3 multimode fibre with a 50 µm core diameter and integrates I/O and O/E conversion in the QSFP28 modules to deliver optical transmission between devices inside a rack or between adjacent racks. The cable features a flame-resistant LSZH outer jacket and is intended for high-performance computing and data centre interconnects where reduced weight, improved flexibility and a small bend radius are required.
Advantages
The product provides 100GBASE-SR4 compatible transmission over a 25 m reach while keeping lower weight and greater flexibility compared with direct-attach twinax solutions. QSFP28 transceiver connectors conform to MSA and SFF/IEEE form-factor standards and include built-in electrical-to-optical and optical-to-electrical conversion for hot-pluggable operation. The LSZH sheath reduces halogen release and smoke in case of fire. Each cable is factory new and tested for functionality and quality prior to shipment.
Suitable for
Interconnects between network switches, routers or servers within a rack
Connections between adjacent racks in data centres
High-performance computing clusters and InfiniBand environments
Short-range 100G Ethernet and SR4 optical links

Fibre type: OM3 multimode fibre
Core diameter: 50 µm
Application: 100GBASE-SR4 / InfiniBand high-speed transmission
Sheath: LSZH (low smoke zero halogen), flame resistant
Bend radius: designed for reduced bend radius compared with twinax
Weight: lower weight versus direct-attach twinax solutions
How to use
Install the BlueOptics QSFP28-to-QSFP28 active optical cable by inserting each QSFP28 module into the corresponding QSFP28 port on your compatible network device. Ensure devices are powered down or follow hot-plugging procedures recommended by the device manufacturer when connecting or removing the cable. Route the cable to avoid sharp bends and secure it within the rack to prevent strain on connectors. Verify link status on connected equipment and confirm negotiated speeds and lanes after installation.
Usage recommendations
Handle the AOC by the QSFP28 housings and avoid pulling on the fibre jacket. Maintain bend radii within the manufacturer's guidelines and avoid repeated tight bending. Use this 25 m OM3 AOC where short-range 100G links are required inside or between racks and where LSZH sheathing is preferred for reduced smoke and halogen emissions.
