## Summary description

The BlueOptics Q28-AOC-25M-PT-BO is a 25m InfiniBand fibre optic cable designed for high-speed data transmission. It features OM3 fibre type with a 50 µm core diameter and QSFP28 connectors on both ends, ensuring compatibility with modern networking equipment. Ideal for data centers and high-performance computing environments, this cable provides reliable connectivity and efficient data transfer over long distances.

## Long description

The BlueOptics Q28-AOC-25M-PT-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends designed for 100G high-speed short-reach links. It uses OM3 multimode fibre with a 50 µm core diameter and a 25 metre length suited for connections within racks or between adjacent racks. The integrated transceiver modules convert electrical signals to optical and back, providing a lightweight, flexible alternative to direct-attach twinax (DAC) cables while meeting SFF/MSA and IEEE interface specifications.
Advantages
This QSFP28 to QSFP28 AOC offers lower weight and greater flexibility compared with DAC solutions, as well as a smaller bend radius and reduced diameter. The built-in I/O and O/E conversion supports reliable 100GBASE-SR4 signalling over OM3 fibre. The cable is manufactured and tested to industry standards and comes with a flame-resistant LSZH sheath for halogen-free, low-smoke operation in case of fire. Components from established suppliers and factory testing ensure consistent performance and compatibility with modern high-performance networking equipment.
Suitable for
 Data centre top-of-rack and adjacent-rack 100G connections
 High-performance computing clusters and InfiniBand fabrics
 Server-to-switch and switch-to-switch short-reach links
 Environments requiring LSZH cabling for reduced smoke and halogen content
Key specifications
 Length: 25 metres
 Connector type: QSFP28 to QSFP28 (hot-pluggable)
 Fibre type: OM3 multimode
 Core diameter: 50 µm
 Supported data rate: 100G (100GBASE-SR4)
 Sheath: LSZH (flame resistant, halogen-free)
 Bend radius: optimized for reduced bend sensitivity compared with DAC
How to use
Install the BlueOptics QSFP28 to QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on your switch, server or HBA while the devices are powered according to your equipment guidelines. The cable is hot-pluggable and the integrated transceivers handle electrical-to-optical and optical-to-electrical conversion automatically. Route the cable to avoid tight bends below the recommended bend radius and secure it to rack management hardware as needed to prevent strain on connectors. Verify link status and speed in your devices’ management interfaces after connection.
Usage recommendations
Use this 25m OM3 AOC for short-reach 100G links inside racks or between adjacent racks. Choose LSZH cabling when low smoke and halogen-free materials are required. Avoid sharp bends and mechanical stress, and ensure both ends are fully seated in QSFP28 ports. For guaranteed interoperability and longevity, pair the cable with equipment that supports QSFP28 and 100GBASE-SR4 profiles and follow the vendor’s installation and ESD handling procedures.
