## Summary description

The BlueOptics Q28-AOC-25M-IA-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 applications.

## Long description

The BlueOptics Q28-AOC-25M-IA-BO is a 25 m active optical cable (AOC) with QSFP28 connectors on both ends, designed for 100G high-speed transmissions over short distances. It uses OM3 multimode fiber with a 50 µm core diameter and LSZH sheathing for reduced smoke and halogen-free behavior. The cable integrates built-in I/O and O/E converters that transform electrical signals to optical and back, enabling reliable interconnects inside racks or between adjacent racks in data centers and high-performance computing environments.
Advantages
The active optical design offers lower weight and greater flexibility compared to direct attach twinax (DAC) solutions while maintaining 100GBASE-SR4 compatibility. QSFP28 transceiver-style connectors are manufactured according to MSA, SFF and IEEE guidelines for interoperable plug-and-play operation. The OM3 multimode fiber and optimized bend radius improve signal integrity over the 25 m length, and LSZH sheathing reduces toxic emissions in case of fire. Each cable is factory-new and tested for quality and functionality to meet common industry standards.
Suitable for
 100G Ethernet interconnects within or between adjacent server racks
 High-performance computing clusters and InfiniBand-equipped systems
 Switch-to-switch or switch-to-server connections in data center topologies
 Short-reach optical uplinks where flexibility and reduced weight are required
Key specifications
 Length: 25 meters
 Connector type: QSFP28 to QSFP28 (active transceiver-style ends)
 Fiber type: OM3 multimode fiber
 Core diameter: 50 µm
 Supported standard: 100GBASE-SR4 / 100G transmission
 Sheath: LSZH (low smoke, zero halogen)
 Bend radius: optimized for smaller bend radius compared to twinax
How to use
Insert the QSFP28 connector ends into compatible QSFP28 ports on switches, NICs or host adapters until the latch secures. No separate transceiver modules are required since the cable contains integrated optical/electrical conversion. Ensure ports are powered down or follow hot-plug guidelines from the hardware vendor if inserting live. Verify link status and speed in host or switch management interfaces after connection. Route the cable to avoid sharp bends beyond the specified bend radius and secure it to prevent mechanical stress on the connectors.
Usage recommendations
Use this AOC for short-reach 100G links inside racks or between adjacent racks where reduced weight, improved flexibility and standards-based QSFP28 connectivity are desired. Avoid installing the cable where repeated extreme flexing or exposure to fluids, high temperatures or mechanical abrasion may occur; follow data center cabling practices and vendor hot-plug instructions for best results.
