## Summary description

The BlueOptics Q28-AOC-25M-IB-BO is a 25m InfiniBand/fibre optic cable designed for high-speed data transmission. It features OM3 fibre optic 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-IB-BO is a 25 m active optical cable (AOC) with QSFP28 connectors on both ends, designed for 100G high-speed transmissions in data centers and high-performance computing environments. It uses OM3 multimode fibre with a 50 µm core diameter and an LSZH (low-smoke, zero-halogen) outer sheath for reduced smoke and no halogen emissions in case of fire. The built-in optical-electrical I/O converters in the QSFP28 transceiver housings enable reliable conversion between electrical and optical signals for connections within racks or between adjacent racks.
Advantages
The BlueOptics AOC offers lighter weight and greater flexibility compared with direct attach twinaxial (DAC) solutions, with a smaller bend radius and reduced cable diameter. QSFP28 transceiver connectors are manufactured to MSA, SFF and IEEE guidelines and include factory testing to ensure functionality. The cable is intended for 100GBASE-SR4 Ethernet applications and is produced from components that comply with CE, RoHS and recognised industrial test standards.
Suitable for
 Interconnects within server racks and between adjacent racks in data centers
 100GBASE-SR4 Ethernet links and InfiniBand high-speed connections
 High-performance computing (HPC) clusters and storage area networks (SAN)
 Short-reach optical links requiring LSZH sheathing
Key specifications
 Length: 25 m
 Connector type: QSFP28 to QSFP28 (active optical transceiver ends)
 Fibre type: OM3 multimode fibre
 Core diameter: 50 µm
 Data rate: designed for 100 G (100GBASE-SR4, InfiniBand-compatible)
 Sheath: LSZH (low smoke, zero halogen)
 Bend radius: smaller radius compared with typical DAC solutions (improved flexibility)
How to use
Inspect both QSFP28 connectors and the cable sheath for visible damage before installation. Insert each QSFP28 transceiver end into compatible QSFP28 ports until the connector latch engages, taking care to align the keyed housing correctly. The AOC is hot-pluggable; hot-swap the cable when required by following the host device manufacturer’s procedures. Route the cable to avoid sharp bends and stress points, maintain recommended bend radii, and secure the cable inside racks to prevent strain on connectors.
Usage recommendations
Use this BlueOptics AOC for short-reach 100G links where reduced weight, improved flexibility and LSZH sheathing are required. Verify compatibility with QSFP28 ports and firmware on switches or host adapters, and follow data center cabling best practices for routing, bend radius and strain relief to maintain signal integrity and long-term reliability.
