## Summary description

The BlueOptics Q28-AOC-25M-LE-BO is a 25m InfiniBand fibre optic cable designed for high-speed data transfer. It features OM3 fibre type and QSFP28 connectors on both ends, ensuring reliable performance and compatibility with various devices. Ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-25M-LE-BO InfiniBand fibre optic cable 25m OM3 is an active optical cable (AOC) with QSFP28 connectors on both ends for 100G high-speed transmissions over short distances. Designed for intra-rack and adjacent-rack connections, this 25 meter OM3 cable converts electrical signals to optical and back again within the connector modules, providing a lightweight and flexible alternative to passive twinax DACs. The cable features LSZH flame-resistant sheathing and is built to follow MSA, SFF and IEEE requirements for compatible QSFP28 operation.
Advantages
The active optical design reduces weight and increases flexibility compared with direct-attach twinax cables while maintaining 100GBASE-SR4 Ethernet performance. QSFP28 transceiver connectors include built-in electrical-to-optical and optical-to-electrical conversion for hot-pluggable operation. The OM3 multimode fibre and optimized bend radius improve signal integrity in dense cabling environments. Manufacturing and pre-shipment testing follow industry standards to ensure consistent functionality and durability.
Suitable for
 High-performance computing clusters and InfiniBand connectivity
 100GBASE-SR4 Ethernet links within racks or between adjacent racks
 Data center top-of-rack and aggregation layer connections
 Server-to-switch and switch-to-switch short-reach links
Key specifications
 Cable type: Active Optical Cable (AOC) with QSFP28 to QSFP28 connectors
 Length: 25 meters
 Fibre type: OM3 multimode
 Supported data rate: 100 Gbps (100GBASE-SR4 compatible)
 Sheathing: LSZH (low smoke, zero halogen) flame resistant
 Connector features: built-in electrical-to-optical and optical-to-electrical conversion, hot-pluggable
 Standards compliance: manufactured to MSA/SFF/IEEE-related formfactor specifications and industry norms
How to use
Install the QSFP28 connectors into compatible QSFP28 ports on switches, network adapters or servers, ensuring proper alignment and secure seating. The cable requires no separate transceiver modules because conversion occurs inside the QSFP28 connector assemblies. Use the cable for short-reach 100G links within racks or between adjacent racks; avoid tight bends and secure the cable to prevent stress at connector interfaces. Verify link status and speed on connected devices after insertion to confirm proper operation.
Usage recommendations
For reliable operation, route the cable to maintain bend radii within manufacturer guidelines, avoid exposure to direct heat sources or mechanical strain, and confirm compatibility with device QSFP28 ports. Use in environments where LSZH sheathing is required for reduced smoke and halogen emissions.
