## Summary description

The BlueOptics Q28-AOC-7M-AT-BO is a 7m InfiniBand fibre optic cable designed for high-speed data transfer. 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-7M-AT-BO InfiniBand fibre optic cable is a 7 m active optical cable (AOC) with QSFP28 connectors on both ends, designed for high-speed short-reach interconnects in data centers and high-performance computing environments. It uses OM3 multimode fibre with a 50 µm core diameter and supports 100GBASE-SR4 and InfiniBand style high-throughput links. The cable features LSZH (low smoke zero halogen) flame-resistant sheathing and a compact, lightweight construction that simplifies routing within racks and between adjacent racks.
Advantages
The active QSFP28-to-QSFP28 design integrates electrical-to-optical and optical-to-electrical conversion in the connector housings, enabling hot-pluggable operation and eliminating the need for separate transceivers. Compared with direct-attach twinax solutions, this AOC offers improved flexibility, reduced weight, smaller bend radius and a smaller overall diameter for easier cable management. Factory-tested components and compliance with common industry standards ensure consistent signal performance and reliable operation.
Suitable for
 Short-reach 100 Gbps links inside racks or between adjacent racks
 High-performance computing clusters requiring low-latency InfiniBand connectivity
 Data centre top-of-rack and server-to-switch interconnects
 Environments that prefer flame-retardant LSZH cabling for safety
Key specifications
 Cable type: Active Optical Cable (AOC) with QSFP28 connectors both ends
 Length: 7 meters
 Fibre type: OM3 multimode fibre
 Core diameter: 50 µm multimode
 Supported protocols: 100GBASE-SR4 and InfiniBand-compatible high-speed links
 Sheathing: LSZH (low smoke zero halogen), flame resistant
 Connector compatibility: QSFP28 form factor, MSA-compliant
 Physical attributes: lightweight, reduced diameter, small bend radius
How to use
Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on network switches, servers or host channel adapters. The connectors are hot-pluggable; ensure ports are powered and configured according to the equipment vendor's instructions before transmitting production traffic. Route the cable following standard data centre cable-management practices to avoid sharp bends and mechanical strain on the connector housings. No additional transceivers are required because optical/electrical conversion is integrated into the cable ends.
Usage recommendations
Use this AOC for short-distance high-bandwidth interconnects where weight, flexibility and small bend radius are priorities. Avoid exceeding the specified minimum bend radius and keep the LSZH jacket clean to maintain optical performance. Verify equipment compatibility with QSFP28 ports and supported 100G or InfiniBand modes before deployment.
