## Summary description

The BlueOptics Q28-AOC-7M-AO-BO is a 7m 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 environments.

## Long description

The BlueOptics Q28-AOC-7M-AO-BO InfiniBand/fibre optic cable 7m OM3 is a 7-metre active optical cable (AOC) with QSFP28 connectors on both ends, engineered for high-speed short-range connections in data centres and high-performance computing environments. This cable uses OM3 multimode fibre with a 50 µm core diameter and supports 100GBASE-SR4 Ethernet applications. The integrated transceiver modules inside the QSFP28 housings convert electrical signals to optical and back, enabling hot-pluggable, low-latency links between switches, servers and storage within or between adjacent racks.
Advantages
The BlueOptics AOC provides lower weight and greater flexibility compared to direct attach twinax (DAC) cables, with a smaller bend radius and reduced cable diameter. Its QSFP28 transceivers are manufactured to MSA and SFF/IEEE specifications for compatibility and consistent performance. The cable features LSZH (low smoke zero halogen) flame-resistant sheathing, and each unit is factory new and tested for quality and functionality. Components from established manufacturers are used and production complies with common industry standards such as CE and RoHS.
Suitable for
 High-density data centre interconnects within racks
 Connections between adjacent server or switch racks
 100GBASE-SR4 Ethernet links and InfiniBand short-range links
 High-performance computing clusters and storage fabrics
Key specifications
 Cable type: Active Optical Cable (AOC)
 Connector type: QSFP28 to QSFP28
 Length: 7 metres
 Fibre type: OM3 multimode fibre
 Core diameter: 50 µm
 Supported standard: 100GBASE-SR4 Ethernet (suitable for InfiniBand/high-speed links)
 Sheathing: LSZH (low smoke zero halogen), flame resistant
 Bend radius and diameter: reduced compared to DAC solutions (improved flexibility)
How to use
Install the BlueOptics QSFP28 to QSFP28 AOC by inserting each QSFP28 connector into compatible QSFP28 ports on network switches, servers or adapters. The cable is hot-pluggable; ensure both ends are securely seated until the connector latches. No external power is required beyond the host ports since the electrical/optical conversion is integrated. Verify the link status on connected devices and confirm supported speeds and lanes are negotiated correctly. Handle the cable by the connector housings and avoid sharp bends at the connector transition points.
Usage recommendations
For reliable operation, route the cable to avoid tight bends and mechanical strain, keep it clear of heat sources, and maintain proper port airflow. Use the 7 m length for intra-rack or adjacent-rack connections; for longer distances select an appropriate optical solution. Confirm device firmware and driver compatibility with QSFP28 AOCs and perform link testing after installation.
