## Summary description

The BlueOptics Q28-AOC-7M-CN-BO is a 7-meter InfiniBand fibre optic cable with OM3 fibre type. It features QSFP28 connectors on both ends and a core diameter of 50 µm, ensuring high-speed data transmission for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-7M-CN-BO InfiniBand fibre optic cable is a 7 metre active optical cable (AOC) with QSFP28 connectors on both ends and OM3 multimode fibre. Designed for short-range, high-speed interconnects in data centres and high-performance computing, this cable supports 100GBASE-SR4 Ethernet and provides converterized QSFP28 transceivers that transform electrical signals to optical and back for reliable 100 Gbit/s links between switches, servers and network appliances. The cable uses a 50 µm core diameter multimode fibre and a flame-retardant LSZH outer sheath to reduce smoke and halogen emission in case of fire.
Advantages
The active optical construction offers lower weight and greater flexibility compared with direct-attach twinax (DAC) solutions, together with a smaller bend radius and reduced cable diameter. QSFP28 transceiver modules are hot-pluggable and conform to SFF/MSA and IEEE conventions for interoperability. Each unit is factory-tested and supplied new, with components chosen from established manufacturers to support stable long-term operation and compliance with common industry safety and environmental norms.
Suitable for
 Short-range 100 Gbit/s connections within server racks or between adjacent racks
 High-performance computing cluster interconnects
 Top-of-rack or spine switch links requiring QSFP28 interfaces
 Environments where reduced weight and improved bend radius are needed
Key specifications
 Cable type: Active Optical Cable (AOC)
 Length: 7 metres
 Connector type: QSFP28 to QSFP28 (hot-pluggable)
 Supported standard: 100GBASE-SR4 Ethernet
 Fibre type: OM3 multimode
 Core diameter: 50 µm
 Sheath: LSZH (low smoke, zero halogen), flame resistant
 Performance: designed for high-speed, short-reach transmission with small bend radius
How to use
Install the BlueOptics QSFP28 to QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on the network devices until it latches. The integrated optical/electrical conversion is handled by the cable ends, so no additional transceivers are required. Verify link status through the host devices and ensure ports are configured for 100G operation as needed. To maintain signal integrity, avoid tight bends beyond the specified bend radius and route the cable inside racks or between adjacent racks for short-reach connections.
Usage recommendations
Handle the LSZH-sheathed AOC carefully during installation to avoid sharp bends and mechanical strain. Use cable management inside racks to prevent stress on connectors and maintain airflow. Confirm compatibility with device QSFP28 ports and verify that firmware or OS settings support 100GBASE-SR4 links.
