## Summary description

The BlueOptics Q28-AOC-7M-VA-BO is a 7-meter 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-VA-BO InfiniBand fibre optic cable is a 7-meter Active Optical Cable (AOC) with QSFP28 connectors on both ends and OM3 multimode fibre. Designed for high-speed short-range links in data centres and high-performance computing, this AOC converts electrical signals to optical and back on the integrated connector modules, enabling 100GBASE-SR4 class transmission over a flexible, lightweight assembly. The cable sheath is low-smoke zero-halogen (LSZH), providing reduced smoke and no halogen emissions in case of fire.
Advantages
This BlueOptics QSFP28 to QSFP28 AOC offers lower weight and greater flexibility compared with direct-attach twinax solutions while maintaining high signal integrity for 100G short-reach applications. Built-in I/O and O/E conversion in the connectors eliminates the need for separate transceivers, and adherence to MSA, SFF and IEEE guidelines ensures compatibility with standard QSFP28 ports. The OM3 50 μm core multimode fibre supports reliable multimode transmission and the LSZH jacket improves safety in confined or multi-rack environments.
Suitable for
Interconnects within server racks and between adjacent racks in data centres
High-performance computing clusters requiring InfiniBand or 100G Ethernet links
Short-reach switch-to-switch and switch-to-server connections using QSFP28 ports
Key specifications
Cable type: Active Optical Cable (AOC) with integrated optical-electrical conversion
Connector type: QSFP28 to QSFP28, hot-pluggable
Fibre type: OM3 multimode, core diameter 50 µm
Length: 7 meters
Supported standard: 100GBASE-SR4 / InfiniBand high-speed applications
Jacket material: LSZH (low smoke zero halogen), flame resistant
Design features: reduced bend radius and smaller diameter compared with DAC alternatives
How to use
Connect the QSFP28 plug on one end of the AOC into the QSFP28 port of your switch, server or HBA until it seats and the port latch engages. Route the cable along rack pathways avoiding sharp bends below the minimum bend radius to preserve optical performance. Plug the opposite QSFP28 connector into the corresponding port on the remote device. The integrated modules perform automatic electrical-to-optical and optical-to-electrical conversion; verify link status in your host or switch management interface and confirm port negotiation settings for 100G operation if required.
Usage recommendations
Maintain gentle cable bends and secure routing within racks to avoid stress on connectors. Use the 7 m length for intra-rack or adjacent-rack connections; for longer spans select a suitable AOC or transceiver plus fibre assembly. Confirm your equipment supports QSFP28 AOC modules and 100GBASE-SR4 or corresponding InfiniBand profiles before deployment.
