## Summary description

The BlueOptics Q28-AOC-7M-FR-BO is a 7m InfiniBand fibre optic cable designed for high-speed data transfer. It features OM3 fibre type and QSFP28 connectors, ensuring efficient connectivity for data centers and high-performance computing environments.

## Long description

The BlueOptics Q28-AOC-7M-FR-BO InfiniBand Fibre Optic Cable 7m OM3 QSFP28 is an active optical cable (AOC) designed for short-range, high-speed interconnects in data centers and high-performance computing environments. This 7 metre QSFP28-to-QSFP28 cable uses OM3 multimode fibre and integrated optical/electrical conversion to support 100GBASE-SR4 Ethernet and InfiniBand link modes while offering reduced weight and greater flexibility compared with direct-attach twinax solutions. The cable features flame-resistant LSZH sheathing for low smoke and halogen-free behaviour and is manufactured to SFF/MSA and relevant IEEE specifications for compatibility with equipment supporting QSFP28 interfaces.
Advantages
The BlueOptics AOC provides optical signal transmission with built-in I/O and O/E converters in each QSFP28 connector, enabling reliable 100 Gbps links without external transceivers. Its active optical design yields a smaller bend radius, lower weight and greater flexibility compared with DAC cables, simplifying routing inside racks and between adjacent racks. The LSZH jacket reduces fire-related emissions, and factory testing ensures each cable is delivered new and verified for functionality and interoperability.
Suitable for
 High-performance computing clusters and InfiniBand interconnects
 100GBASE-SR4 Ethernet links within and between server racks
 Top-of-rack and adjacent-rack network connections requiring QSFP28 ports
 Environments where reduced cable weight and tighter bend radius are needed
Key specifications
 Form factor: QSFP28 to QSFP28 active optical cable
 Length: 7 metres
 Fibre type: OM3 multimode
 Transmission: Designed for 100 Gbps (100GBASE-SR4 / InfiniBand high-speed links)
 Sheath: LSZH (low smoke, zero halogen), flame resistant
 Connector features: Built-in optical/electrical conversion (hot-pluggable)
 Compliance: Manufactured to SFF/MSA and common industry specifications for QSFP28 interoperability
How to use
Connect one QSFP28 connector to the QSFP28 port of the source device and the other QSFP28 connector to the destination device. Ensure both ports support the intended 100G or InfiniBand link mode before hot-plugging. Route the cable with attention to the recommended bend radius to preserve optical performance and avoid sharp bends. Because the cable is active and hot-pluggable, no additional transceivers are required; the integrated converters handle the optical-electrical conversion automatically when both ends are connected and the link is negotiated.
Usage recommendations
Use this AOC for short-range interconnects inside racks or between adjacent racks where 100G capacity is required. Avoid exceeding the specified bend radius, protect connectors from contamination when not in use, and confirm compatibility with QSFP28 ports on your devices. For runs beyond typical rack-to-rack distances consider alternative multimode OM4/OM5 or single-mode solutions as appropriate.
