## Summary description

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

## Long description

The BlueOptics Q28-AOC-7M-RW-BO InfiniBand fibre optic cable 7m OM3 is a factory-new active optical cable (AOC) with QSFP28 connectors at both ends. It is a 7-metre OM3 multimode solution with a 50 µm core diameter, designed for high-speed short-reach links in racks and between adjacent racks. The cable implements QSFP28-to-QSFP28 connectivity with integrated electrical-to-optical and optical-to-electrical conversion, supporting 100GBASE-SR4 Ethernet and InfiniBand transport while providing a lighter, more flexible alternative to direct-attach twinax assemblies.
Advantages
The cable’s active conversion electronics reduce signal loss over the 7 m length while maintaining compliance with SFF and IEEE MSA specifications. Its OM3 multimode fibre and QSFP28 interfaces deliver predictable performance for high-density environments. The low-smoke, zero-halogen (LSZH) jacket improves fire safety and reduces toxic emissions in enclosed spaces. Compared with direct attach copper twinax, the AOC offers lower weight, improved bend radius, and reduced cable diameter, simplifying cable management in data centres.
Suitable for
Short-reach 100G Ethernet connections within racks and between adjacent racks
InfiniBand high-performance computing links requiring QSFP28 interfaces
High-density switch-to-switch and server-to-switch connections
Environments where LSZH cabling is required for safety regulations
Key specifications
Connector type: QSFP28 to QSFP28 with integrated O/E and E/O conversion
Cable length: 7 metres
Fibre type: OM3 multimode fibre
Core diameter: 50 µm multimode
Supported standard: 100GBASE-SR4 Ethernet and InfiniBand links
Jacket: LSZH (low smoke zero halogen) flame-resistant sheath
Bend radius: improved (smaller) compared to twinax copper alternatives
How to use
Insert the QSFP28 connector plugs into the corresponding QSFP28 ports on your switches, servers, or adapters until the latch engages. Ensure both ends are securely seated and that connected equipment is powered according to manufacturer instructions. Because the cable contains active conversion modules, hot-plugging is supported on systems and ports that allow QSFP28 hot-insert; follow device documentation to avoid interrupting critical traffic. Inspect connector endfaces for dust or contamination before installation and use appropriate cleaning tools if necessary.
Usage recommendations
Route the cable to avoid sharp bends and tight tie points; maintain a relaxed bend radius to preserve optical performance. Use LSZH-compliant cable management in enclosed spaces and follow equipment vendor guidelines for QSFP28 transceiver compatibility. For reliable operation, verify firmware and port settings on connected devices to ensure support for 100GBASE-SR4 or InfiniBand link negotiation.
