BlueOptics Q28-AOC-7M-SW-BO InfiniBand fibre optic cable 7m QSFP28 Aqua

The BlueOptics Q28-AOC-7M-SW-BO InfiniBand fibre optic cable is a 7 m QSFP28-to-QSFP28 active optical cable (AOC) designed for short-reach, high-speed connections in data centres and high-performance computing environments. It uses OM3 multimode fibre with a 50 µm core diameter and supports 100GBASE-SR4 Ethernet applications. The cable features LSZH (low smoke zero halogen) flame-resistant sheathing, a compact bend radius and QSFP28 transceiver-style connectors with integrated electrical-to-optical and optical-to-electrical conversion.

Advantages

This active optical cable provides high data-rate transmission with lower weight and greater flexibility compared with direct-attach twinax solutions. Built to industry SFF, IEEE and MSA specifications, the QSFP28 connectors include integrated I/O converters that simplify hot-pluggable installation. The OM3 multimode core and quality components contribute to stable signal integrity over the 7 m length, while LSZH sheathing reduces toxic emissions and smoke in the event of fire. Each cable is factory new and tested for compliance with common industry standards.

Suitable for

• Interconnects within rack equipment and between adjacent racks
• 100GBASE-SR4 Ethernet links in data centres
• High-performance computing clusters and InfiniBand networks
• Short-reach, high-density switching and server connections

Key specifications

• Length: 7 metres
• Connector type: QSFP28 to QSFP28 (active transceiver-style)
• Fibre type: OM3 multimode
• Core diameter: 50 µm
• Supported standard: 100GBASE-SR4 Ethernet
• Sheath: LSZH (low smoke, zero halogen), flame resistant
• Design: Active Optical Cable with integrated electrical/optical conversion

How to use

Connect each QSFP28 end to compatible QSFP28 ports on switches, network adapters or server interfaces. The cable is hot-pluggable; ensure devices are configured for 100G operation and that port firmware and drivers support AOC modules. Route the cable to respect the minimum bend radius and avoid sharp bends or mechanical strain. No external power or separate transceivers are required because conversion electronics are integrated into the QSFP28 ends.

Recommendations

For reliable performance, use this 7 m BlueOptics AOC for connections inside racks or between adjacent racks and maintain gentle routing with adequate cable management. Verify compatibility with QSFP28 ports and ensure devices support 100GBASE-SR4. Avoid exposing the LSZH sheathing to excessive heat sources and store the cable coiled without tight loops when not in use.
