InfiniBand/fibre optic cable BlueOptics Q28-AOC-7M-EE-BO 7m OM3 QSFP28

The BlueOptics Q28-AOC-7M-EE-BO is a 7-metre active optical cable (AOC) with QSFP28 connectors on both ends, designed for short-range, high-bandwidth connections in data centres and enterprise networks. It uses OM3 multimode fibre with a 50 µm core and supports 100GBASE-SR4 Ethernet applications. The cable includes integrated optic/electrical conversion in each QSFP28 module, providing a hot-pluggable link between compatible switches, servers and network appliances while offering reduced weight, improved flexibility and a smaller bend radius compared with direct-attach twinax solutions.

Advantages

The AOC construction delivers lower weight and greater flexibility than equivalent direct-attach copper assemblies, reducing mechanical strain in rack environments. QSFP28 transceiver-style connectors contain built-in I/O and O/E conversion, enabling plug-and-play operation for 100G links. LSZH flame-resistant sheathing minimises smoke and halogen release in case of fire, meeting common safety expectations for enclosed spaces. Factory testing and use of components from established manufacturers ensure consistent performance and interoperability with MSA-compliant QSFP28 ports.

Suitable for

• Short-reach 100G connections within racks
• Interconnects between adjacent racks in data centres
• High-performance computing and InfiniBand-capable network links
• Environments requiring LSZH cable sheathing for safety

Key specifications

• Cable type: Active Optical Cable (AOC), QSFP28 to QSFP28
• Length: 7 metres
• Fibre type: OM3 multimode, 50 µm core diameter
• Supported application: 100GBASE-SR4 Ethernet / high-speed data links
• Sheath: LSZH (low smoke, zero halogen), flame resistant
• Bend performance: smaller bend radius compared with twinax copper
• Connector: Hot-pluggable QSFP28 transceiver-style modules, MSA compliant

How to use

Ensure both network devices have compatible QSFP28 ports and support the intended 100G signalling standard. Handle the cable by its connector modules and avoid excessive bending near the module exit points. Insert the QSFP28 connector into the device port until the latch engages; the integrated modules perform electrical-to-optical conversion automatically. When removing, release the latch and pull the connector straight out to avoid damage. Keep fibre ends and connector housings clean and store the cable coiled loosely to preserve bend radius.

Recommendations

Use this 7 m BlueOptics AOC for intra-rack or adjacent-rack connections where 100G throughput and reduced weight are priorities. Maintain manufacturer-recommended bend radii, confirm device compatibility with QSFP28 AOC modules, and follow data centre safety policies for LSZH cabling.
