BlueOptics Q28-AOC-7M-MR-BO InfiniBand-glasvezelkabel 7 m QSFP28 aqua

The BlueOptics Q28-AOC-7M-MR-BO InfiniBand fibre optic cable is a 7 m QSFP28 to QSFP28 Active Optical Cable (AOC) designed for short-reach, high-bandwidth interconnects. Constructed with OM3 multimode fibre (50 µm core) and LSZH flame-resistant sheathing, this cable supports 100GBASE-SR4 Ethernet and InfiniBand applications, converting electrical signals to optical and back via integrated transceiver modules in each connector. The AOC format combines the reach of optical links with the compact, hot-pluggable convenience of QSFP28 connectors for connections within or between adjacent racks in data centers and high-performance computing environments.

Advantages

The cable delivers high-speed 100 Gbps-capable performance over multimode OM3 fibre with a reduced bend radius and lighter weight compared with passive twinax Direct Attach Cable solutions. Built-in I/O and O/E converters in the QSFP28 heads ensure signal integrity across the 7 m length while maintaining compliance with SFF and IEEE specifications. LSZH outer sheathing provides low smoke and halogen-free characteristics for safer deployment in enclosed spaces. Each unit is factory-new and tested for quality and functionality prior to shipment.

Suitable for

• Rack-to-rack or within-rack connections in data centers
• 100GBASE-SR4 Ethernet links
• High-performance computing (HPC) clusters and InfiniBand fabrics
• Switch-to-switch or switch-to-server connections using QSFP28 ports

Key specifications

• Cable type: Active Optical Cable (AOC) with integrated transceivers
• Connector type: QSFP28 to QSFP28 (hot-pluggable)
• Length: 7 metres
• Fibre type: OM3 multimode fibre, 50 µm core diameter
• Supported standard: 100GBASE-SR4 / InfiniBand high-speed applications
• Sheathing: LSZH (Low Smoke Zero Halogen), flame resistant
• Bend radius: smaller bend radius than comparable passive twinax solutions
• Weight and flexibility: reduced weight and improved flexibility vs. DAC

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on your network equipment while the devices are powered according to the equipment manufacturer’s hot-plug guidance. Ensure connectors are aligned and fully seated until the retention latch engages. Verify link status using switch or host diagnostics and confirm that the port is configured for the intended 100G/InfiniBand link mode. When removing the cable, release the retention mechanism and pull straight to avoid stressing the transceiver module.

Recommendations

Use in controlled data center environments and avoid routing the cable through sharp edges or tight conduits; maintain appropriate bend radii and secure routing to minimize mechanical stress. Confirm compatibility with QSFP28 ports and switch firmware, and follow safety guidelines for LSZH cabling in confined spaces.
