BlueOptics Q28-AOC-1M-AT-BO InfiniBand fibre optic cable 1m QSFP28 Male

The BlueOptics Q28-AOC-1M-AT-BO InfiniBand fibre optic cable is a 1 metre active optical cable (AOC) with QSFP28 male connectors on both ends. Designed for high-speed links, it follows QSFP28 MSA form-factor conventions and supports 100GBASE-SR4 multi-mode optical transmission for short-reach, high-bandwidth interconnects in data centres and HPC environments. The cable integrates optical transceivers and electronics in a pre-assembled, factory-terminated assembly to provide a plug-and-play connection between compatible QSFP28 ports.

Advantages

The integrated AOC design eliminates the need for field-terminated fibres or patch cords and reduces insertion losses associated with manual splicing. Built to MSA-compatible QSFP28 mechanical and electrical specifications, the cable provides a compact, hot-pluggable solution for 100 Gbps links and simplifies rack-to-rack and device-to-device connections. Digital diagnostic monitoring (DDM/DOM) functionality is available to report parameters such as optical power and temperature when the host hardware supports it.

Suitable for

• Short-reach 100 Gbps interconnects in data centres and server rooms
• High-performance computing (HPC) clusters and switch-to-switch links
• Storage systems and high-density aggregation panels with QSFP28 ports

Key specifications

• Length: 1 metre
• Connector type: QSFP28 male to QSFP28 male
• Transmission standard: 100GBASE-SR4 (multi-mode optical)
• Cable type: Active Optical Cable (AOC) with integrated transceivers
• Supports digital diagnostic monitoring (DDM/DOM) when host hardware provides support

How to use

Install the BlueOptics Q28-AOC-1M-AT-BO by inserting each QSFP28 plug into the corresponding QSFP28 port on your devices while the equipment is powered and supports hot-pluggable modules. Verify physical seating by gently pressing until the connector latches. Ensure both ends are connected to compatible QSFP28 ports that support 100GBASE-SR4 or equivalent multi-mode QSFP28 interfaces. If DDM/DOM status is required, check that the host device exposes diagnostic data for the port.

Recommendations

Handle the cable by the connector housings and avoid tight bends near the connectors; maintain the minimum bend radius specified by the manufacturer. Use in environments and hardware certified for QSFP28 AOC operation and verify host compatibility before deployment. For troubleshooting, inspect DDM/DOM readings and confirm both link partners are configured for the same multi-mode 100G standard.
