InfiniBand/fibre optic cable BlueOptics 470-ABOB-BO QSFP28 AOC 10 m Aqua

The BlueOptics 470-ABOB-BO QSFP28 AOC is a 10 m Aqua-coloured active optical cable (AOC) designed for high-speed InfiniBand and fibre optic connections. Featuring QSFP28 connectors on both ends, this cable supports 100GBASE-SR4 compatible transmission and is intended for low-latency, high-bandwidth links in data centers and high-performance computing environments. Its active optical design transmits and receives optical signals via integrated transceivers, and the Aqua jacket provides easy identification in dense cabling environments.

Advantages

The AOC design delivers long-reach, high-bandwidth connectivity with low electromagnetic interference since optical transmission is immune to EMI. Built to MSA-compliant QSFP28 form factor specifications, the cable includes integrated optical and electronic components selected for stability and extended service life. The integrated digital diagnostics (DDM/DOM) capability provides real-time monitoring of parameters such as temperature, transmit/receive power and supply voltage when supported by the host hardware. The Aqua colour and 10 m length enable practical routing within and between server racks.

Suitable for

• High-performance computing clusters and GPU interconnects
• Data centre top-of-rack and end-of-row connections
• Switch-to-switch and switch-to-server 100 Gb/s links
• Storage arrays and SAN interconnects requiring low latency
• Environments requiring immunity to electromagnetic interference

Key specifications

• Cable length: 10 m
• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 to QSFP28
• Nominal data rate: 100 Gb/s (100GBASE-SR4 compatible)
• Colour: Aqua
• Supports digital diagnostics monitoring (DDM/DOM) when host supports the feature

How to use

Ensure both host ports support QSFP28 modules and the required 100GBASE-SR4 protocol. Align the QSFP28 connector latches with the port and insert until the latch engages; confirm a secure mechanical and optical connection. For DDM/DOM monitoring, enable diagnostic reporting in the host system management interface if supported. Route the cable to avoid sharp bends and mechanical strain; maintain the minimum bend radius specified by the rack or cable management system to preserve optical performance.

Recommendations

Handle the AOC by the connector housings and avoid pulling on the cable jacket. Install in clean environments and keep connector ends protected until final connection. Verify host compatibility and, where possible, test link status and DDM/DOM telemetry after installation to confirm expected transmit/receive power and temperature parameters.
