BlueOptics QSFP28-100G-AOC-3M-BO InfiniBand fibre optic cable 3m Mint colour

The BlueOptics QSFP28-100G-AOC-3M-BO InfiniBand fibre optic cable is a 3-metre active optical cable engineered for 100G high-speed links. Equipped with QSFP28 connectors on both ends, this mint-coloured cable is intended for short-reach connections inside racks and between adjacent network equipment. It is suitable for data centre topologies and high-performance computing systems where a stable 100 Gigabit link and compact, low-latency interconnects are required.

Advantages

This fibre optic cable provides full 100G bandwidth over a 3 m active optical link while maintaining low power consumption and minimal signal degradation typical for active optical cabling. The QSFP28 connector format ensures compatibility with ports designed for 100 Gigabit InfiniBand or Ethernet QSFP28 interfaces. The mint colour makes cable identification and organised cabling runs easier in dense installations, reducing the risk of accidental disconnections during maintenance.

Suitable for

• High-performance computing clusters and node interconnects
• Data centre rack-to-rack and within-rack short-reach connections
• Switch-to-server connections requiring 100G InfiniBand or QSFP28 ports
• Network infrastructure installations where clear cable identification is beneficial

Key specifications

• Type: Active optical cable (AOC)
• Connector: QSFP28 on both ends
• Data rate: 100 Gbit/s
• Length: 3 metres
• Colour: Mint
• Typical use: Short-reach data centre and HPC interconnects

How to use

Ensure both devices have compatible QSFP28 ports and are powered off or prepared according to the equipment manufacturer's hot-plugging guidance. Insert each QSFP28 connector fully into the corresponding port until the latch engages. Verify link status through the host or switch management interface and confirm the established 100G link. For safe removal, follow the equipment's recommended procedure to disengage the latch and withdraw the connector while supporting the cable to avoid strain on the port.

Recommendations

Route the cable to minimise sharp bends and mechanical stress; maintain the manufacturer-recommended bend radius. Avoid exposure to liquids and extreme temperatures. Label both ends if used in large installations to simplify maintenance. If troubleshooting link issues, check port configuration, firmware compatibility, and replace the cable with a known-good unit to isolate the fault.
