BlueOptics InfiniBand fibre optic cable 3 m QSFP28 Aqua

The BlueOptics InfiniBand fibre optic cable 3 m QSFP28 Aqua is a 3-metre active optical cable (AOC) with QSFP28 to QSFP28 male connectors designed for high-speed InfiniBand and 100GBASE-SR4 links. Constructed according to MSA QSFP28 AOC specifications, the cable integrates transmitters and receivers on each end to deliver multi-mode fibre optical transmission over short reach data center connections. The pre-assembled Aqua jacket and QSFP28 interfaces eliminate the need for field termination and reduce connector cleaning and attenuation concerns.

Advantages

This BlueOptics AOC offers certified MSA compatibility for direct QSFP28-to-QSFP28 interconnects and supports up to 100 Gbit/s aggregate data throughput on a 3 m link. Built with components from established communication suppliers, the cable includes integrated optical transceivers and supports Digital Diagnostics Monitoring (DDM/DOM) for real-time status of voltage, bias current, optical transmit and receive power, and temperature. Fibre optic transmission provides immunity to electromagnetic interference and low latency for high-performance computing and data centre environments.

Suitable for

• Interconnection of switches and routers in data centres
• High-performance computing clusters and InfiniBand fabrics
• Storage systems and server-to-server links requiring 100G links
• Short-reach multimode fibre links within racks or across adjacent racks

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active Optical Cable (AOC) with multimode fibre
• Length: 3 metres
• Maximum aggregate data rate: up to 100 Gbit/s (100GBASE-SR4 / InfiniBand)
• Form factor compatibility: QSFP28 MSA compliant
• Monitoring: Digital Diagnostics Monitoring (DDM/DOM) support
• Typical application: short-reach data centre and HPC interconnects

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 socket of the devices to be connected, ensuring the latch engages. Confirm that the host hardware supports QSFP28 AOC modules and DDM/DOM if monitoring is required. No field termination is needed; the pre-assembled cable is ready for plug-and-play operation. When removing the cable, press the QSFP28 latch and pull straight out to avoid damaging the connector.

Recommendations

Ensure both endpoints officially support QSFP28 AOCs and DDM/DOM to access diagnostic features. Route the 3 m cable to avoid sharp bends or tight bundles that exceed the minimum bend radius for multimode fibre. For reliable operation, maintain clean connector interfaces and verify firmware or hardware compatibility with the intended switch, router, or storage platform prior to deployment.
