BlueOptics Q28-AOC-3M-MV-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male

The BlueOptics Q28-AOC-3M-MV-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male is a 3-metre active optical cable engineered for high-speed interconnects in data centre and high-performance computing environments. It features QSFP28 connectors on both ends and supports the physical requirements of InfiniBand and similar 100 Gigabit-class interconnects, providing a low-latency, high-bandwidth link over a short reach. The cable is designed to deliver consistent signal integrity and to simplify connections between switches, servers and network adapters.

Advantages

This QSFP28 active optical cable offers electrical isolation and immunity to electromagnetic interference, reducing performance variability in dense rack deployments. Its fixed 3 m length provides predictable link characteristics and tidy cable routing in server racks. The male-to-male QSFP28 termination ensures compatibility with devices that accept QSFP28 ports for high-throughput interconnects, enabling reliable data transfer and reduced heat compared with equivalent copper solutions.

Suitable for

• Interconnects between switches and top-of-rack equipment in data centres
• Connections between servers and high-performance computing nodes
• Short-reach links for 100Gb/s InfiniBand or compatible QSFP28 interfaces
• Environments requiring electrical isolation and low latency

Key specifications

• Connector type: QSFP28 male on both ends
• Length: 3 metres
• Cable type: Active optical cable (AOC)
• Supported interface: InfiniBand and compatible 100 Gigabit-class QSFP28 ports
• Typical characteristics: low latency, high bandwidth, immunity to EMI

How to use

Insert each QSFP28 connector into the corresponding port on the devices until the connector latch engages. Ensure both ends are seated properly and that connected equipment is powered according to manufacturer instructions. The cable is designed for plug-and-play operation with devices that support QSFP28 AOC links; no additional transceivers or external power are required. Route the cable to avoid sharp bends, pressure points and sources of mechanical stress to preserve optical performance.

Recommendations

For optimal performance, use this 3 m QSFP28 AOC in short-reach links within racks or between adjacent racks. Maintain the minimum bend radius specified by the manufacturer, avoid kinks, and keep connectors dust-free by using protective caps when not connected. Verify compatibility with the host devices' QSFP28 and InfiniBand stack before deployment to ensure supported link rates and firmware compatibility.
