BlueOptics Q28-AOC-15M-EE-BO InfiniBand optický kábel 15m QSFP28 konektor

The BlueOptics Q28-AOC-15M-EE-BO InfiniBand fibre optic cable is a 15-metre active optical cable with QSFP28 male connectors on both ends, designed for high-bandwidth, low-latency connections in data centre and high-performance computing environments. It supports the physical form factor and signal integrity requirements of QSFP28 interfaces to enable reliable 100Gb/s class links over a 15 m active optical link. The cable assembly is intended for use where electrical copper cabling reaches its practical limits and where optical transmission provides better signal quality and reduced interference.

Advantages

This 15m active optical cable offers long-reach connectivity compared with passive copper solutions, maintaining signal integrity across the full length while reducing weight and bending limitations associated with traditional copper cables. The QSFP28 male-to-male terminations provide a direct plug-and-play interface with compatible QSFP28 ports, supporting high data throughput and lower power consumption per bit compared to equivalent electrical interconnects. The optical construction reduces electromagnetic interference and is suitable for dense rack environments.

Suitable for

• High-performance computing clusters requiring low-latency 100Gb/s links
• Data centre top-of-rack and leaf-spine interconnects
• Server-to-switch or switch-to-switch connections with QSFP28 ports
• Environments where electromagnetic interference must be minimised

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male on both ends
• Length: 15 metres
• Supported interface class: InfiniBand / QSFP28 100Gb/s class link
• Transmission medium: Fibre optic (optical fibres)
• Typical use: Short- to medium-range high-bandwidth interconnects within racks and between adjacent network equipment

How to use

Insert each QSFP28 male connector into compatible QSFP28 ports on the devices to be connected, ensuring connectors are aligned and fully seated. Handle the cable by the connector housings and avoid sharp bends or kinks along the cable body; maintain the manufacturer-recommended minimum bend radius. Verify link status on connected devices and configure corresponding network or InfiniBand interfaces according to system requirements. If necessary, observe any host or switch firmware messages about supported AOC modules to confirm compatibility.

Recommendations

Use this cable in cooled equipment racks and protected cable runs to maximise reliability. Avoid routing near sources of mechanical stress or heat, and follow standard electrostatic discharge precautions when plugging or unplugging. For optimal performance, pair with devices that explicitly support QSFP28 AOC modules and check firmware release notes for interoperability notes.
