BlueOptics Q28-AOC-30M-CO-BO InfiniBand fibre optic cable 30m QSFP28

The BlueOptics Q28-AOC-30M-CO-BO InfiniBand fibre optic cable 30m QSFP28 is a 30-meter active optical cable designed for high-speed, low-latency interconnects in data centres and high-performance computing environments. Fitted with QSFP28 male connectors on both ends, this cable supports InfiniBand protocols and is intended for short- to mid-range link connections where copper cabling is impractical or where optical transmission is required to maintain signal integrity over longer distances.

Advantages

This active optical cable offers high bandwidth and stable throughput suitable for demanding applications. Its optical design reduces electromagnetic interference and supports longer reach compared with equivalent copper solutions at similar bit rates. The integrated QSFP28 interfaces provide a compact form factor compatible with standard InfiniBand ports, simplifying rack-to-rack or device-to-device connections while maintaining low power consumption and predictable latency characteristics.

Suitable for

• Rack-to-rack connections in data centres
• Interconnects between high-performance computing nodes
• Switch-to-switch or switch-to-server links requiring QSFP28 InfiniBand interfaces
• Environments where optical cabling is preferred to reduce EMI

Key specifications

• Length: 30 metres
• Connector type: QSFP28 male on both ends
• Cable type: Active Optical Cable (AOC)
• Protocol compatibility: InfiniBand (QSFP28 form factor)
• Use case: Short- to mid-range optical interconnects for high-speed data

How to use

Ensure both endpoints support QSFP28 InfiniBand interfaces and that equipment is powered down or supports hot-plugging per manufacturer guidance. Align each QSFP28 connector with the port and insert it until the latch engages; do not force the connector. Route the cable to avoid tight bends and maintain the manufacturer’s minimum bend radius. After connecting, verify link status on both devices and confirm expected data rates and lane configurations through system management or monitoring tools.

Recommendations

Store and handle the cable using gentle bends and avoid sharp kinks. Use appropriate cable management in racks to prevent strain on the QSFP28 connectors. For reliable performance, keep connectors clean and inspect them for damage before installation; follow host device guidelines for hot-plug operations and link diagnostics.
