BlueOptics Q28-AOC-3M-GM-BO Cable de fibra óptica InfiniBand 3 m QSFP28 macho/macho

The BlueOptics Q28-AOC-3M-GM-BO InfiniBand fibre optic cable is a 3-metre active optical cable with QSFP28 male-to-male connectors, engineered for high-speed data transmission in data centres and enterprise networks. It supports InfiniBand connectivity and is suitable for short-reach links between switches, servers and storage arrays where reliable, low-latency signal transfer is required.

Advantages

This active optical cable provides the bandwidth and signal integrity necessary for 100Gbps-class InfiniBand connections while minimising electromagnetic interference and heat compared with copper alternatives. Its QSFP28 connector form factor enables compact port density in racks and chassis, and the pre-terminated, plug-and-play design reduces installation time. The 3-metre length balances reach and manageability in typical rack-to-rack or in-rack interconnect scenarios.

Suitable for

• High-speed links between switches and leaf/spine network fabrics
• Interconnects between servers and storage systems in data centres
• Short-reach connections inside racks or between adjacent racks
• Low-latency cluster and HPC (high-performance computing) environments

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active Optical Cable (AOC)
• Length: 3 metres
• Protocol compatibility: InfiniBand; suitable for 100Gbps-class links
• Signal characteristics: Low-latency optical transmission, immune to electromagnetic interference
• Operating environment: Designed for data centre and network rack installations

How to use

Power off devices if recommended by the equipment manufacturer, then insert each QSFP28 connector into the corresponding QSFP28 ports on the devices until the latch engages. Ensure ports are compatible with InfiniBand and rated for the intended link speed. Route the cable without sharp bends and avoid excessive tension or compression; maintain recommended bend radius for optical cables. After physical connection, verify link status through network management interfaces and perform any required configuration for InfiniBand fabrics or switch zoning.

Recommendations

For reliable operation, avoid kinking the cable and keep it clear of high-temperature sources and moving parts in racks. Use the 3m length for intra-rack or adjacent-rack connections to minimise excess slack. Validate compatibility with the specific switch and host adapters in your infrastructure prior to deployment.
