BlueOptics Q28-AOC-3M-NV-BO cable de fibra óptica InfiniBand 3 m QSFP28 conector macho

The BlueOptics Q28-AOC-3M-NV-BO InfiniBand fibre optic cable 3m QSFP28 Male is a 3-metre active optical cable engineered for high-speed, low-latency interconnects in data centre and high-performance computing environments. Featuring QSFP28 connectors on both ends, this cable supports reliable short-reach links between switches, servers and storage nodes while maintaining signal integrity and minimizing electromagnetic interference. Its compact design and 3 m length make it suitable for rack-to-rack or within-rack connections where consistent high bandwidth and stable performance are required.

Advantages

The cable provides high data throughput with reduced latency characteristic of InfiniBand QSFP28 interconnects, while the active optical design enables longer short-reach distances compared with equivalent copper assemblies. Its QSFP28-to-QSFP28 termination ensures direct compatibility with QSFP28 ports, simplifying installation and eliminating the need for separate transceivers. The fibre construction reduces susceptibility to electromagnetic interference and offers stable signal transmission in dense cabling environments.

Suitable for

• High-performance computing clusters and node interconnects
• Data centre switch-to-switch or switch-to-server links
• Latency-sensitive storage networking and backplane connections
• Short-reach fibre connections inside racks and between adjacent racks

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Physical medium: active optical cable (fibre optic)
• Target protocol: InfiniBand (QSFP28 form factor)
• Typical applications: short-reach high-bandwidth links in data centres

How to use

Insert each QSFP28 connector into compatible QSFP28 ports on your equipment, ensuring the latch engages and the connectors are fully seated. Route the cable to avoid tight bends and mechanical stress; maintain the manufacturer’s minimum bend radius to preserve optical performance. No separate transceivers or additional modules are required. After connection, verify link status through the host or switch management interface and confirm expected data rates and link health.

Recommendations

Store and install the cable in a clean environment, avoiding exposure to dust and contaminants on connector endfaces. Use dust caps when ports are not in use, handle connectors by the housing to prevent touching the optical surfaces, and avoid excessive pulling force. For optimal performance in dense deployments, plan cable routing to prevent sharp bends and to ensure adequate airflow within racks.
