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

The BlueOptics Q28-AOC-3M-QN-BO InfiniBand fibre optic cable is a 3-metre active optical cable with QSFP28 male connectors on both ends. Designed for short-reach, high-speed interconnects in data centres and high-performance computing racks, this cable delivers low-latency, high-bandwidth links between switches, servers and storage arrays. The single-cable assembly replaces copper direct-attach options where optical transmission is required for bandwidth, electromagnetic immunity and reduced weight.

Advantages

This 3m InfiniBand cable offers high data throughput suitable for 100Gbps-class links and minimizes signal loss through optical transmission. The QSFP28 male connectors provide a standardized interface for modern networking equipment, while the active optical design reduces power draw and heat compared with some copper alternatives. The cable’s flexible jacket and compact form factor simplify routing in dense rack environments and help maintain airflow.

Suitable for

• High-performance computing clusters and inter-node connections
• Data centre switch-to-switch and switch-to-server links
• Storage area network interconnects and backup systems
• Low-latency trading platforms and telemetry systems

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Intended use: Short-reach, high-bandwidth InfiniBand interconnects
• Transmission medium: Multimode optical link suitable for data centre environments
• Physical attributes: Flexible jacket, compact assembly for dense cabling

How to use

Verify that both network devices support QSFP28 ports and InfiniBand-compatible signalling before installation. With equipment powered down or ports disabled according to your site procedures, insert each QSFP28 male connector firmly into the corresponding port until the retention latch engages. Re-enable ports or power up devices and confirm link status through your switch or host interface. Monitor performance and error counters to ensure the link meets expected throughput and latency parameters.

Recommendations

Route the cable to avoid sharp bends and compressive loads; maintain the manufacturer’s minimum bend radius. Avoid running the optical cable alongside high-voltage power runs to reduce potential interference to adjacent systems. For critical links, test and record link performance after installation and keep spare cables on hand for rapid replacement in high-availability environments.
