BlueOptics QFX-QSFP-DAC-2M InfiniBand fibre optic cable 2m QSFP Male

The BlueOptics QFX-QSFP-DAC-2M InfiniBand fibre optic cable 2m QSFP Male is a 2-metre direct attach cable designed for high-speed connectivity in data centres and clustered networking environments. It provides a straightforward physical link between QSFP-enabled devices and supports reliable, low-latency data transmission required for InfiniBand networks and other high-throughput interconnects.

Advantages

This 2 m QSFP direct attach cable offers a compact, single-cable solution that reduces cabling complexity and helps maintain signal integrity over short distances. The cable is engineered for low latency and consistent performance in rack-to-rack and within-rack connections. Its QSFP male connectors are compatible with standard QSFP ports, allowing simple plug-and-play installation without additional transceivers.

Suitable for

• High-performance computing clusters and InfiniBand fabrics
• Data centre switch-to-switch and switch-to-server connections
• Storage systems and SAN interconnects requiring low-latency links
• Short-reach connections inside racks or between adjacent racks

Key specifications

• Cable length: 2 metres
• Connector type: QSFP male to QSFP male
• Interface: InfiniBand-compatible high-speed interconnect
• Design: Direct attach / fibre optic assembly for short-reach links
• Use case: Low-latency, high-bandwidth data transmission

How to use

Connect each QSFP male connector to the corresponding QSFP port on your devices, ensuring the connectors are aligned and fully seated. Route the cable to avoid sharp bends and excessive tension, keeping it clear of power cables and sources of electromagnetic interference. Verify link status on the connected devices and check firmware or driver compatibility for InfiniBand configurations if required by your environment.

Recommendations

For optimal performance, use this 2 m cable for short-reach connections such as within a rack or between adjacent racks. Avoid repeated unplugging and reinserting to reduce mechanical wear on QSFP connectors. Ensure environmental conditions in the rack meet manufacturer guidelines for temperature and airflow to maintain reliable operation.
