BlueOptics JNP-QSFP-DAC-1M InfiniBand fibre optic cable 1m QSFP Male/Male

The BlueOptics JNP-QSFP-DAC-1M InfiniBand fibre optic cable 1m QSFP Male/Male is a direct-attach cable designed for short-reach, high-bandwidth connections in data centers and high-performance computing racks. This 1-metre QSFP-to-QSFP assembly supports InfiniBand transport and is suitable for linking switches, adapters and storage systems where low latency and reliable data transfer are required.

Advantages

This 1m QSFP Male/Male cable offers a compact, low-power alternative to optical transceivers by eliminating additional transceiver modules and reducing component count. Its direct-attach form factor provides consistent signal integrity for high-speed InfiniBand links, simplified installation in dense rack environments, and a predictable physical profile for cable management. The cable is intended to deliver stable throughput and minimal insertion loss for short-distance interconnects.

Suitable for

• Short-reach server-to-switch or switch-to-switch connections in data centres
• High-performance computing clusters and InfiniBand fabrics
• Direct attachment of network adapters to top-of-rack switches
• Storage system interconnects where low latency is essential

Key specifications

• Connector type: QSFP Male to QSFP Male
• Length: 1 metre
• Protocol support: InfiniBand
• Form factor: Direct-attach copper/fibre assembly for short links
• Application: Short-distance, high-bandwidth interconnects

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP port on the devices to be connected, ensuring orientation and latch engagement. Verify that both endpoints are powered and that firmware or driver support for InfiniBand links is enabled on host adapters and switches. After connection, check link status indicators and use management tools to confirm negotiated speed and link health. For removal, depress the connector latch and withdraw the cable straight out to avoid stressing ports.

Recommendations

For reliable operation, route the cable with gentle bends and avoid sharp kinks; maintain a minimum bend radius recommended by the system vendor. Use in environments with appropriate ventilation to avoid overheating, and verify compatibility with switch and adapter models before deployment. Keep the connectors clean and capped when not in use to prevent contamination.
