InfiniBand/fibre optic cable BlueOptics 40G-DACP-QSFPZ5M-BL 0.5 m QSFP Male/Male

The BlueOptics 40G-DACP-QSFPZ5M-BL 0.5 m QSFP Male/Male is a short-length InfiniBand/fibre optic cable designed for high-throughput interconnects. This 0.5 metre cable uses QSFP form-factor connectors on both ends and is intended for use where low-latency, high-bandwidth links are required between switch ports, network interface cards or server uplinks in dense rack environments.

Advantages

This fibre optic assembly provides a compact connection with minimal signal loss and consistent 40 Gbit/s performance over a short distance. The QSFP male-to-male interfaces reduce adapter requirements and support easy hot-plugging in compatible equipment. Its short length helps with clean cable management in crowded racks and minimizes excess slack that can degrade airflow or complicate installation.

Suitable for

• High-performance computing clusters and InfiniBand fabrics
• Data centre top-of-rack and leaf-spine connections
• Server-to-switch and switch-to-switch links in dense layouts
• Environments requiring low-latency, high-bandwidth short links

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 0.5 m
• Rated data rate: 40 Gbit/s
• Cable type: fibre optic for InfiniBand/high-speed Ethernet interconnects
• Colour: blue

How to use

Connect each QSFP end to the matching QSFP port on network equipment, ensuring the connector keys align with device receptacles. Install the cable while equipment is powered according to your site procedures; QSFP interfaces typically support hot-plugging but follow vendor guidance for transceiver handling. Route the cable to avoid sharp bends and mechanical strain; maintain the minimum bend radius specified by your infrastructure standards to preserve optical performance.

Recommendations

For reliable operation, verify that connected devices support 40 Gbit/s QSFP links and appropriate link aggregation or protocol settings. Use this short 0.5 m cable for direct short-range interconnects inside racks or between adjacent units, and store spare cables in a manner that prevents kinks or tight coils.
