BlueOptics QSFP28-DAC-5M InfiniBand fibre optic cable 5m Male/Male

The BlueOptics QSFP28-DAC-5M InfiniBand fibre optic cable 5m Male/Male is a direct-attach cable engineered for short-range, high-throughput interconnections. With QSFP28 connectors on both ends, this 5-metre cable supports data rates up to 100 Gbps and is intended for use in data centers, network racks and high-performance computing clusters where low latency and consistent link performance are required.

Advantages

This cable provides a compact and energy-efficient solution for 100 Gbps links, reducing the need for transceivers and additional modules. Its QSFP28-to-QSFP28 direct-attach design simplifies installation and helps maintain signal integrity over short distances. The cable is suitable for dense rack environments and supports the bandwidth demands of modern server-to-switch and switch-to-switch connections.

Suitable for

• Interconnects between servers and switches in data centers
• High-performance computing cluster links
• Top-of-rack and middle-of-row network cabling
• Environments requiring low-latency InfiniBand connectivity

Key specifications

• Cable type: Direct-attach copper/active copper (DAC) with QSFP28 connectors
• Length: 5 metres
• Connector type: QSFP28 Male to QSFP28 Male
• Maximum data rate: up to 100 Gbps
• Target application: InfiniBand and Ethernet high-speed links
• Design: Short-range, rack-optimized interconnect

How to use

Install the BlueOptics QSFP28-DAC-5M by inserting each QSFP28 connector into the corresponding QSFP28 port on the devices to be connected. Ensure ports are powered down or follow hot-plug guidelines from your hardware vendor if connecting live. Verify that the link is recognized by the host and that interface settings match the intended speed and protocol. Route the cable to avoid sharp bends and mechanical strain, and secure it within the rack to maintain airflow and accessibility.

Recommendations

Use this 5-metre QSFP28 direct-attach cable for short-range, high-bandwidth connections inside racks or between adjacent racks. Avoid exceeding the recommended bend radius and keep the cable away from sources of electromagnetic interference for optimal performance.
