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

The BlueOptics QSFP28-DAC-5M-SS InfiniBand fibre optic cable 5m Male/Male is a 5-metre high-speed interconnect designed for data centre and networking environments. It features QSFP28-compatible male connectors at both ends and supports high-bandwidth, low-latency links for server-to-switch and switch-to-switch connections. The cable is intended for short-reach, point-to-point links where reliable transmission and signal integrity are required.

Advantages

This QSFP28 InfiniBand cable delivers high data rates with reduced latency and consistent signal quality over a 5 m reach. The twin male QSFP28 connectors provide a compact and standardized interface that is commonly supported by modern networking and storage equipment. The cable construction focuses on durability and stable electrical/optical characteristics to ensure predictable performance in rack and cabinet installations.

Suitable for

• Server-to-switch high-speed connections in data centres
• Switch-to-switch interconnects within racks and across adjacent racks
• High-performance computing clusters using InfiniBand fabrics
• Storage arrays and SAN fabrics requiring low-latency links

Key specifications

• Cable length: 5 metres
• Connector type: QSFP28 male to QSFP28 male
• Interface standard: InfiniBand-compatible high-speed link
• Intended reach: short-reach/direct-attach applications
• Form factor: compact, quad-lane transceiver interface

How to use

Install the cable by aligning each QSFP28 male connector with the corresponding port on your networking or server equipment and insert until the connector latches. Ensure both ends are seated firmly and that the cable is routed to avoid sharp bends and excessive tensile stress. For optimal performance, keep the cable within its specified length and avoid routing near sources of strong electromagnetic interference. Verify link status through the host or switch management interface after installation.

Recommendations

Store and handle the cable according to standard fibre optic and high-speed interconnect practices: avoid tight bends, protect connector endfaces from dust, and use dust caps when ports are unused. When deploying in dense rack environments, plan cable routing to maintain airflow and minimise strain on connectors. Consult equipment documentation for compatibility and any required firmware or configuration adjustments to enable full bandwidth.
