BlueOptics 100G-DACP-QSFP5M-BL InfiniBand fibre optic cable 5 m QSFP28 Black

The BlueOptics 100G-DACP-QSFP5M-BL InfiniBand fibre optic cable is a 5 m QSFP28 twin-ended assembly designed for high-bandwidth, low-latency interconnects in data centers and networking environments. The cable features QSFP28 male connectors on both ends, a robust black jacket, and is intended for short-reach high-speed links between switches, servers and storage arrays. The construction supports reliable signal integrity for 100 Gbit/s class connections while keeping insertion loss and crosstalk low.

Advantages

This 5 m BlueOptics cable provides a factory-tested channel for 100G InfiniBand links with QSFP28 connectors at each end. The cable’s compact design and durable jacket deliver predictable electrical and optical characteristics, helping to minimise latency and ensure stable throughput. Compatibility with common QSFP28 ports and attention to connector quality make it suitable for rack-to-rack and server-to-switch short-reach connections in dense installations.

Suitable for

• 100G InfiniBand connections between servers and switches
• Short-reach links in data centres and server rooms
• High-performance computing clusters and storage interconnects
• Replacing or installing QSFP28 direct attach copper/fibre assemblies for rack environments

Key specifications

• Cable length: 5 metres
• Connector type: QSFP28 male to QSFP28 male
• Rated data rate: 100 Gbit/s class
• Link type: InfiniBand-compatible high-speed interconnect
• Jacket colour: Black
• Application: Short-reach, high-throughput data centre links

How to use

Plug each QSFP28 connector securely into the corresponding QSFP28 port on network switches, servers or storage devices. Ensure devices are powered down or that ports support hot-plug operation according to the host hardware documentation. Route the 5 m cable through the rack or tray without sharp bends and avoid kinking to maintain performance. Verify link status in the host device’s management interface after connection and check for expected 100G link negotiation and signal levels.

Recommendations

For optimal performance, keep cable bend radius within manufacturer guidelines, avoid tight ties or compression, and use proper port retention mechanisms to prevent accidental disconnection. Confirm compatibility with your QSFP28 ports and firmware requirements before deployment, and label both ends for easy maintenance in dense cabling installations.
