BlueOptics QSFP28-DAC-5M-LE-BL InfiniBand fibre optic cable 5m QSFP28 Female

The BlueOptics QSFP28-DAC-5M-LE-BL InfiniBand fibre optic cable 5m QSFP28 Female is a 5-metre direct attach cable designed for high-bandwidth links in data centers and enterprise networks. Equipped with QSFP28 connectors on both ends, this cable supports high-speed InfiniBand connections and is intended for short-range interconnects between switches, servers and storage systems where low latency and consistent throughput are required.

Advantages

This BlueOptics cable delivers low latency and reliable signal integrity for 100Gb/s class links in InfiniBand environments. Its 5 m length provides flexibility for cable management in racks and between adjacent equipment, while the QSFP28 form factor ensures compatibility with a wide range of QSFP28 ports. The cable is engineered to maintain stable performance under continuous operation and to simplify installation without additional transceivers.

Suitable for

• Short-reach connections between switches and leaf/spine architectures
• Direct links from servers to top-of-rack switches
• High-performance storage interconnects in clustered systems
• Low-latency computing environments and HPC clusters

Key specifications

• Connector type: QSFP28 female on both ends
• Cable type: Direct attach cable for InfiniBand
• Length: 5 metres
• Supported data rates: suitable for 100Gb/s-class links
• Use case: short-range, high-bandwidth interconnects

How to use

Connect the QSFP28 ends to the corresponding QSFP28 ports on network devices such as switches, servers or storage nodes. Ensure that ports support InfiniBand signaling and that cables are routed to avoid tight bends or mechanical strain. No additional modules are required; plug the cable directly into occupied QSFP28 sockets and verify link status through the device management interface.

Recommendations

For optimal performance, maintain proper bend radius, avoid sharp kinks, and secure the cable to prevent strain on connectors. Use in environments within the equipment manufacturer’s specified operating temperature range and verify compatibility with device firmware and port settings before deployment.
