InfiniBand/fibre optic cable Nvidia MC220731V-005 5 m QSFP

The MELLANOX InfiniBand/fibre optic cable Nvidia MC220731V-005 5 m QSFP is a 5-meter optical link with QSFP connectors on both ends, engineered for high-throughput, low-latency connections in data center and high-performance computing environments. The cable supports InfiniBand and optic network topologies, providing a reliable physical layer for switches, host adapters, and interconnect modules where consistent signal integrity and minimal latency are required.

Advantages

This 5 m QSFP fibre optic cable delivers stable, high-speed data transfer suitable for dense rack deployments and clustered compute nodes. The QSFP terminations ensure compatibility with standard QSFP ports and simplify installation in modern networking hardware. The optical construction reduces electromagnetic interference and maintains signal quality over the 5 m distance, supporting consistent throughput and low error rates under sustained loads.

Suitable for

• Interconnecting InfiniBand switches and host channel adapters in HPC clusters
• High-throughput links between servers and storage arrays in data centers
• Low-latency connections for database, virtualization, and AI workloads
• Replacing or extending existing QSFP optical links up to 5 meters

Key specifications

• Cable type: fibre optic for InfiniBand applications
• Connector type: QSFP on both ends
• Length: 5 meters
• Designed for high-speed, low-latency data transfer
• Physical form factor: QSFP-compatible optical assembly

How to use

Install the cable by aligning each QSFP connector with the corresponding QSFP port on your switch, host adapter, or network interface and insert until it engages securely. Ensure both ends are fully seated and that port LEDs or management software indicate an active link. Route the cable to avoid sharp bends and excessive tension; maintain manufacturer-recommended bend radius and secure the cable to reduce strain on connectors. Verify link speed and error counters through device management interfaces after installation.

Usage recommendations

Store and handle the fibre optic cable in a clean environment to prevent contamination of connectors. Inspect connector endfaces before mating and use appropriate dust caps when not in use. For optimal performance, avoid tight bends and maintain a gentle cable routing inside racks; consult network device documentation for compatibility and configuration settings specific to QSFP ports and InfiniBand fabrics.
