InfiniBand/fibre optic cable Nvidia MFS1S00-H020V 20 m QSFP56 Blue

The Nvidia MFS1S00-H020V 20 m InfiniBand/fibre optic cable with QSFP56 connectors provides a single, long-reach connection for high-performance network links. Designed for data centers and HPC environments, this 20 metre blue cable supports QSFP56 interfaces on both ends to enable high-bandwidth, low-latency transmission over fibre. The cable is suitable for linking switches, adapters and storage systems where reliable optical connectivity and predictable signal integrity are required.

Advantages

This QSFP56 fibre optic cable offers high-speed data transfer and consistent signal performance across its full 20 m length. The optical construction reduces electromagnetic interference compared with copper alternatives and maintains low latency for demanding workloads. The pre-terminated QSFP56 connectors allow plug-and-play installation, and the durable jacket and connector strain relief are designed for repeated moves and rack deployments.

Suitable for

• Interconnects between InfiniBand or Ethernet QSFP56 ports in racks and across cabinets
• High-performance computing clusters and distributed storage systems
• Data center aggregation and spine-leaf topologies requiring 20 m reach
• Server-to-switch or switch-to-switch optical links

Key specifications

• Connector type: QSFP56 on both ends
• Cable type: fibre optic (single-mode/multimode not specified by vendor data)
• Length: 20 metres
• Color: blue
• Intended use: InfiniBand and high-speed optical networking
• Typical benefits: low latency, high bandwidth, EMI immunity

How to use

Install the cable by aligning and inserting each QSFP56 connector into the corresponding port until it clicks into place. Ensure both network devices are powered down or that hot-plugging is supported by the equipment before insertion to avoid connector or signal issues. Route the cable through rack channels or cable management accessories to prevent sharp bends and excessive strain; maintain the manufacturer-recommended minimum bend radius for fibre optic cables. Verify link status in the host or switch management interface and perform basic throughput or diagnostic checks to confirm proper operation.

Recommendations

Place and secure the cable away from high-traffic areas and sharp edges, and avoid tight bends to preserve optical performance. For critical links, verify compatibility of QSFP56 ports and transceiver settings in connected devices and test the link after installation. Replace the cable if connectors or the jacket show visible damage.
