Cabo de fibra ótica InfiniBand Nvidia MFS1S50-H020V 20 m QSFP56 2x QSFP56

The Nvidia MFS1S50-H020V InfiniBand fibre optic cable 20 m QSFP56 2x QSFP56 is a 20-metre multimode fibre link engineered for high-throughput, low-latency connections in data centre and high-performance computing environments. Designed to support QSFP56 interfaces, the cable provides a direct optical connection between QSFP56 ports, enabling reliable data transport for latency-sensitive applications and large-scale storage or compute clusters.

Advantages

This InfiniBand fibre optic cable delivers stable optical performance over a 20 m reach, with connectors and fibre transmission characteristics matched for QSFP56 ports. The design reduces electrical interference and offers consistent signal integrity, making it suitable for dense rack deployments and cross-rack links. The cable's construction focuses on durability and predictable insertion loss to support continuous operation in professional networking environments.

Suitable for

• Interconnects between QSFP56-enabled switches, NICs, and host adapters
• High-performance computing (HPC) clusters and cluster node connections
• Storage area network (SAN) links and large-scale data storage systems
• Data centre uplinks and cross-rack optical connections

Key specifications

• Length: 20 metres
• Connector type: QSFP56 to 2× QSFP56
• Cable type: InfiniBand fibre optic
• Transmission: Optical multimode designed for high-speed InfiniBand links
• Performance characteristics: Low latency, suitable for high-throughput data transfer

How to use

Inspect both QSFP56 ports and cable connectors for cleanliness before installation. Align the QSFP56 connector with the device port and insert until the latch engages; repeat for the dual QSFP56 ends as required by your topology. Ensure proper routing and strain relief within racks to avoid sharp bends in the fibre that could increase attenuation. Follow vendor guidance for link bring-up and verify link status using host or switch diagnostics to confirm stable operation.

Recommendations

Keep connectors capped when not in use and use appropriate fibre cleaning tools to maintain low insertion loss. Avoid tight bend radii and secure the cable to prevent movement that could stress connectors. For mixed vendor environments, verify compatibility of QSFP56 ports and firmware support for InfiniBand speeds before deployment.
