Nvidia MC2609130-001 InfiniBand/fibre optic cable 1 m QSFP 4x SFP+ Black

The Nvidia MC2609130-001 InfiniBand/fibre optic cable 1 m QSFP 4x SFP+ Black by MELLANOX is a short-reach interconnect cable engineered for high-density server and switch environments. This 1 meter cable terminates in a QSFP plug on one end and four SFP+ interfaces on the other, enabling direct attachment between QSFP ports and multiple SFP+ ports. It is intended for low-latency, high-bandwidth links commonly used in data centers, network racks, and compute clusters.

Advantages

This cable provides a compact, factory-terminated solution that reduces connector clutter and simplifies cabling in constrained spaces. It supports aggregated high-speed links while maintaining signal integrity over a 1 m distance. The QSFP to 4x SFP+ configuration enables flexible port conversion without requiring active electronics, offering predictable latency and power characteristics suitable for latency-sensitive workloads.

Suitable for

• Connecting QSFP ports to multiple SFP+ ports in rack servers and switches
• High-bandwidth links in data center top-of-rack and spine-leaf architectures
• Compute clusters and high-performance computing (HPC) environments
• Storage networks and SAN interconnects requiring short-reach fiber links

Key specifications

• Cable length: 1 m
• Connector type (one end): QSFP
• Connector type (other end): 4 × SFP+
• Function: InfiniBand / fibre optic high-speed interconnect
• Color: Black
• Intended use: Short-reach data center cabling

How to use

Install the cable by inserting the QSFP connector into the corresponding QSFP port and align the four SFP+ connectors with the target SFP+ ports. Ensure connectors are fully seated and retention latches (if present) engage to secure the connection. Verify link status on connected devices and confirm proper speed and lane mapping per the host and switch documentation. Route the cable to minimize sharp bends and avoid mechanical stress on connector ends.

Recommendations

Handle the cable by the connector bodies when plugging or unplugging to avoid stressing the fiber and contacts. Keep the 1 m cable run free of tight loops and maintain recommended bend radii. Use firmware and driver versions compatible with QSFP-to-SFP+ breakout configurations and reference vendor compatibility lists when integrating into production networks.
