InfiniBand/fibre optic cable BlueOptics MC2609125-005 5 m QSFP 4xSFP+

The BlueOptics MC2609125-005 5 m InfiniBand/fibre optic cable with a QSFP connector and four SFP+ connectors provides a purpose-built link for high-speed server, switch and storage interconnects. This male-to-male direct cable supports consolidated connectivity between a QSFP port and multiple SFP+ ports over a 5 metre OM-rated fibre assembly, enabling reduced latency and stable data transmission in dense networking environments such as data centres and high-performance computing racks.

Advantages

This cable offers a compact, factory-terminated solution that eliminates the need for separate transceivers and patching for short-distance interconnects. The QSFP-to-4xSFP+ configuration simplifies port aggregation and migration tasks while maintaining signal integrity across the multimode fibre core. Its fixed length reduces signal loss variability and streamlines physical cable management inside racks and enclosures.

Suitable for

• Direct server-to-switch or switch-to-switch connections in data centres
• High-performance computing clusters and InfiniBand fabrics
• Port breakout or consolidation where a QSFP port splits to multiple SFP+ links
• Short-reach multimode fibre links within racks or between adjacent racks

Key specifications

• Connector types: QSFP on one end, four SFP+ on the other end
• Length: 5 metres
• Transmission medium: multimode fibre optics suitable for short-range data links
• Cable configuration: fixed QSFP-to-4xSFP+ breakout assembly
• Application: high-speed data centre interconnects, InfiniBand and Ethernet environments

How to use

Install the cable by inserting the QSFP connector into the QSFP port of the originating device and each SFP+ connector into the corresponding SFP+ ports of the target device(s). Ensure ports are powered off or that hot-plug procedures recommended by the device vendors are followed. Route the 5 m cable to avoid tight bends and mechanical strain; secure it with cable management accessories as required. Confirm link status and speed through the host devices once physical connections are complete.

Recommendations

Use this factory-terminated QSFP-to-4xSFP+ cable for short-reach multimode links inside racks or between adjacent racks. Avoid exceeding the recommended bend radius, keep connectors clean and protected when not in use, and verify compatibility with the QSFP and SFP+ ports and the supported protocols (InfiniBand or Ethernet) on your equipment before deployment.
