InfiniBand/fibre optic cable BlueOptics AT-QSFP-4SFP10G-5CU 5 m 4xSFP+ Black

The BlueOptics AT-QSFP-4SFP10G-5CU is a 5 m InfiniBand/fibre optic breakout cable with a QSFP connector on one end and four SFP+ connectors on the other. Designed for high-density networking and data centre applications, this cable supports aggregation of four 10 Gb/s links into a single QSFP port, enabling efficient connectivity between switches, servers and storage systems. The black jacket and compact construction suit rack-mounted environments where space and cable management are important.

Advantages

This cable enables consolidation of four separate 10 Gbit/s channels into a single QSFP port, reducing the number of individual connections and simplifying cabling runs. Its pre-terminated design removes the need for field termination and speeds up deployment. The male-to-male configuration ensures direct compatibility with standard QSFP and SFP+ ports, while the 5 metre length provides flexibility for typical rack-to-switch and switch-to-server connections.

Suitable for

• Aggregating multiple 10 GbE/SFP+ links into a QSFP port in data centres
• Direct connections between switches, servers and storage arrays
• High-density rack environments where cable bulk and management matter
• Short to medium reach interconnects inside server rooms or telecom cabinets

Key specifications

• Cable type: InfiniBand/fibre optic breakout cable
• Connectors: 1 × QSFP (male) to 4 × SFP+ (male)
• Length: 5 metres
• Aggregate bandwidth: supports four 10 Gbit/s channels
• Jacket colour: black
• Application: internal rack, data centre and equipment interconnects

How to use

Plug the QSFP connector into a QSFP port on a switch or aggregation device and insert the SFP+ connectors into the corresponding SFP+ ports on servers, storage or access switches. Ensure ports are powered down or follow hot-swap procedures recommended by your hardware vendor if changing live connections. Verify link status and speed on each endpoint after installation and check that transceiver port settings match the expected 10 Gbit/s operation.

Usage recommendations

For optimal performance, route the cable to minimise bends and avoid tight radius turns; maintain industry-standard bend radius for fibre optic assemblies. Use appropriate cable management to prevent strain on connectors and to keep airflow unobstructed in rack systems. Confirm device compatibility with QSFP-to-4×SFP+ breakouts in firmware or hardware documentation before deployment.
