BlueOptics AA1404035 InfiniBand/fibre optic cable 3 m QSFP 4xSFP+ Male/Male

The BlueOptics AA1404035 InfiniBand/fibre optic cable 3 m QSFP 4xSFP+ Male/Male is a 3-meter multimode fibre assembly designed to link QSFP ports to four SFP+ ports. It provides a single-cable solution for consolidating high-density connections in switches, servers and storage equipment, supporting high-speed serial links common in data centre and enterprise networking environments.

Advantages

This QSFP to 4×SFP+ fibre cable delivers a compact, low-latency connection that reduces the need for multiple separate patch leads. The integrated design simplifies rack cabling and improves airflow management compared with multiple individual fibres. Passive optical construction lowers power consumption by eliminating intermediate transceivers where supported, while the 3 m length offers flexibility for short to medium rack-to-rack or top-of-rack installations.

Suitable for

• Connecting QSFP-enabled switches to multiple SFP+ ports on servers or breakout panels
• Top-of-rack and middle-of-row data centre cabling where high port density is required
• InfiniBand fabrics and Ethernet networks operating at SFP+/QSFP speeds

Key specifications

• Cable type: multimode fibre breakout cable (QSFP to 4×SFP+)
• Length: 3 metres
• Connector configuration: QSFP male to four SFP+ male
• Typical use: short-reach high-density interconnects
• Latency: low-latency passive optical link when used without intermediate transceivers

How to use

Install the cable by aligning and gently inserting the QSFP connector into the QSFP port and each SFP+ connector into the corresponding SFP+ ports, ensuring the latch mechanisms engage. Route the cable to avoid sharp bends and maintain the minimum bend radius specified by the equipment vendor. Verify link status and port configuration on connected devices; if the system requires breakout mode or link aggregation settings, configure those in the switch or host firmware to recognise the 4×SFP+ breakout from the QSFP.

Recommendations

For reliable performance, keep connection points clean and use dust caps when ports are unused. Avoid bending the cable sharply and maintain appropriate cable management to reduce strain. Check device compatibility for passive breakout operation; where passive breakout is not supported, use active transceivers or appropriate adapters as specified by the hardware vendor.
